Meshed MPLS Forms a Cloud of Clouds

MPLS networks have risen to prominence lately as replacements for old-school Frame Relay networks that link multiple business locations. MPLS networks are highly popular because of their ability to transport nearly any protocol with high quality and reliability. One remaining wish has been the ability to use a multitude of carriers at various locations and still have them interconnected by a managed MPLS network. That desire has now been realized.

AireSpring, one of the fastest growing and most innovative competitive carriers, is now offering what they call a Meshed MPLS Network. Just what does such a networking scheme do and how is it different from the meshed network connections inherent in any MPLS network?

MPLS networks can be thought of as classic clouds. You connect each of your locations to the cloud by means of a last-mile access network and then instruct the MPLS network operator how each location should connect to the others. These can be private point to point links, a star network with corporate headquarters at the center, or a meshed network arrangement. The meshed approach is highly popular because it allows any location to communicate with any other location at will. You don’t have to be actively managing or even monitoring the network, as the service provider takes care of that.

The one fly in the ointment is that you need to contract with one MPLS network provider for all your connections. That service provider will take care of getting the access connections, even if it means subleasing copper or fiber from another carrier. But what if you already have contracts with carriers to provide MPLS mesh networks for particular geographical territories?

This can happen easily if your company grew by mergers and acquisitions. It can also happen in decentralized organizations or conglomerates of businesses that haven’t traditionally had a need to connect with each other. Not all carriers have a nationwide footprint. It’s common for some carriers to be strong in parts of the country and not have a presence at all in others. All of this results in the head-scratching problem of how you tie together disparate WAN networks.

This is the problem that AireSpring’s Meshed MPLS Network solution addresses. Their MPLS Mesh (tm) creates a NNI (Network to Network Interface) that ties together multiple carrier solutions running at T-1 or higher speeds into one MPLS Virtual Private Network. You then have the choice of linking all of your sites into a single IP network or segmenting your data into multipole secure networks. Note that the segmenting can now be logical and not geographical.

Meshed MPLS technology gives companies a flexibility that they haven’t had before. You can now pick and choose which carrier you want to serve which locations to minimize your telecom costs. Quality of Service (QoS) mechanisms ensure that you can converge your entire network for voice, data and video. Your critical business applications will get the prioritization that they need for high quality performance.

Are you frustrated with your current hodge-podge of disparate telecom services that don’t quite perform the way you need and cost you a small fortune? It’s time to take a look a consolidating all that with a more advanced networking solution. Get MPLS network service pricing and features for all your business locations now. You’ll likely find you can have higher performance and lower cost at the same time.

Fixed Mobile Convergence Comes To the Cloud

Most business professionals today are toting smartphones as well as tablets and netbooks or laptop computers. At the office, there’s a large monitor desktop computer connected to the company LAN and a desk speakerphone. The challenge? How do you make these devices part of a unified whole?

This is the challenge corporate IT departments have been wrestling with as the variety of communications devices has multiplied faster than the means to interconnect them. Many times, the best option is to print new business cards with separate listings for office phone, mobile, FAX, toll free and email. Did you get an important call on your office phone while you were offsite making a presentation? Oops. You’ll get it when you get back to the desk tomorrow. Or you can call in and check your voice mails tonight, write down the number and then call back the client when business hours resume. Just hope your competition didn’t return the call sooner.

Modern solutions to this dilemma of integrating disparate tools into a common business system include enterprise VoIP, unified communications and fixed mobile convergence. Getting wireline or network voice telephony to mesh with cellular phones has been a particularly knotty problem. The one area of commonality has been the public switched telephone network. But the PSTN likes each device to have its own phone number. What if you want one number to be able to reach you no matter where you are or what phone is handy?

Smoothstone IP Communications specializes in converging voice and data networks.
They were first to introduce a converged voice and data service over an MPLS network. One of their specialties is hosted PBX or cloud based telephony. The beauty of hosted PBX is that you no longer need make a major capital investment every few years just to expand or improve your in-house telephone system. The expensive and complex switching system is provided as a service over a SIP trunk from Smoothstone to your company.

What’s new is that Smoothstone and Sprint are now partnering to include cell phones and smartphones within the cloud-based telephone system. Users get to have a single phone number, a single voice mail, abbreviated dialing plans and sophisticated group and personal call controls that would normally be available only within the office environment.

What’s tricky about this is to maintain full QoS or Quality of Service controls to ensure that voice services maintain enterprise levels of quality regardless of whether they are being handled wirelessly or through the company’s converged voice and data network. This is where the integration of Smoothstone’s cloud services and Sprint’s 3G, 4G and Global MPLS networks seamlessly manage voice and data communications.

From a user or IT management perspective, the complexity of FMC is moved to the cloud where it is fully managed by the service providers. At the same time, Smoothstone’s other cloud based communications services are available as needed by a single office or a geographically diverse workforce.

Has your company hit a frustration level caused by yesterday’s voice and data networking solutions trying to meet today’s needs? Don’t try to re-engineer and finance a complete overhaul until you look at the options available to you with converged cloud-based voice and data network services. Check pricing and availability with a quick inquiry right now.

Advantage of Colocation Services

Businesses are often faced with make or buy decisions. Do you create a product or service in-house or go outside to a vendor who specializes in that field? The same question arises related to telephone and computer services. So, what’s the right answer?

Like most everything, technical services decisions are very specific to your particular situation at any given time. That’s why you should revisit these issues on a regular basis - say yearly. You know what the advantages are to buying and managing your telephone and computer systems in-house. What are the advantages to going outside?

I’m going to focus on a very specific set of services you can buy, called colocation. Colocation is not quite the same as going to the “cloud,” but there are some similarities. What colocation really means is moving your telephone and/or computing resources into another facility called a colocation center or carrier hotel.

As you might suspect, there are various degrees of colocation involvement. The one that generally comes to mind is packing up your data center equipment and shipping it to a colocation facility. Within this facility, you or the facility staff re-install your equipment in a locked caged area that is not accessible to other customers of the colocation center.

What’s the point of that? It’s an economy of scale in several areas. You’ll only save on real estate if you are pressed for space now or are paying a premium per square foot in a high rent building. But it’s not just the physical footprint that’s important. The “colo” center provides equipment racks, electrical power, cooling air and physical security. They have all the power you can possibly use and the HVAC equipment to carry away the heat from high performance servers and switches. They also have backup systems in place so that you don’t need to worry about power outages. That can be important if you are located in an area subject to storm outages or questionable power lines.

Many companies move to colocation centers simply for access to unlimited amounts of cheap bandwidth. Cheap is relative, but bandwidth costs per Mbps at colocation centers are probably better than you can get at your facility. There are multiple carriers located in the same building who establish points of presence for their fiber optic networks. Construction costs are minimal, if anything, because it’s just a matter of getting a drop from a carrier’s cage to yours. If you are in a location where you are bandwidth limited, with no fiber options or sky-high construction costs, simply relocating to a colocation center can solve the problem. You still communicate with your remote facilities using T1 lines or other available bandwidth.

In addition to facilities, colocation centers are staffed around the clock. This is a real boon to smaller companies that can’t afford a 24/7 tech staff. Even larger companies may benefit from having server experts literally a few feet away from their equipment at all times. You can maintain your own equipment, of course, or hire the center personnel to perform upgrades and patches.

You also have the option to rent equipment rather than supply your own at many colocation centers. Why come up with the capital expense for new servers every few years (or few months) when you can rent fully managed servers dedicated for your use only? This approach can also make sense for telephone equipment. Why have an expensive PBX phone system on your premises and the staff to keep it running, when you can use a remote PBX that an expert provider buys and maintains?

These questions are the heart of make-buy decisions. More and more, companies are finding it makes more sense to rent from a large facilities provider than maintain equivalent systems in-house. How about your business? Could you do better at a colo center? Find out by getting colocation services prices and availability that you can compare with your own costs to make an informed decision.

Smoothstone’s Converged IP Cloud Expanding To Europe

Smoothstone IP Communications, an innovator in the new field of cloud-based unified communications, is expanding its service portfolio to include European locations. Could this be the start of a cloud that covers the Earth?

You bet it is. Thanks to international MPLS connectivity, it is now feasible to port any IP service to anywhere on Earth. That’s the beauty of MPLS networks. They take whatever you’ve got and transport it anywhere users can connect to the network.

Well, it’s not quite that simple. There’s a matter of scaling involved. Servers that easily handle the load for a limited universe of users in a regional area can become quickly overloaded when a tsunami of new users joins the network from a global footprint. Likewise, the core network has to have the bandwidth needed to handle the increased traffic without degrading latency, jitter and packet loss characteristics.

Smoothstone has addressed these issues, partially by expanding their cloud-based applications platform into several European data centers. That removes a potential bottleneck that could form if all packets needed to be processed through a single U.S. data center. It also makes call termination to off-net European phones easier and less costly.

One of the advantages that Smoothstone touts for moving enterprise voice services to their IP cloud is that internal phone calls stay on the network even when those calls are transatlantic to the UK, France, Germany or Switzerland. It’s only when calls need to be terminated to the PSTN (Public Switched Telephone Network) that connection costs are incurred. The more local the call termination, the cheaper it is. That argues for geographically diverse data centers and central office equipment to support telephony in the cloud.

What is also significant is that Smoothstone is not merely another VoIP service provider. The heart of their competitive portfolio is unified IP communications services. That means converged voice and data services to gain the cost advantages that come from deploying one network among business locations rather that separate telephone and data networks. Convergence can be a tricky proposition for time sensitive applications like network voice. If not done properly, VoIP calls can degrade into clipped and garbled conversations. Calls can even be dropped in extreme cases.

MPLS networking is especially suited to supporting converged voice and data. Not only are multiple protocols supported, but these privately owned and operated networks are carefully managed to ensure Quality of Service (QoS) at all times. For companies that want to unify their communications among multiple locations, it’s hard to argue against a solid MPLS core network. Now smoothstone is taking a leadership position to expand the very same converged services to include European cities. By the end of 2010, they expect to be providing applications and services across Europe.

Is your company still suffering from last century’s networking solutions? Have you been stymied by the process of creating unified communications that delivers the quality of service you require? What you need is the right provider with assets and resources to deliver the right solution for your size of operation and be able to seamlessly scale up as your business level increases. See how Smoothstone and other cloud networking services can provide the connectivity you need at a cost that makes sense.

Telephony In The Cloud

Thinking about cloud networking, what normally comes to mind is meshed data networks transferring packets from location to location. But some companies are also moving their telephone services to the cloud. What advantages and challenges does this present?

In a way, the original public switched telephone network is the oldest existing example of a cloud network. It is a managed system, carefully engineered to assure availability and quality of service, that serves a vast number of users simultaneously. Each customer connects to the cloud via a direct line to the nearest cloud port at the local central office. Users don’t really care to know what goes on in those vast switching offices. They just want to be able to make a call from one location to another at will.

Some companies engineer their own telephone cloud networks using ISDN PRI digital lines to connect PBX systems at multiple offices. The advantage of doing this compared to using the public network is that you don’t have to pay for each call. Only those calls to and from the outside world are subject to a fee.

The more modern approach is to set up converged voice and data networks between business locations so that only one network need be maintained. MPLS networks are often used to implement this cloud network, as they are capable of maintaining quality of service at reasonable cost. On a large scale, this is known as enterprise VoIP. There may be only one IP PBX system at headquarters that coordinates all calls, or each location may have a smaller system. ISDN PRI trunk lines connect to the public telephone network for off-net calls.

SIP Trunking offers an alternative to the ISDN PRI trunk lines for transporting voice traffic. A SIP trunk is part of the VoIP system and acts as the network connection to a remote service provider. That service provider handles termination of calls to the public phone system as needed. Since they terminate calls for many customers, per minute costs can be lower than ordering phone lines locally.

Some companies go even further and get all their telephone services from the cloud. All they have is individual SIP telephones or analog phones with adaptors connected to their company LAN. A private line connection or SIP trunk connects to what is called a virtual PBX system at the service provider. It handles all telephone switching, on-net and off. This system is ideally suited to “virtual” companies that don’t have a bricks and mortar presence. The employees are scattered over a wide geographical area. Thanks to the virtual PBX, they are interconnected just like they would be within a physical office building. Even the receptionist is virtual, routing incoming calls by voice or keypad requests.

Would a cloud networking approach help your company improve productivity while reducing costs? You can find out with a simple inquiry to an expert consultant regarding enterprise VoIP telephone services.

MPLS VPN Access Solutions

You’re convinced that an MPLS networking solution is the answer to connecting your geographically diverse business locations. But just how are you going to connect to the MPLS cloud from all those locations?

What you need is individual access networks for each location that will connect to the ingress tag router serving that geographical area. Right now the most popular connection technology is the venerable T1 line. Why? Because T1 lines are almost universally available, highly reliable, private, symmetrical, and relatively high bandwidth. Relatively means 1.5 Mbps in both the upload and download directions. For many businesses that exchange data files and even some voice traffic, this may be enough line speed. That’s especially true for branch offices and retail locations that simply need to connect to headquarters. But some applications may be limited by a 1.5 Mbps ceiling.

The next thing you can do is take advantage of T1 bonding to increase access line speed. T1 lines are readily combined, or bonded, to double, triple or otherwise expand bandwidth. There’s a practical limit of around 10 or 12 Mbps for this approach, but that can be more than adequate for many needs. Even video and medical image transmission can get by with this level of bandwidth as long as demands aren’t too high.

What if you need higher bandwidth levels to access your MPLS network? DS3 is still a good intermediate level solution at 45 Mbps. It’s a mature technology and available in many areas, no not nearly as prolific as T1 when you get beyond the metropolitan and suburban cores.

How about Ethernet as an access solution? Metro and Carrier Ethernet services are highly popular for a number of reasons. First, costs are often lower and sometimes much lower than traditional last mile connections for the amount of bandwidth you are ordering. For instance, it is not uncommon to get 3 Mbps Ethernet service for the same price as a 1.5 Mbps T1 line. 10 Mbps Ethernet is probably the most popular choice for new connections. It is priced attractively and available in most metro areas.

Another feature of Ethernet access services are that they are readily scalable up to the capability of the installed port. You may well start out at 3 Mbps but then find you need to double or triple that as business activity picks up at a particular location. No problem. A simple phone call to your service provider may be all you need to get that location upgraded. That can happen rapidly and independently of connection speeds at other locations.

If you are originating and terminating Ethernet packets, it only makes sense to use Ethernet connections to access the MPLS network. The network itself can easily transport Ethernet as well as other protocols. This gives you the option to keep everything in the Ethernet protocol and perhaps even create a multi-location LAN for ease of network management.

Higher bandwidth access connections, such as DS3 or Fast Ethernet, require fiber optic connections. With your building lit for fiber, you may be able to scale your bandwidth up to OC3, OC12, or OC48 SONET levels or GigE and 10 GigE Ethernet.

E-NNI Helps Ethernet Go Global

Metro Ethernet service has been growing by leaps and bounds. That’s not surprising, considering that Metro Ethernet services generally offer higher bandwidths at lower prices than traditional telecom services. They also offer features such as virtual private line and LAN service that weren’t previously available. As business appetite for Ethernet in the WAN grows, it’s only natural that businesses look to connect everywhere through their Metro Ethernet connections.

Metro Ethernet was intended to be just that. The "metro" in Metro Ethernet means metropolitan. It’s a service that is perfect for connecting two or more business locations within the same city or greater metropolitan area. The geographical range of coverage is set by the service footprint of the carrier providing the service.

Many competitive carriers now base their core networks on IP packet switching technology, not the traditional circuit switching architecture. They’ve embraced Carrier Ethernet to offer Ethernet services that span metropolitan areas so that companies can interconnect branches in cities across the country.

What’s been more difficult is getting the same type of universal access that companies have enjoyed with the Public Switched Telephone Network. After all, the days of monopoly in telecommunications are long gone. What’s needed is a standardized way for all those competing carriers to exchange traffic so that their customers can have a much wider geographical presence. Thats what E-NNI is all about.

The Ethernet External Network-to-Network Interface (E-NNI) is an industry standard ratified this year by the Metro Ethernet Forum. It provides a way for carriers to exchange traffic without having to worry about losing service features or having to create ad-hoc interfaces carrier by carrier. A separate UNI or User Network Interface connects each customer to its respective carrier.

The E-NNI specification makes it easy for carriers to exchange voice, data and video traffic at Ethernet layer-2. This make switched networks that span multiple carriers possible. To the user, the Ethernet WAN may look like one large cloud. To the service providers, it is a collection of clouds interconnected by peering through E-NNI connections.

The ratification of the E-NNI standard is giving rise to Ethernet Exchanges, such as Telx, that provide worldwide interconnection services for service providers at a carrier-neutral facility. Rather than having to build-out their service footprints to everywhere customers want connections or going through the laborious process of negotiating Private Ethernet NNI agreements, carriers can simply connect with each other through an Ethernet Exchange so that each participant has access to a much larger geographical footprint.

Can you company benefit from the growth of Carrier Ethernet and the many services it offers? The best way to find out is to get a competitive quote for your connection needs, be they across town or to the other side of the globe.

MPLS VPN Advantages

MPLS VPN networks are more and more in demand by companies needing to link multiple geographically diverse business locations. These may be across town, across the country or around the world... or any combination. Let’s take a look at why MPLS networks are becoming so popular.

Branch offices, retail franchise operations, warehouses, factories and medical centers are no longer isolated entities. Once, the public telephone system was enough to tie related locations together. That phone system was also pressed into service to transmit information rapidly using FAX and then dial-up Internet access. Broadband Internet using a dedicated high bandwidth wireline service followed for direct digital transmission. Other dedicated lines were used as secure point to point connections for sharing sensitive business documents.

Some companies desired more complex networking arrangements, linking every location to every other location in a fully meshed wide area network. One way to do that is to roll your own star network with point to point dedicated lines to the main office. Frame Relay networks came about as a way to outsource all that networking and the high cost of so many dedicated lines. But Frame Relay was never planned to run at the bandwidths we need today.

What MPLS VPN networks do is provide a private networking solution that outsources the problem of connecting many diverse locations. The cost of operating the network is shared among the user base, which makes it very cost effective for each user compared to running their own completely private network.

Unlike the Internet, a MPLS VPN has security built-in and performance characteristics of the network are carefully controlled. This is especially important for companies that want to converge their voice, data and video networks into a single network that can carry all traffic. There are big cost advantages in network convergence. But it’s all for naught unless you can guarantee quality of service for all your traffic. MPLS networks have Class of Service mechanisms to ensure that bandwidth, latency, jitter and packet loss are carefully controlled.

MPLS VPN security is based on using a proprietary tag or label switching protocol in place of standard IP routing. As soon as IP packets are received by the provider edge router, they are inspected and a MPLS label is attached. It’s that label that is used to route the packets while they are on the network. It’s removed as they exit the network. It’s like the MPLS network is speaking a foreign language within its service footprint.

MPLS networks are also easily scalable. If you build your own network from T1 lines or DS3 services, it can be a nightmare to upgrade bandwidth across the network. With an MPLS solution, you simply request additional resources from the service provider. You can also add or delete service locations much easier than you may be able to with long haul point to point line services. You only need an access connection to the MPLS “cloud” which is at the service provider’s nearest point of presence.

EVPL Ethernet Virtual Private Line Service

You are probably familiar with private line services for business. A private line is one where you have exclusive use. An analog telephone line is a private line. So is a T1 voice or data line. Now there is something new is the mix. It’s the VPL or Virtual Private Line.

Telephone lines weren’t always private. Remember the party line? Decades ago, several houses in a neighborhood would be connected to the same physical line. If you picked up your phone to make a call, you might hear one of your neighbors already engaged in conversation. In the pre-Twitter days, listening-in on other phone conversations was often a form of amusement.

That lack of privacy is long gone for telephones. But shared digital services exist today, especially with public access Internet. No, you can’t casually eavesdrop on your neighbors email or Web activities, but if some of the users start heavily downloading large files, your Internet service will slow down. There are also tools available that allow anyone to monitor everything going over a particular WiFi hotspot. The whole Internet is one big party line in the sense that you can’t be sure who’s monitoring the traffic and what they might be doing with information they skim.

It’s the security risk and the lack of consistent bandwidth that have driven businesses to private line service. T1 lines are private lines. They offer the advantages of rock solid 1.5 Mbps bandwidth and exclusive use of the line. The disadvantage is that you pay for that line even when traffic is light or non-existant.

Ethernet also offers a private line service called EPL. It works like T1 in that it is a physical line connection between you and your service provider. The difference is that the protocol is Ethernet and you can often get scalable bandwidth, typically 10 Mbps.

If you have a private line service, why would you want a virtual private line service? For one reason, you may want private lines running from your headquarters out to a number of branch offices. With dedicate private lines, you need separate physical circuits for each of these lines. You pay for the exclusive full time use of each circuit and there may or may not be enough pairs of wire into your headquarters office to give you the number of private lines you desire.

Ethernet Virtual Private Line service, EVPL, uses a single physical copper or fiber circuit to connect you to the service provider. Within that circuit are multiple EVCs or Ethernet Virtual Connection. This is not a party line arrangement. Each EVC carries its own traffic to and from another location without any cross-talk or interference from other EVCs.

The power of EVPL is not only that you only need one network interface at each of your facilities, including headquarters, but that those virtual connections can be extended to other cities or states over the provider’s MPLS core network. The MPLS is a cloud network that carries traffic for many users, but the integrity of each user’s virtual circuit is maintained from point to point regardless of distance.

EVPL is also a switched layer 2 service, which means that you can use it to extend your LAN network across town or across the country. It’s the simplest way to bridge multiple LANs when they are not located in the same facility.

Can EVPL service be of benefit for your organization? Find out with a quick inquiry about Ethernet Virtual Private Line service. Our expert Telarus consultants will be happy to get you price comparisons and service level agreements so you can make the best decision for your company.

Covad Offers A Nationwide MPLS VPN Network For Business

Businesses with many office locations nationwide are getting a new secure networking option. Covad has just completed its Intelligent Network Platform designed to expand WAN networking capabilities at lower costs than you may be used to paying.

Covad has designed its MPLS VPNs for the small to medium size businesses and larger distributed enterprises that need to solve the problem of how to interconnect multiple business locations. That may be franchises, field offices, warehouses, retail locations, factories, hotels and other buildings. There are two problems to be addressed with any multi-location networking scheme. First is how you reliably and securely link all of the sites together. Second is how you do that cost effectively.

MPLS is becoming the new standard in private line communications. Previous solutions have included Frame Relay networks and T1 point to point telecom lines. MPLS stands for Multi-Protocol Label Switching, which hints at its power. This is a system that will transport whatever protocol you require, be that switched circuit telephone calls, enormous data downloads, or broadcast video. It’s a network cloud in the sense that it has the capability to connect any location to any other location. You simply specify what that connectivity is going to be and the network operator takes care of enabling those connections.

Covad describes its MPLS network as a VPN or Virtual Private Network. Being a privately run network, it is inherently more secure than a public utility such as the Internet. You can’t get data on or off the network unless you are a Covad customer. MPLS is not the same technology as the Internet. Special label switching routers are needed at every ingress and egress point to attach and remove the labels that are used to get data packets where they are intended.

Another advantage of MPLS networks is that they offer a means to prioritize packets to establish CoS Class of Service and QoS Quality of Service for traffic management. You know that if you send voice or video down the Internet, you are taking your chances on the quality of the real time transmissions. That’s because every packet is treated like every other packet and it’s just your bad luck if some node become congested and disrupts your data flow. As a managed network, MPLS networks can ensure that each packet gets the bandwidth and minimized latency that ensures high quality voice and video transport.

Do you need to network multiple locations with ensured quality at reasonable costs? If so, you need to investigate your options with Covad and other MPLS VPN Networks for Business.
