Why Symmetric Bandwidth?

By: John Shepler

Bandwidth is bandwidth and the more the better, right? Well, not so fast. There is bandwidth and then there is bandwidth. All connectivity solutions are not the same. Let’s see why.

Sharing Isn’t Always Caring
Some connections are dedicated. Some are shared. You need to know which you are ordering.

A dedicated connection means a fixed amount of bandwidth that you are contracted for and are guaranteed to have all the time. The classic T1 line, SONET fiber optic, and many Ethernet over Fiber and private wireless solutions are dedicated. They may be set up as point to point private lines , cloud connections or last mile Internet access.

The advantage of dedicated lines is that your network capacity is always there even when you are not loading it up to the max. This improves latency and congestion compared to your other choice, shared bandwidth.

Shared bandwidth connections have other company’s traffic on the same line as yours. You have no idea how many there are or what they are doing. You may well feel their presence, however, as your WAN connection speeds up and slows down for unknown reasons.

So, why on Earth would you share bandwidth? Simply to save cost. Shared lines are dedicated lines that the carrier has sliced and diced to support many users instead of just one. If there is enough bandwidth and not so many users, you may not have a problem and can save considerably on monthly rates. Typical shared bandwidth services include cable broadband, wireless 4G LTE and 5G, and some passive optical fiber optic services that are available at bargain rates.

Symmetric vs Asymmetric Bandwidth
Symmetric bandwidth is when you upload and download speeds are the same. Asymmetric bandwidth means that one direction has much more capacity than the other. The high speed link is almost always the download path. Download speeds may be 10x faster than upload speeds.

Why? Asymmetric setups were designed to mimic the way people actually use the Internet. For the most part you download videos much more often than upload them. You enter short addresses in your browser and download web pages and content far more than you upload them. Or… Do you?

Business users may use their networks much more symmetrically than typical residential users. Business users likely transfer large files back and forth. Many of their applications reside in the cloud with data flowing up and down. VoIP phone and video conferencing are inherently symmetrical. Voice and images go both ways. Remote back-up is asymmetric for the most part… but the other way. Most data is being uploaded to the remote storage.

Traditional telecom networks are designed with symmetric bandwidth in mind. Consumer solutions, which are also typically shared bandwidth, are asymmetric in nature. For casual users and small businesses this may not be an issue. However if you are a heavy bandwidth user, depend on software as a service, do extensive video conferences or back-up your data to remote storage, you will likely be better served with symmetric and dedicated solutions.

Is your business running out of bandwidth or are you just frustrated with the solution you have now? Discuss your real needs with a technology expert and get quotes for multiple options that will work for you. There’s more available and at better prices than you think.

The Age Of Managed Networks Is Upon Us

It’s a sign of changing times. Competitive carrier AireSpring is now providing proactive networking monitoring free of charge to customers of its MPLS and Voice over MPLS solutions. That’s 24 hour continuous SNMP monitoring of the network that will generate alarms and reports if any deviation occurs. You can be sound asleep, but the NOC (Network Operations Center) will be keeping an eye on your MPLS network.

What heralds the future in this announcement is that service provider management of WAN services is on its way to become the default standard. That’s a far cry from the last half-century of bandwidth services. You ordered your dedicated lines, set up your networks and supplied your own staff to monitor operation. If something went haywire when the lights were off overnight, it got discovered and dealt with in the morning. A multi-national or otherwise 24/7 operation provided its own NOC to keep track of LANs and WANs worldwide.

Perhaps it has been the constant hammering on cost reductions caused by the deep recession that were are just now coming out of. Company budgets have been beaten down and beaten down to the point where business as usual a decade ago is just plain unaffordable anymore. Out of desperation, companies have sought out new methods of getting business done that don’t involve so many people and so much investment.

Into this opportunity gap have stepped the managed IT service offerings. That’s everything from outsourcing your entire IT department to partnering with suppliers to take over responsibility for maintaining the integrity of the line service you lease, to closing data centers and shipping the equipment to a colo center or selling it off in favor of doing everything in the cloud.

The common theme is lease versus ownership. Ownership certainly has its advantages. It also has its responsibilities. Medium and larger companies liked the idea of having everything under their tight control in-house. After all, who’s going to look after your interests like you do yourself? It’s easier to control security and network configurations when your people are running the show. If you have to go outside to get a connection, like you do with telecom services, you simply have the carrier nail up a line between point A and point B. If and when it fails, your terminal equipment will set off the alarms and you get on the phone to file a trouble report and then monitor the progress of the repairs.

What downsizing pressures and lack of available capital have done is slowly pry the tight grip of total control away from corporate staff in favor of letting outside suppliers provide some services and take responsibility for their performance. What many companies are discovering, to their surprise, is that providers can be trusted to deliver and maintain everything from networks to computing resources and business telephone switching.

Managed WAN services can be anything from a point to point T1 line to a complex international MPLS network with hundreds or thousands of connections. The demarcation point becomes the managed router rather than the smart jack. By installing Customer Premises Equipment (CPE), service providers have a view of everything on the WAN between your LAN edges. That includes all last mile connections as well as what’s going on with the core network.

That CPE is destined to move farther and farther into the local network as customers come to trust their IT service providers. Once they realize that the carrier or cloud provider is catching and fixing problems faster than they had been doing themselves, the reluctance to lease rather than own resources will fade away. The desire to return to an era of high capital investments, higher staffing levels and slow response to sudden demand changes will disappear. The flexibility of the company to adapt to change will correspondingly increase and older paradigms will seem as quaint as stacks of punched cards and racks of glowing vacuum tubes.

Are you being squeezed for investment capital and personnel, yet dependent on high performance information technology and telecommunications to be competitive? If so, perhaps now is the perfect time to consider managed IT and network services. Compare the costs and flexibility and see if managed solutions can be of service to your company.
