Is 10 Gbps Internet the New Business Standard?

By: John Shepler

Internet bandwidths have been creeping up since the introduction of broadband more than two decades ago. Just when you think you have enough, you find that response from websites and cloud applications is too sluggish for you to maintain maximum productivity. It’s time for another upgrade, but that isn’t such a bad thing these days… if you do it right.

Why the Need for So Much Bandwidth?
What’s driving the need for ever increasing bandwidth is more data hungry applications. While the original Internet was most text-based, the next move was to images and then database operations. The introduction of video really started to suck up Mbps and Gbps as fast as they could be provided.

Now it is enormous file transfers, high definition video, including video conferencing, and the relocation of business critical applications from the server room to the cloud. Add e-commerce to that mix and you have a screaming demand for high speed low latency bandwidth.

The Changing Nature of WAN Bandwidth
The telecommunications world was founded on copper and wireless. Wireless persists in an evolved form, but copper is on the way out. Well, twisted pair copper telecom lines are disappearing fast. Coaxial cable copper has a new lease on life with DOCSIS 3.1 and 4.0 that are enabling it to compete with fiber. Wireless, too, can compete with fiber using 5G and, soon, 6G technology in the microwave range.

The big daddy of telecom is fiber. You can see fiber being trenched into nearly every right of way in cities and even smaller towns. Fiber goes under water to link continents. The Internet IS fiber, even if your access isn’t.

Fiber today isn’t the same fiber as yesterday. Oh, it’s still glass fibers fed by lasers. What’s different is the protocols. The telephone-centric SONET has given way to Ethernet over Fiber that is directly compatible with the Ethernet on your LAN. Packet switched networks have taken over from circuit switched networks.

The Good News About Bandwidth
The thought of ever accelerating bandwidth needs could give you pause except for one counter factor. The cost of that bandwidth is decreasing almost as fast as the speeds are increasing. You can get gigabit level fiber or cable broadband for what you used to pay for a T1 line. It is rapidly becoming possible for residential users to get gigabit level bandwidth over cable and PON (passive optical network) fiber. Wireless speeds in the hundreds of Mbps are also getting common. Any of these services may also serve smaller businesses well.

The next step up is in the multi-gig speed range, with 10 Gbps a new standard. It works well for businesses with many employees online, hospital and medical centers needing to transmit medical images, automated factories, video production and so on. If you already have Gigabit Internet or GigE service and are running into congestion, a 10 Gbps fiber line may be the perfect solution. For very high volume operations, even 100 Gbps isn’t unreasonable and is becoming more commonly available.

All Bandwidth Isn’t the Same
So far we’ve been talking about the Internet, the ultimate public commons. It’s a shared network by its very nature. Even so, most users with enough bandwidth find it works well for their purposes.

Internet access is also generally shared. Cable and cellular wireless are multi-user services without any priority or guarantee of latency. Because they are shared, these are the most affordable options.

The next step up is called Direct Internet Access or DIA. It’s a private line from your location to the Internet connection at your service provider. Being private means that you aren’t competing with dozens of other local companies or consumers for bandwidth, which can become scarce at times. The wireless equivalent of DIA is called 5G slicing.

Still need higher performance? Skip the Internet for a private lane all the way from your company to your cloud provider. Direct connection, another name for a private line, completely eliminates competition from other users to give you the best consistent performance. A 10 Gig Ethernet fiber private line is a premium service that may well fit your budget if you need to have the cloud behave like the servers down the hall.

Are you ready for 10 Gbps Internet or private line service? Don’t say no until you’ve checked prices for 10 GigE and higher business bandwidth. If 10 Gig is too much right now, you may opt for a fraction of that with the option to upgrade later. If 100 Gbps makes sense, large organizations may also find that within their means.

Is 5G Bandwidth Slicing The New Private Network?

The Internet is a wonderful way to connect… except when it isn’t. Oh, it works great for much of what we need: universal connectivity, rock bottom cost, and support for most applications. It’s when we need higher than usual performance or extreme reliability that our broadband connections can fall short. Latency, packet loss, and congestion can degrade interactive applications or make them impossible to implement. What to do? Switch to private networks.

What is a Private Network?
The Internet is what is known as a public network. It’s accessible by just about everyone, everywhere. All you need is an account at an ISP, cable company or cell phone provider and you’re connected with always-on broadband.

The beauty of this public network is that it has been built out over several decades so that it literally covers the world. Everyone has equal standing on the Internet. The average user’s traffic gets the same priority as a major corporation, research institute or any of the billions of “things” that are now connected online. This is what is known as network neutrality. The only preferences you can pay up for is a more direct connection to the backbone of the Internet and the amount of bandwidth you have access to.

All this equality sounds great, doesn’t it? Most of the time it serves everyone well. But, if you are trying to have a videoconference at the same time as everyone else is streaming a popular concert or engaged in an important phone call when the rest of the world is doing backups to the cloud, your connection may start to degrade. It’s much worse for high speed interactive gaming, remote surgery, high frequency stock and options trading, or control of an electric vehicle. These applications have a low tolerance for hiccups and delays.

The alternative to the public network is the private network. Your company LAN is a private network. It isn’t shared with every other company or consumers watching online TV. Chances are that it has all the low latency bandwidth you need all the time.

Now, extend that LAN across town or across the country. Can you do that? Yes, you can, but you won’t be building it yourself. Instead, you’ll contract with a network provider that offers private point to point connections. There will be other customers sharing their extensive facilities, but they won’t interfere with you. You will be guaranteed the bandwidth and other network characteristics, such as latency and packet loss, that you contract for.

Types of Private Networks
In the past, nailed-up twisted pair wires, T1 lines and SONET fiber were the way to go. Today, Ethernet over Fiber is the most popular along with MPLS networks.

Ethernet connections use the same protocol as your LAN, so they are easy to interface. You can also order direct point to point, point to multipoint, or mesh networks that connect multiple locations. Ethernet over Fiber offers bandwidths from 10 Mbps up to 10 Gbps, with 100 Gbps becoming more common.

Some popular uses for these Ethernet services include direct connections to cloud providers, interconnecting multiple business locations, and content delivery.

MPLS networks are a specialized technology that offers connectivity over wide areas, including the entire country or even Internationally. MPLS uses its own unique protocol, making it more secure than IP networks. These are multi-user networks, but are managed so that each customer has the bandwidth promised at all times. MPLS networks with Ethernet on-ramps can give you tremendous coverage at less cost than multiple private lines.

5G Slicing as the New Private Network
More and more applications are portable and mobile these days. That means a wired connection just won’t do. Instead, we settle for wireless Internet services, usually over the extensive cellular networks. This started becoming popular when 3G networks were implemented and really took off with 4G LTE. It’s only continued at a faster pace with 5G networks.

The limitation with even 5G is that you are still dealing with Internet broadband and its foibles. Bandwidth is more limited than with fiber and congestion can bring your applications to a crawl during busy times in crowded areas. A feature designed into 5G offers a way around this for an extra charge.

5G slicing technology allows carriers to partition or “slice” off a part of the available bandwidth for private use. Everybody is clogged up on the freeway, but you get to zip along on your own private road. Pretty nice, right?

5G slicing can give you a more direct connection to the Internet for better performance or can remain as a private network or connection to a private fiber network. It’s like your LAN, but with the freedom of being wireless over wide areas.

On their own campuses, some companies are implementing private 5G networks to gain the same advantages. 5G slicing takes this a step further to give you connectivity anywhere you go. That includes moving vehicles as well as smartphones, tablets and all those “things” the need connectivity but don’t perform well on the Internet.

Issues with 5G Slicing
The implementation of 5G slicing is just starting to roll out, so you may or may not be able to find this service yet. One concern is how much slicing can there be if everybody wants a private piece of the spectrum. While 5G bandwidth, especially on the new higher frequencies, is more plentiful, there are practical limits to how much traffic can be carried over the air. This is why there is still a mad scramble to make more frequencies available for 5G, including some spectrum currently assigned to the military.

Another potential bug-a-boo is the old network neutrality issue. How can a network be neutral when you can pay up for a private box seat? For now, regulators seem to be OK with 5G slicing as long as the main core of the network used for Internet is not prioritized, or that some services aren’t being throttled for competitive advantage. As more and more of the wireless spectrum goes private, it remains to be seen how much pushback there will be.
