Ethernet Everywhere? We’re Almost There!
Written by John SchipperHe has been preparing for a long time. The hope is that all these networking standards will eventually be unified into a single standard. No more T1, DS3, OCx, whatever. Everything will be Ethernet one day. How close are we to that day? Well, we're almost done!
Network standards have already adopted EthernetCarriers do something I consider fashionable. They are abandoning their own standards in favor of Ethernet services.
Why? Because that's what the market wants. At one time there were all kinds of LAN standards. Remember when Token Ring was the next thing? What about AppleTalk?
Today, almost all network equipment has a connector and is designed for Ethernet. There are only two flavors: copper and fiber. Almost all office equipment has 10/100 or Gigabit Ethernet over twisted copper. Network equipment can have fiber connections for GigE, 10 GigE or 100 GigE.
This standardization made communication much easier. Standardizing the switch's local and Ethernet collision domains makes plug-and-play relatively easy.
The same thing happened with online software. The Internet standard, TCP/IP, has become the norm, making it easier to create and manage networks.
Make local networks talk to Telco
When you own a network, you decide how it works. When you design based on existing switches, routers, and cables, no one tells you otherwise. The big problem comes when trying to communicate with the outside world.
The Internet may be based on TCP/IP, but the WANs carrying it were not. Telephone company standards have evolved from a world of voice-only channels for making phone calls. The smallest channel T1, T3 (DS3) and OCx do are 64 kbps PCM encrypted phone calls.
Since it was digital, the solution was to do the conversion at both ends of the protocol so that it could be passed to an Ethernet LAN, say T1, to send over the distance and then switch to Ethernet at the other end. This process still works well and many T1 lines are still in use because sometimes they are all available in rural areas.
What do bees do?
Major telecommunications companies have been quietly migrating their networks to Ethernet for years. In many cases, this can be done over a basic Ethernet fiber protocol such as SONET. Competing service providers built their facilities with Ethernet in the middle of the network and never saw the evolution of TDM (time division multiplexing).
What's happening now is that service providers are asking the FCC for permission to shut down some of their older services, particularly those that run on copper and no longer have many customers. Standard POTS (Plain Old Telephone Service) is an endangered species. Fewer and fewer residential users own a conventional "landline". In addition to television and Internet, they have their own telephone service or simply use mobile voice communication.
Business continues on the road. Small businesses can get voice and data plans from existing cable companies or from carriers that operate in the same way as cable companies. Large enterprises are rapidly turning to VoIP and unified communications for business. They do not require traditional telephone wiring inside or outside the facility. Everything works online. External communication is carried out through a SIP line, dedicated private line, MPLS networks or a dedicated Internet access.
Is copper deadly?
Brass is always busy, but who knows how long. Growers want to get their plants out of those thick copper bundles, especially rows of individual pots.
T1 lines are still popular, but 1.5 Mbps throughput is increasingly the limit. The latest standard, Ethernet over copper, is very competitive and offers higher bandwidth or higher levels at a lower cost per megabit per second.
However, fiber optic connections are increasingly reaching commercial buildings in addition to cell towers. 4G and 5G wireless networks require more bandwidth than is practical with copper twisted pair. Most likely, all the duplicate copper will rust on the ground or be removed from the pipes and sold for scrap. Not so in most regions today, but not far off.
So where do I get Ethernet?
Currently, you can order Ethernet over copper or Ethernet over fiber in populated areas. In rural areas, Ethernet over DS1 uses a T1 line to connect Ethernet.
Remember it gives you wired broadband as well as an Ethernet connection and FTTP (Fiber to Building) is also 1 Gbps Ethernet.
Satellite and wireless Internet services are also offered over Ethernet. This includes 3rd and 4th generation mobile communications services for commercial use.
If you're living with an internet connection or an aging connection and wondering if there's anything better to choose from, you probably should. Get informed with a quick analysis of Ethernet services in your area and additional advice to help you choose the best solution for your business.
