You can learn more about Carrier Ethernet essentials, services, and standards by downloading our eBook.īack in the early 2000s, when we started looking for a way to naturally extend the Ethernet protocol to provide Wide Area Network (WAN) connectivity, the industry introduced Carrier Ethernet (CE). The old party line concept may work with 20 close neighbors, but not with 20,000, and that’s where the evolution of Ethernet into Carrier Ethernet begins. The ubiquity and popularity of the technology has pushed it outside the LAN and across almost all aspects of network infrastructure.

Now, however, Ethernet is everyone’s favorite networking technology. If a collision was detected, the sender automatically waited a random time period (a millisecond or two), then checked again to see if the network was available to send data. It was expensive to run a separate phone line to each home, so the party line system was the logical, cost-effective solution to providing sparsely populated rural areas with telephone service.Įarly iterations of Ethernet worked similarly to the party line system: a network device first tried to transmit data and then listened for a collision with other activity on a commonly shared network segment. Okay, how many of us remember the party-line phone systems of the 1950s? Multiple houses shared a single telephone wire, which meant only one user could talk on the phone at a time. Take a look at the previous post, The History of Carrier Ethernet, to get a sense of where we are now. This is the second post in our Carrier Ethernet Essentials series.
