Ethernet Comes of Age
Ethernet is here to stay, even if it isn’t the most efficient transport method for professional services. In that way, it’s sort of like the Borg; you will be assimilated, which even Ethernet inventor Bob Metcalfe acknowledged when he said, “When something rises up to defeat Ethernet, it’s very likely that they’re going to call it Ethernet.” Efforts such as the Metro Ethernet Forum’s drive to develop carrier Ethernet have gone a long way to solve the drawbacks the technology has for professional services, but there’s yet another variant that may be even better: connection-oriented Ethernet.
Author David Gutierrez, a product manager with Fujitsu Network Communications, discusses what this will mean for service providers. He writes: “Ethernet has a long history as a durable, flexible LAN technology. Its history doesn’t look to come to an end anytime soon with the advent of connection-oriented Ethernet (COE).
“Ethernet has been continuously reinvented through a series of improved standards. Today, it serves as a full transport solution that provides the benefits of both Ethernet’s inherent connection-less technology and of traditional circuit-based solutions such as SONET.
“Also known as IEEE 802.3, Ethernet owes its against-the-odds resilience to several attributes. It is an inexpensive, flexible and simple way to network latency-insensitive traffic within a single, well-bounded administrative domain. It’s also an open – as opposed to a proprietary – standard. These attributes have amounted to an open, collaborative and freely competitive soil in which the original Ethernet seed has flourished through a multi-stage evolution.” >>>>More
Yes, mobile companies are in desperate need of backhaul services, and, yes, providing backhaul is a great opportunity for service providers – but what comes next? Next-generation backhaul networks face a tough challenge: They must map out a clear path to 4G data technologies and still maintain current 2G and 3G traffic.
Fujitsu and CED hosted a presentation that covered the technologies necessary to equip backhaul networks to meet these challenges and to accelerate returns on investment. With Thomas Staniec, vice president of transport network engineering at Time Warner Cable; James Anthony, product planner for packet optical networking at Fujitsu; and Andy Fuertes, senior analyst and co-founder of Visant Strategies.
