Paper Abstract

In to day's access network, the challenges are current access technologies. We've built networks that are driven by bandwidth, both in the enterprise, on the campus, and in the carrier networks. On enterprises, we're delivering 100 megabits to the desktop. We're delivering gigabit uplinks, multi-gigabit switches at the core. On the other side, in the core carrier networks, the optical revolution of the past a few years has exploded the bandwidth capabilities almost at unimaginable rates. The challenge, though, is between that high bandwidth core network and our high bandwidth campus distributions, the wide area networks are still based on the technologies of the early '90s and even late '80s. We're bandwidth limited by El/Ti 5, by lowspeed ATM and frame relay networks, and they've driven us to a computing model that doesn't deliver the value the organizations need today. Here we propose the optical Ethernet to solve this problem. The fundamental definition of Optical Ethernet is based on taking the power of the Ethernet, that's evolved in the enterprise, and combining it with the power that we delivered in those core service provider optical networks, and putting them together to redefine the access network and the network end-to-end. The Optical Ethernet has the characteristics of the campus in terms of performance and speed and of service provider networks in terms or reliability and multi-site support. Enterprises can build private Optical Ethernets or use a service provider managed service, or a mixture of these two options. Optical Ethernet can be deployed on a MAN or WAN basis between major cities.
