ABSTRACT
The article presents information on the performance of wide area Ethernet. Ethernet is making its move into the wide area market. Metro-area Ethernet services were pioneered by, startups like Yipes and Telseon during the late-1990s network boom and after a slow start, service revenues are now growing at double-digit rates. While startups introduced the concept, the incumbent local exchange carriers like SBC and Verizon are now in the best position to capitalize on the market. At a high level, the use of Ethernet as a wide area transmission technology has tremendous appeal both in terms of economics and simplicity. Ethernet switches are far cheaper than SONET transport and earlier-generation packet forwarding technologies. The Metro Ethernet Forum defines two different Ethernet services: E-LAN and E-Line. E-LAN is a switched service that uses carrier-based Ethernet switching equipment while on the other hand E-Line is essentially a high-capacity point-to-point private line connection between two LAN switches, supporting an Ethernet interface at each end.
