IS-2003-22: Going the extra mile to bring carrier-class management to Ethernet in the first mile

The IEEE is finalizing a standard for applying Ethernet technology in the "first mile" (aka last mile, local loop, metro access and subscriber access network) outside buildings to link the building LAN to a WAN operated by common carrier. This paper argues that this Ethernet standard resolves "the mismatch" between customer needs and current solutions such as DSL, ISDN, cable TV, T1/E1 or T3/E3 lines with their shortcomings, ranging from performance bottlenecks, fixed bandwidth increments, limited scalability, lack of flexibility and provisioning complexity to quality of service issues and a high cost structure.
