Executive Summary

The popularity of Ethernet is due to a number of reasons, not least the extreme cost-efficiency and the generally well accepted properties of Ethernet. The market potential for WAN services delivered with Ethernet interfaces is very substantial; Ethernet technology dominates the market for Local Area Networks (LAN), and Ethernet interfaces are ubiquitous, inexpensive and reliable. At the same time, the market for WAN services is growing. In the consumer market, DSL and cable services are gaining high momentum, and in business markets IT applications such as voice-over-IP and Storage Area Networks (SAN) are substantially increasing the requirements for WAN services.
