Telecom leaders are finally realizing the benefits of carrier Ethernet globally, especially in many Asian economies, as network operators migrate to multiservice microwave systems to support backhaul and fiber extension services.

The dividends of implementing carrier-class Ethernet are clearEthernet is highly reliable, easy to implement and use, and highly interoperable. It is also easily configured and provisioned. Ethernet carries voice, data and multimedia traffic, which are now vital as applications converge in business, residential and mobile market sectors. For mobile operators, this results in reduced backhaul cost and the ability to serve higher-speed backhaul requirements, providing more bandwidth and higher throughput to serve multimedia applications.

Ethernet is far more scalable than SONET, ATM or frame relay technologies. Moreover, there are good reasons for moving to Ethernet. The technology is also attractive for providers moving toward IP- and packet-based networks. Many of these service providers are already deploying Ethernet in the access and aggregation parts of their network to serve IPTV, storage and similar applications as efficiently as possible.

Carrier Ethernet is now playing a significant new role in metro, edge and core networks as part of a mixed-technology solution, as Asia's mobile operators increase their focus on HSDPA technologies. Common hardware platforms are emergingthey use multiple access and trunking products to address standard plesiochronous digital hierarchy (PDH), Super PDH, SONET/synchronous digital hierarchy (SDH) and Ethernet.
