Carrier and Metro Ethernet
Ethernet to the rescue
Exploding data traffic is forcing carriers to support multiple legacy and contemporary network technologies simultaneously over backhaul networks—leading to data throughput issues and operational inefficiencies. In the push to unify equipment across multiple network domains on a common backhaul technology platform, Ethernet has emerged as the technology of choice. Because of its assured scalability, simplicity in provisioning and management, and lower cost per bit of data transfer, Ethernet-based solutions are widely deployed by both wireless and wireline equipment manufacturers. It has evolved from being a pure LAN technology to a solution that can be deployed in high-performance Metro and Carrier telecommunication networks.
Carrier Ethernet is no longer seen as just a set of network technologies that provide value-added transport functions to the end-user—it’s now recognized as an opportunity to provide services to different customers. Carriers can connect customer sites on Layer 2 and become agnostic to IP or other Layer 3 protocol information about the customer network. The different service types cited in the Metro Ethernet Forum (MEF) specifications include E-Line, E-LAN and E-Tree, and these can be used for providing point-to-point, point-to-multipoint and multicast services.
