Feature Issue on Availability

Ethernet provides a simple and low-cost solution at high bandwidth for metropolitan optical networks. However, native Ethernet still lacks carrier-grade resilience and management schemes. We propose and demonstrate a low-cost robust Ethernet-over-fiber network architecture that can recover from both node and link failures in less than 50 ms and, furthermore, ensure that packet loss is avoided during fault restoration. We implemented and tested the architecture in a prototype network. The proposed scalable architecture works with commodity off-the-shelf Ethernet switches and handles network failures in arbitrary Ethernet-level topologies by the edge nodes of the network. We present the experimental results of the protection protocol implementation, showing that the 50 ms carrier-grade recovery time is achieved.
