This paper addresses the issue of reliable transport of emerging data services in Ethernet over SONET (EoS) networks that require protection guarantees beyond standard best effort delivery. We argue that the current consensus of using Ethernet spanning tree and a SONET 1+1 protection, while providing reliability, is an inefficient use of resources. Instead, we claim that EoS opens novel opportunities for protection heretofore unavailable in other environments. In particular, the deployment of… CONTINUE READING
