Do you know OTN ODUk Shared Protection Ring

Network survivability reflects the network in case of failure, Able to maintain the service capability, the survival mechanisms of the network, topology, available resources, coordination mechanisms for survivability has a significant impact. In terms of the transport network, SDH  survivability as one of the most distinctive part, to lay the basis of SDH transmission technology… Read More »
