Ring network protection schemes that are supported by devices

22

Common ring protection schemes include ODUk SNCP and ODUk SPRing protection. ODUk SNCP protects services on line boards and services carried over OCh fibers using the dual feeding and selective receiving function of electrical-layer cross-connections. ODUk SPRing protection mainly applies to a ring network carrying distributed services. This protection scheme uses two different ODUk channels to achieve the shared protection of multiple channels of services among all sites.
