Abstract

A system and method of nxSTS-1 bandwidth sharing and ring protection. Ring protection is protected. The system and method of nxSTS-1 bandwidth sharing by every node (110) on a nxSTS-1 ring (100) includes placing nxSTS-1s in the nxSTS-1 ring (100), creating a nxVT point-to-point or point-to-mulipoint connection within a nxSTS-1 pipe, and globally managing VT resources in the ring via a ring manager. The system and method of protecting a nxSTS-1 ring (100) includes in a normal mode, only having one ring manager as an active manager and if the active ring manager fails, making another ring manager a new active ring manager according to an election protocol, where every node on the ring can be a candidate ring manager.
