SYSTEM AND METHOD OF VIRTUALLY CONCATENATING VT1.5s ANS STS-1s OVER SONET AND SDH AND WDM

摘要

A system and method of virtually concatenating VT1.5s and STS-1s over SONET and SDH and WDM is provided. In an exemplary embodiment, the system and method includes (1) creating a nxSTS-1 virtually concatenated pipe out of STS-1s, (2) within the nxSTS-1 pipe, forming one or more nxVT pipes out of VTs, and (3) mapping an application to a nxVT pipe or a nxSTS-1 pipe based upon a service level agreement. In the system and method, the creating includes (a) terminating SONET framing, (b) processing pointers, and (c) compensating for delay, thereby aligning the STS-1s in the nxSTS-1 virtually concatenated pipe. In the system and method, the forming includes (a) processing VT overhead of the VTs and (b) mapping traffic to nxVT pipes or nxSTS-1 pipes according to a connection identification.
