Implementation method of a core SONET/SDH switch with high capacity
JinQi Zhang · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2004
An implementation method of a core SONET/SDH switch with high capacity is introduced in the paper. High-speed serial I/O, switching architectures and design considerations for switching unit are involved. It supports strictly non-blocking for unicast traffic and re-arrangeably non-blocking for dual-cast. Dualcast traffic allows for efficient scheduling of working and protection paths in UPSR(Unidirectional Path Switched Ring)/BLSR (Bidirectional Line Switched Ring) applications.
