Abstract

The SDH network self-healing mechanism is a very important content in research of SDH networks survivability and is also key to ensure network reliability. Based on the analyzing of traditional SDH self-healing ring, we proposed a new four fibers bi-directional intelligent path protection self-healing ring (BSHR/4IP) mechanism. By computer simulation, we estimate the performance of the proposed mechanism and prove that it has a high performance at restoration time, restoration ratio, utilization and complexity.
