摘要：

In this paper, a software platform with generalized multi-protocol label switching (GMPLS) -based Intelligence Optical Networks (ION) capacity has been developed as the control plane for the transport network. The survivability was the crucial character of network. This automatic switched transport network (ASTN) simulation platform with the signaling, routing and link management protocols can simulate many survivability mechanisms. Three survivability mechanisms have been simulated as the example. They are 1+1 protection, SPFP and WPB. The results are compared in terms of five performance metrics which are blocking probability (BP), route length (RL), setup time (ST), Control Overhead and control overhead (CO). We analyze all the parameters in the article.
