Simulation and performance analysis of routing in SONET/SDH Data Communications Network (DCN)

Abstract

This thesis analyzes the ITU-T G.7712 standard to evaluate the main features and specifications that are defined in the 11/2001 edition. The latest 03/2003 revision was also reviewed to determine what are the changes and latest update presented in that paper. In order to find out the compliance among telecommunication industry vendors, surveys were also conducted to determine which is the most widely supported standard. Finally, simulations were run using Opnet IT Guru software for the two routing protocols defined in the standard, ISIS and OSPF to examine of their characteristics and determine their usefulness. It was observed that OSPF achieves better performance and is the least obtrusive on network operations.
