Point- To-Point Approach to enhance the performance for Survivable Fiber optic Networks

Abstract

In communication networks, survivability is an important aspect in newlineprotection and restoration. The main object of this thesis is to develop an newlineintegrated model, which describes the design of networks, with node and newlineswitch architectures. The proposed model gives a design tool to analyze newlineseveral partial mesh and hierarchical topologies, and demonstrates that newlinea hierarchical topology provides the most scalable solution for satisfying newlinethe design constraints. The design tool is to optimize the design based on newlinethe comparison of different network components. Protection and newlinerestoration strategies are proposed in order to achieve survivability in newlinemulti-layer networks such as physical layer and logical layer networks. A newlinemodel for multi-layer networks survivability which is based on a resource newlinesharing pool which avoids redundant protection in lower layer is newlinepresented. These are formulated by an algorithmic approach model newlineimplemented in C language and simulated by ns2 simulator. newline
