Abstract:
ABSTRACT This paper presents segmentation based heuristic approach as a solution to the design of a logical topology for a given physical topology. For a given physical topology in fiber optic network and Traffic pattern, the objective is to design a logical topology and routing algorithm so as to minimize both the average weighted number of hops and Congestion. Two constraints are considered namely, the number of wavelengths required to embed the resulting logical topology and the number of transceivers per node. Two new segmentation based heuristic approaches i) Segmentation Based Left Top to Right Bottom Diagonal Heuristic (SLTRBH), ii) Segmentation Based Left Bottom to Right Top Diagonal Heuristic (SLBRTH) are proposed to design logical topology for a given traffic matrix to a physical topology in fiber optical network. The experimental results on 14 node NSFNET model obtained for the HLDA and the proposed heuristics SLTRBH and SLBRTH and their performances are compared for two wavelengths and different transceivers. Keywords: - Physical Topology, Logical Topology, Traffic Matrix, Average Weighted number of Hops Count, Transceivers, Congestion, WDM Networks.
