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.
