摘要：Optical fibre has been the main choice of communication medium for long-haul networks because of itslow transmission loss and high capacity of the data rate. A fibre cable can transmit many channels simultaneously usingwavelength Division multiplexing (WDM) technology. This makes possible to establish many different virtualtopologies on top of the physical topology. In this paper, dynamic programming model has been developed to producedifferent sets of traffic matrices for finding shortest path from each source to different destinations. On which existingHeuristic logical design Algorithm (HLDA) is implemented to find shortest path by varying number of opticaltransceivers. A study is made on stage wise 4-node, 7-node and 14-node NSFNET traffic matrices and comparativestudy has been done on utilisation of Average Weighted hops and Wavelength.
