PERFORMANCE IMPROVEMENT OF OPTICAL NETWORK USING DYNAMIC BANDWIDTH ALLOCATION

Abstract — Optical transport is evolving from traditional opaque networks that use all-electronic switching techniques toward all-optical transparent net-works. But there is a maximum transparent reach limit for signals in all-optical transparent networks that initiates the need for signal regeneration. An optical translucent network is a cost-effective, power-efficient solution, which 2R and/or 3R regenerators that bridge the gap between the opaque and transparent network architectures. Here contention resolution is achieved through the wavelength converter (WC). WCs is an expensive and power-consuming device that has to be shared in a network. WC sharing requires complex switching fabrics. In this project, we perform parameter analysis of different translucent networks based on asynchronous WC-sharing packet switches. To further improve the performance dynamic bandwidth allocation scheme is used.After modelling a set of translucent WC-sharing architectures their performance parameters are compared
