<title>Integrated traffic transport approach in optical networks</title>

Abstract

In this paper, we have proposed an integrated lightpath traffic transport approach to groom and transport the client traffic onto a dynamic logical topology established over the optical network. The integrated approach has been studied against the single hop and multi-hop approaches to demonstrate its benefit on improving the performance. We have implemented heuristics for the single hop, multi-hop approaches, and three variants of the integrated approach. Three traffic patterns and two types of bandwidth distributions, totaling six traffic scenarios, have been studied with regard to the blocking probability and throughput.
