Abstract
We address the problem of routing dynamic connections with differentiated reliability (DiR) requirements in wavelength-division multiplexing (WDM) mesh networks when spare capacity sharing is allowed. The problem is called routing with DiR (ROWD). In order to meet the reliability requirement of each connection request, not only an active path (AP) but also a backup path (BP) or a set of backup segments (BSs) should be derived. We propose two novel heuristics, single-protection-segment-based heuristic (SPBH) and auxiliary-graph-based heuristic (AGBH), for problem ROWD. While SPBH computes a single BS to protect the AP, AGBH computes as many BSs as necessary to protect the AP. Numerical results from extensive simulations demonstrate the good performance of the two algorithms.
