Abstract— As WDM technology matures and multicast applications become increasingly popular, supporting multicast at the WDM layer becomes an important and yet challenging topic. ...
— As an optical signal propagates along a lightpath to its destination in wavelength-routed optical networks (WRONs), the quality of transmission (QoT) is degraded by transmissio...
In this paper, we address the issue of traffic grooming in arbitrary WDM mesh networks. We present a novel groomer architecture wherein a combination of grooming at two different ...
— After identifying that current GMPLS specifications only allow for the implementation of a call blocking mode of operation that handles immediate-request calls (not book-ahead...
— We present a review of the various integer linear programming (ILP) formulations that have been proposed for the routing and wavelength assignment problem in WDM optical networ...
