Migration to a converged network has caused service providers to deploy real time applications such as voice over an IP (VoIP) network. From the provider's perspective, the s...
Abstract—We tackle the problem of providing minimum datarate guarantees for different classes-of-service in an OFDMAbased network, while obtaining a high system throughput. Our a...
The placement of regenerators in optical networks has become an active area of research during the last years. Given a set of lightpaths in a network G and a positive integer d, re...
