Managing Traffic Growth in Next-Generation Telecom Networks
This dissertation investigates how to optimally manage the traffic and its growth as well as the resources in a telecom network using optical Wavelength-Division Multiplexing (WDM) technology. A part of this dissertation addresses the Traffic Engineering (TE) problem, which determines how to set up explicit routes between source-destination pairs for various traffic demands so that the utilization of network resources is optimized. The authors' proposed algorithm also supports degraded-service, which is the amount of traffic that is guaranteed to be supported even in case of a failure. However, they need to not only employ efficient traffic engineering methods to utilize the existing network resources optimally, but also they need to periodically upgrade the network to meet the increasing traffic demands.
