Abstract

In our paper, we present a heuristic method for maximizing the utilization of a survivable multi-ring DWDM network without wavelength conversion. We assume that the network is supporting packet and circuit based services simultaneously. The idea is that we can provide ample bandwidth or even dedicated channels to packet based services by sharing the resources in the protection ring under normal conditions. In case of a ring failure, the packet based channels can be compressed into fewer channels to yield protection bandwidth to circuit based services. Packet ring technologies such as Resilient Packet Ring (RPR) or IEEE 802.17 will ensure that all packet connections are still maintained in a fair manner under such condition. The main contribution in this work is to jointly consider the effect of packet and optical connection services on DWDM rings to enhance wavelength utilization.
