Today's fiber optic telecommunication networks are able to concentrate large volumes of traffic onto a relatively small number of nodes and links. As a result, the failure of a single network element can potentially interrupt a large amount of network traffic. Survivability is, therefore, an important issue in the design of fiber optic telecommunication networks.
Joining groups of nodes together in a "ring" configuration is a popular mechanism for protecting demand among nodes joined on a ring. To do this in the most cost-effective manner, the demands must be packed onto a ring with the smallest possible capacity. In my talk I'll discuss the resulting ring sizing problem and describe some simple heuristics for generating good feasible solutions.
