Abstract
Network restoration techniques will be vital to ensure B-ISDN service survivability in the event of high capacity link and node failures. Reliable ATM crossconnect networks can be implemented by the strategic pre-assignment of protection Virtual Path (VP) routes to permit recovery from a realistic subset of all possible failures, eg single span failures. The method of protection route assignment influences the quantity of redundant resources like spare capacity and Virtual Path Identifiers (VPIs), whilst nodal hardware costs are incurred due to the requirement of pre-stored alternate routing information. In addition to implementation costs, the impact that the choice of rerouting scheme has on other factors must be considered. For example, the degree of path elongation following restoration may adversely affect the delay performance of certain connections. Also, the amount of computation required to design the protection routes, and the effort needed to activate such routes have to be taken into account. This paper formulates metrics to facilitate a comparative evaluation of four distinct routing strategies for VP restoration, and in conjunction with a discussion of qualitative properties of each scheme, it concludes that failure independent rerouting is the preferred approach.
