Development and performance assessment of a distributed asynchronous protocol for real-time network restoration

The methodology used, and results obtained, in the development and verification of a protocol for real-time network restoration are described. This protocol, called selfhealing, relies on a combination of hardware and software features to achieve an advance in the speed of restoring network spans that have been cut. The hardware environment provides a paradigm for heavily parallel, asynchronous, distributed interaction. This environment is uniquely suited to interactions between digital cross-connect switches (DCS) embedded in a highly-capacity transport network. A speed determination based on an implementation of the protocol exactly as it would exist in the target DCS host machine is given.>
