Graph transformation approaches for diverse routing in shared risk resource group (SRRG) failures
2008
Computer Networks
Failure resilience is a desired feature of the Internet. Most traditional restoration architectures assume single-failure assumption, which is not adequate in present day WDM optical networks. Multiple link failure models, in the form of Shared-Risk Link Groups (SRLG's) and Shared Risk Node Groups (SRNG's) are becoming critical in survivable optical network design. We classify both of these form of failures under a common scenario of shared-risk resource groups (SRRG) failures. We develop graph
