— As network utilization continues to grow in the coming years, there will be increased pressure on network operators to use traffic engineering to provision resources more efficiently. One way to do this is to allow backup paths associated with disjoint working paths to share bandwidth. Increasing the amount of sharing will naturally increase the risk that(More)
Developing optimized distributed protocols for large-scale networks is a challenging problem due to scalability and stability concerns. Scalability concerns can be naturally addressed by interpreting distributed protocols as a non-cooperative game of local protocol components attempting to maximize their individual utilities. One of the difficulties in(More)
A network operator who wants to provide recovery services to end-users has a range of options from which to choose. There is a fundamental trade off between recovery speed and robustness on one hand and the amount of resource overhead that is consumed by backup paths on the other hand. Several previous studies have examined this trade-off qualitatively and(More)
The amount of resource provisioning prior to failure events to support optical path recovery has a significant impact on network performance, and so designing recovery mechanisms for any large network necessitates balancing multiple (in some cases, competing) requirements. The Common Control and Measurement Plane (CCAMP) working group's Protection and(More)
