Abstract

We develop design theory and related operating concepts to support multiple differentiated levels of survivability assurances for individual demands in a transport network that uses p-cycles as the basic protection method. Notably this includes an ultra-high availability (dual span failure protected) service class that is based on principles that are unique to p-cycles for dual failure protection without dynamic reconfiguration of p-cycles. Results show that p-cycle based networks operating this way could offer dual failure protection to as much as 30% of all demands in the test cases with essentially the same redundancy as the single-failure protected design. These ideas and methods can enhance the cost-competitiveness of transport network operators and enable a range of service offerings to best suit actual customer requirements on transport survivability.
