A New Planning Methodology for IP Networks with Dynamic Traffic Demand and Full Survivability Guarantee Against Link Failures

Recently the Generalized Survivable Network (GSN) was introduced to guarantee full survivability against link failures for dynamic demand networks. The GSN planning methodology is deterministic and easy to specify - requiring only the specification of input and output capacity of all the nodes. Here we demonstrate that the GSN planning framework can result in 2% - 19% cost saving when compared with the tree-based hose model planning methodology for planning a survivable IP network. The framework is applicable to the IP network carriers as well as the service providers who lease bandwidth from the network carriers.
