Compound OD Cycles for a Wide Variety of Survivability Policies in Transport Networks
Converged telecommunication networks, which simultaneously support a growing variety of services through a common network infrastructure, are aimed at significantly reducing network expenditures. This trend has encouraged the development of a unified network paradigm capable of supporting a wide variety of cost-effective recovery solutions, each of which may cope differently with fiber cuts and nodal equipment failures in order to satisfy service-dependent requirements. Expansion of the Origin-Destination (OD) Cycles approach is used to meet that challenge by offering ten different policies for survivability and their relative performance measures in terms of consumption of network resources and the resulting times of recovery. For practical purposes the scope of failure scenarios is limited to single and double-network failures only, even though the approach suggested is generic and can basically address even more complex events. Three test networks are extensively analyzed to demonstrate the paradigm developed and to present some useful observations about the relative positioning of the policies considered for survivability
