Spare Capacity Utilization for Restoration of Mesh Based Networks

Free registration required

Executive Summary

WDM optical networks provide enormous speed & capacity. In case of any failure event due to any physical damage to the network or any other reason, the network should have restoration capability. Restoration requires planning and resources. There are several approaches available to ensure fiber network survivability. But efficiency and cost optimization becomes deciding factor. This study examines different approaches to survive link failures. The authors have used mathematical programming (using AMPL) for working capacity allocation model, spare capacity allocation model and joint capacity allocation model for mesh-based survivable networks.
