Robust DCN design for optical transport network resilience

Optical Transport Networks are continuously being upgraded to cope with the ever increasing capacity requirements. Optical Network resource planning aims at optimizing CAPEX and OPEX. However, resource planning can be carried out only for an ideal scenario. For a network to be resilient in case of failures, a robust DCN (Data Communication Network) plan is needed. In this paper, a robust DCN plan is designed to meet the OAMP (Operations, Administrations, Maintenance & Provisioning) requirements. Expected recovery time of OAMP for a segment over long haul DWDM network and actual recovery time measured are compared to validate the design.
