Whitepaper: Revenue Recovery for Operational SONET/SDH Networks

by Optical Society of AmericaJan 01, 2008

SONET (Synchronous Optical Network) and SDH (Synchronous Digital Hierarchy) networks are widely deployed in enterprise and telecom networks as access and backbone networks. But the inventory systems for SONET/SDH networks are typically only 60-80% accurate. This paper published by Optical Society of America describes the large Synchronous Optical Network (SONET)/ Synchronous Digital Hierarchy (SDH) networks typically have 20-30% ""Stranded"" resources, both in wasted bandwidth and in untracked hardware. Author presents a novel approach that uses localized heuristics to uncover stranded resources and configuration errors based on field data alone.
