Provisioning of Data Service Traffic with Deployed Network Assets in Optical Networks

Abstract

Success of SONET/SDH standards over the last decade lead to wide deployment of SONET/SDH rings in incumbent carrier networks. Adoption of ring network architectures in metro and core networks is primarily due to their simplistic operation and fast protection times. In a typical incumbent SONET/SDH network, many of the rings are deployed in stacked configurations with some inter-connections. However, due to lack of time slot interchange (TSI) functionality, indefeasible right of use (IRU) use restrictions, inefficient design and provisioning of time slots, bandwidth is fragmented with very low utilizations of ring working capacity. High bandwidth data services cannot be provisioned on these rings as available capacity is stranded. Carriers constrained by CapEx budgets are looking for cost optimized solutions to harvest these existing network assets to improve operations, manage network growth with least CapEx and OpEx and migrating to converged networks.
