PROJECT TITLE :
An Optimal Ring-Protection-Link Positioning Algorithm in Carrier Ethernet Ring Networks
Ethernet ring protection (ERP), outlined in ITU-T recommendation G.8032, could be a promising technology to realize the SONET/SDH-grade resilience in carrier Ethernet infrastructures. With its own loop prevention technique to block a link known as ring-protection-link (RPL) in an ERP ring, the ERP introduces a new optimization problem named RPL positioning whose objective is to seek out the optimal RPL location to attenuate the desired ring capacity for given traffic demands. During this paper, we tend to derive the optimal RPL positioning as an integer linear programming (ILP) downside and additionally propose an optimal RPL positioning algorithm for a lot of effective ring loading. By evaluations, we have a tendency to demonstrate that our proposed algorithm is indeed able to find the optimal RPL equal to the results by an exhaustive search emerged in previous works or the formulated ILP model. However, it is more efficient in computing time than the exhaustive search and also the ILP model.
