Time-Differentiated Resilience in Telecom Mesh Networks

Free registration required

Executive Summary

Many telecom, customers have applications with time varying reliability requirements. However, current frameworks for a Service-Level Agreement (SLA) provide the same reliability during the entire holding time, rather than providing high reliability only when required. Recent papers establish an SLA framework to support time-differentiated resilience using Critical Windows (CWs). CWs are scheduled, regularly repeating time periods where additional resilience is required. CW-oriented provisioning has been studied for specific end-to-end cases. The authors expand the previous work by investigating the structural properties of CWs in various dynamic settings, and propose a CW-aware provisioning scheme applicable for practical mesh networks.
