Enhanced Bit Repair IP Fast Reroute Mechanism for Rapid Network Recovery

The massive development of virtualized infrastructures, Internet Things (IoT), and Wireless Sensor Network (WSN) in recent years has led to an increase quality requirements for the management reliability underlay communication networks. Existing converged networks must therefore guarantee specific quantitative qualitative parameters different network services meet customer requirements. However, operated is very negatively affected by unpredictable failure a link or node. In such situations, typically interrupted period that difficult predict, which can lead significant financial losses other negative effects. Protocol Fast Reroute (IP FRR) technology was developed these reasons. paper presents proposal new Enhanced Bit Repair (EB-REP) IP FRR mechanism, offers improvements over its predecessor, B-REP mechanism. protection against single only selected critical flows. EB-REP provides advanced multiple failures protected domain be provided all calculates alternative paths advance based on metrics, but also allows construction independently them. uses standardized tunneling approach via unique field Bit-String. Thanks features, contribution solving FRR-related problems, enables use many deployments, especially solutions require reliable data transmission.
