Fast-Recovery and Optimization Multipath Circuit Networks Environments Using Routing Policies Different Administrative Distance and Internal BGP

Heterogeneity of Service Provider network connectivity on increasingly complex transmission networks and multilink transmission networks, so a link recovery system is needed that can minimize link and circuit link failures. Management of large distributed link connectivity and transmission line infrastructure with various business services that require link recovery systems when primary links fail or interrupt their paths. Increased internet and network coverage in terms of speed and cost efficiency of services to end-to-end latency, for customer service quality of service. The research objective was to implement and model Flexible Failover Using Routing Policies Different Levels of the BGP Hierarchy, for a Multipath environment for failure recovery processes with routing between BGP Autonomous System Internal and Policies Terms. Fast link failure and recovery mechanism in dealing with link failures and link congestion in service provider backhaul networks, at layer 3 and layer 2 by implementing BGP peering sessions with Routing Policies Different Levels of the BGP Hierarchy. The results obtained from the modeling that will be carried out in a multipath link environment, show and periodically generate the intervals obtained in the graph and test with the MRTG monitoring tool, have a direct average correlation with link failures. Failed link or node on primary link fails, secondary link is active and ready to perform recovery, then on tertiary link by selecting round-robin method to perform recovery. The process of removing the recovery link from the obtained results is 0-5.0-10 m/s.
