A Novel Survivability Technique: DHMBC for WDM Optical Networks

摘要

Abstract Failures and malicious attacks in high-speed optical networks lead to huge data as well as revenue loss. In this paper, a survivability technique called Dynamic and Hybrid with Multiple Backup selection Criteria technique for high-speed networks has been proposed with the objective to minimize network resource utilization, blocking probability, End-to-End delay and maximize throughput. The proposed model decides the type of backup provisioning technique based on the location of failure in the network. Protection has been provisioned to selective links near to destination node and other links are restored. The simulation results indicate that proposed survivability technique is efficient as compared to conventional techniques in terms of various network performance measuring parameters. This technique inherits merits of protection as well as restoration. It can be practically implemented to provide resilience in future high-speed networks.
