Link Failure Recovery Using Shortest Path Fast Rerouting Technique in SDN

摘要

Fast recovery from link failures plays a major role in networking due to loss of packets and transmission delay. Link failures must be addressed immediately as it may lead to congestion in the entire network and reduce the efficiency of the network. This paper mainly focuses on finding an alternate path to handle high priority packets with minimal delay when a link failure occurs in the network. The proposed work also focuses on distributing the traffic evenly through all the paths thereby finding a set of shortest paths to reach the destination. The experimental results show that the proposed system takes minimum time to recover from failures.
