Abstract

Traditional methodologies for routing in media streaming is challenging because packets are not retransmitted when there is loss or corruption of packets. Thus throughput, packet loss rate or delay is not guaranteed. Providing multipath for every transmission helps in meeting efficient load balancing metrics. Software defined networking (SDN) approach is used to configure the network topology and increase the network performance and monitoring. Controller act as a centralized management device which monitors the overlay network. It reacts to network failures/changes by administering alternate routing instructions to the overlay nodes. The overlay network enhances different load balancing metrics. Dijkstra’s algorithm is used to solve the routing problem for find the shortest path. The proposed scheme is using an AOMDV multipath on-demand routing protocol which dynamically finds multipath. It experimentally evaluates performance metrics like end-to-end delay, throughput using AOMDV is compared with AODV.
