Video conference applications require a high quality of service (QoS) from the point of latency, jitter, and bandwidth. As the QoS parameters seriously suffer from instant congestions and network failures, resiliency mechanisms utilized at network level have a direct impact on the experienced video quality. In addition to the solutions offered under traditional networking, software defined networking (SDN) paradigm also offers various solutions to keep quality of experience (QoE) at certain levels even in instant network failure situations. Different types of SDN controllers provide different resiliency mechanisms to recover from failures. Recovery time is an important parameter to keep video conference experience at satisfactory levels as longer recovery time causes frozen streams, streaming delays and even drops in video conferencing. This study gives a comparative analysis of the recovery time on ONOS and Opendaylight SDN controllers in case of the link and switch failures. |
