Abstract

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.

ONOS和Opendaylight SDN控制器对交换机和链路故障的弹性分析

视频会议应用从时延、抖动、带宽等方面要求高的QoS (quality service)。由于QoS参数严重受到即时拥塞和网络故障的影响，因此在网络层面采用的弹性机制直接影响到体验到的视频质量。除了传统组网下提供的解决方案外，软件定义网络(SDN)范式还提供了各种解决方案，即使在即时网络故障的情况下也能保持一定水平的体验质量(QoE)。不同类型的SDN控制器提供不同的弹性机制来从故障中恢复。恢复时间是保证视频会议体验满意的重要参数，较长的恢复时间会导致视频会议流冻结、流延迟甚至下降。本研究对比分析了ONOS和Opendaylight SDN控制器在链路和交换机故障情况下的恢复时间。
