“…QoS refers to the service capability that a network can provide for network communication tasks. For different communication tasks, QoS needs to achieve different indicators, including packet loss tolerance, delay tolerance, link capacity and other metrics 32 . In the traditional single-path transmission mode, all QoS-related network parameters can be used for link weight calculation and the optimal path can be selected.…”

According to the research status of SDN(Software Defined Network) control layer traffic scheduling, we find the current common problems, including single path, easy congestion, QoS(Quality of Service) requirements and high delay. To solve these four problems, we design and implement a QoS-oriented global multi-path traffic scheduling algorithm for SDN, referred to as QOGMP. First, we propose a link weight calculation algorithm based on the idea of traction links and deep reinforcement learning, and conduct experimental verifications related to traction links. The algorithm considers QoS requirements and alleviates the problems of easy congestion and high delay. Then, we propose a traffic scheduling algorithm based on link weight and multi-path scheme, which also considers QoS requirements and solves the problem of single path. Finally, we combined the link weight calculation algorithm and the traffic scheduling algorithm to implement QOGMP, and carried out comparative experiments in the built simulation environment. The experimental results show that QOGMP is better than the two comparison algorithms in terms of delay and rescheduling rate.
