英文摘要 | Aiming at the problem that single controller in SDN is prone to overload and lead to long delay, this paper proposed an edge control model based on SDN, which integrated edge computing into SDN-based network by layered deployment. Each edge controller charged all of the sub-edge controllers and switches deployed and traffic from network devices within its cove-rage area. In order to manage the interaction between edge controllers conveniently, the proposed model introduced a controller agent module that forwarded device requests to the parent controller or sent routing information to the child to coordinate the work between the controllers. The experimental results show that compared with the traditional SDN-based network, the proposed method alleviates the load on the main SDN controller, minimizes the delay between the forwarding plane and the control plane and improves significantly total processing latency and bandwidth usage, which relies on the computing and storage ser-vices deployed on the edge of the network device. |
