Abstract
SDN (Software-Defined Networking) provides a new approach to improve network security. In this paper, we design and implement a security service of transmission channels in SDN, which will efficiently lower the percentage of information leakage on the data plane of SDN networks. The core of the service is forwarding strategies based on multi-connection and time-slot scheduling, which functions on SDN controllers. According to the time-slot strategy, every data flow is transmitted on one path in a network at a certain moment, then in next time-slot it will be transmitted on another path, and so on. The multi-connection strategy allows to transmit data through multiple links at a same time. There is a client-side subsystem deployed in user terminals to process the data to send or receive. The processing of data including splitting and encrypting in application layer, coordinating with the forwarding strategies, reduces probability of the whole data flow being intercepted.
