SDN-enabled Framework for Resilient Traffic Routing in 5G Networks

In the 5G transport network, the router has some limitations in traffic engineering. In response to the diverse needs of the 5G mobile network, the SDN-enabled framework is introduced, which collects network topology information in a centralized way and analyzes network information for network path computation. In this paper, we proposed an SDN- enabled framework that is capable to provide resilient traffic routing for 5G application requirements. To verify the framework, we simulated a production scale network topology as input. Then, we leveraged K-Shortest Path Algorithm using different constraints to experiment the flexible traffic routing.
