The programmability of Software-Defined Networking (SDN) challenges the correctness and reliability of networks. There may be design flaws as well as implementation bugs in SDN applications. White-box testing methods with formal models rely on source codes, which limits the applicability of these methods. Black-box methods without behavior models cannot systematically cover an application's functions...
The Internet is playing an increasingly crucial role in both personal and business activities. Handling link failures is an important task in designing routing protocols. To enhance the network availability without incurring significant extra overhead, we propose a novel link protection algorithm, Hybrid Link Protection Scheme (HLP) to achieve failure resilient routing.
Traffic engineering under OSPF routes along the shortest paths, which may cause network congestion. Software Defined Networking (SDN) is an emerging network architecture which exerts a separation between the control plane and the data plane. The SDN controller can centrally control the network state through modifying the flow tables maintained by routers. Network operators can flexibly split arbitrary...
