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 correct functioning of inter-domain routing is of vital importance to the ever expanding Internet. As a common threat to the Internet, prefix hijackings often hijack traffic destined to some Autonomous Systems(ASes), leading to routing black holes or traffic interception. In this paper, we study two typical categories of prefix hijackings, namely false origin hijacking and man-in-the-middle interception,...
Current intra-domain routing protocols computes only shortest paths for any pair of nodes which cannot provide good fast reroute when network failures occur. Multipath routing can be fundamentally more efficient than the currently used single path routing protocols. It can significantly reduce congestion in network by shifting traffic to unused network resources. This improves network utilization...
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...
High reliability is always pursued by network and protocol designers. Multipath routing can provide multiple paths for transmission and failover, and is considered to be effective in the improvement of network reliability. To compute multiple paths efficiently, we present MLSA, a tree based link-state multipath algorithm, to help a node to find multiple next hops for each destination. On each node,...
The decrease of AS-level route length, called Internet flattening, has a significance impact on the the design of next generation global routing system. However, there is little quantitative assessment of its factors. We report our findings through monitoring and analysis of inter-domain routing. Using BGP routing table and update messages from RouteViews and RIPE RIS, we explore Internet flattening...
