Detour planning for fast and reliable failure recovery in SDN with OpenState

Abstract

A reliable and scalable mechanism to provide pro- tection against a link or node failure has additional requirements in the context of SDN and OpenFlow. Not only it has to minimize the load on the controller, but it must be able to react even when the controller is unreachable. In this paper we present a protection scheme based on precomputed backup paths and inspired by MPLS “crankback” routing, that guarantees instantaneous recovery times and aims at zero packet-loss after failure detection, regardless of controller reachability, even when OpenFlow’s “fast-failover” feature cannot be used. The proposed mechanism is based on OpenState, an OpenFlow extension that allows a programmer to specify how forwarding rules should autonomously adapt in a stateful fashion, reducing the need to rely on remote controllers. We present the scheme as well as two different formulations for the computation of backup paths

Failure mitigation in software defined networking employing load type prediction

“…There has been much work on failure recovery [15], [2], [16]. The cited approaches introduce schemes based on failure detection and establishing preconfigured backup paths.…”

Technology-related disasters: A survey towards disaster-resilient Software Defined Networks

“…However, which actions to best take in which states is still a complex question and is not addressed in the paper. The authors refer to their prior work [32] to indicate that primary and backup paths could be computed. However, the technique used in [32] is that of mixed integer linear programming, which has an exponential running time and may be too costly to execute on large realistic networks.…”

Research on Data Security Mechanism among Cloud Services based on Software Define Network

“…Hartman and Wasserman M et al discusses the three kinds of authorization, authentication mechanism used in the possibility of SDN, especially in the case of cross-domain [22].first, through a proxy authentication; Second, direct distribution of cross-domain authentication credentials (such as symmetric key, private key certificate, etc. );Third, through joint certification (such as OAuth01 ABFAB1).One final way that united authentication, has the characteristics of flexible, easy to use in a variety of occasions [23]. But this does not give reference request, ABFAB in concrete application way of SDN.…”
