Software-based fast failure recovery in load balanced SDN-based datacenter networks

Load balancing is currently considered as a candidate solution to tackle the emerging problem of increasing bandwidth demand in intra-datacenter networks. Furthermore, because a short disruption of data transfer would corrupt the result of a long procedure of computation, fast failure management mechanisms are considered as integral part of current datacenters. In this paper, we propose a method which uses active probing to detect and manage failures in an OpenFlow based datacenter network exploiting load balancing among equal cost multiple paths. The proposed method is scalable and effective based on the actions it takes without involving the controller in the fast failure recovery procedure

All-optical dynamic data center network (DCN) architectures are strong candidates to overcome those adversities, especially when they are combined with an intelligent software defined control plane. In this paper, we report the first harmonious integration of an optical flexible hardware framework operated by an agile software and virtualization platform. The LIGHTNESS deeply programmable all-optical circuit and packet switched data plane is able to perform unicast/multicast switch-over on-demand, while the powerful software defined networking (SDN) control plane enables the virtualization of computing and network resources creating a virtual data center and virtual network functions (VNF) on top of the data plane. We experimentally demonstrate realistic intra DCN with deterministic latencies for both unicast and multicast, showcasing monitoring, and database migration scenarios each of which is enabled by an associated network function virtualization element. Results demonstrate a fully functional complete unification of an advanced optical data plane with an SDN control plane, promising more efficient management of the next-generation data center compute and network resources.Peer ReviewedPostprint (author's final draft
