Aiming at the problem of failure recovery in current networks, a fast failure recovery method based on equivalent cooperative routing is proposed. Firstly, the transmission path between the source and destination nodes is divided into several non-overlapping path segments. Next, backup paths are deployed for each link in the path segment through segmented routing technology, which ensures fast routing...
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...
In this paper, we tackle the failure detection problem in OpenFlow networks. We have examined several commercial OpenFlow switches and found that the long failure detection time makes an OpenFlow network unable to realize fast failure recovery. To resolve this problem, we propose a software based failure detection and fault location identification scheme. Our design can be applied to both in-band...
In an OpenFlow network, the controller is responsible to control and manage the whole network. Although such central control paradigm is easier to achieve efficient network resources usage, the controller becomes the bottleneck when the network size is large. In this paper, we propose using pre-provisioned paths to mitigate the burden on a controller. The basic idea is to setup some background paths...
In this paper we introduce a new scheme to achieve fast failure recovery in IP multicast based content delivery, which is based on efficient extensions to the Not-via fast reroute (FRR) technique. The design of such an approach takes into account distinct characteristics of IP multicast routing, namely receiver-initiated and state-based, and it offers comprehensive protections against both simple...
In order to improve the survivability of IP networks, this paper presents a fast self-healing mechanism for distance vector routing protocol called FS-DVP.(Fast Self-healing distance vector protocol). The mechanism can dealing with network failures effectively through the precomputed multiple feasible next hops per destination. This local rerouting scheme guarantee the forwarding continuity in the...
In this paper, we investigate how to apply MIMO_NC in order to increase the efficiency of cooperative communications. MIMO_NC is a recent strategy to combine, in an integrated system, MIMO detection techniques and network coding. MIMO_NC is robust to channel errors, as it can exploit the spatial diversity provided by multiple transmissions of the same information, and throughput effective as it is...
