Flexible network configuration in software-defined networks makes it possible to dynamically
restore flows. To this end, network devices carry out flow operations (ie, adding or removing …

Recently, traffic engineering mechanisms have been developed that guarantee that a
network (cloud provider WAN, or ISP) does not experience congestion under failures. In this …

Recently, researchers have started exploring the design of route protection schemes that
ensure networks can sustain traffic demand without congestion under failures. Existing …

We consider the problem of SDN flow optimization in the presence of a dynamic probabilistic
link failures model. We introduce a metric for path risk, which can change dynamically as …

Wide-area cloud provider networks must support the bandwidth requirements of network
traffic despite failures. Existing traffic engineering (TE) schemes perform no better than an …

The aim of this research is to enhance the performance of the Fast Re-Route (FRR)
mechanism by adopting a methodology similar in many aspects to that used in Software …

Link failures are a major threat that occurs within network topology. Probably link failures
occur due to low converging time, previously allocated delay and bandwidth, and iterative …

Software DefinedNetworking (SDN) is considered as a promising approach in networking
paradigm. It distinguishes the control plane of the network from the plane which is used for …

Software Defined Network (SDN) is an emerging network with clearer separation between
control and data planes. Like non-SDN, SDN undergoes a recovery process upon …

Software-defined networking (SDN) contains several sorts of network technology which is
used to design, build and manage networks. The abstraction of lower-level functionality in …
