Data Loss Prevention due to Link-flapping using Software Defined Networking

Data loss in high speed, high importance and critical data carrying networks like Defence Networks due to Link failures may lead to disastrous consequences. Link-flapping, a major contributor to Link failure is a very prominent occurrence in Traditional/Legacy networks which use routing protocols like OSPF and results in loss of data. Link-flapping occurring in critical networks where every bit of data is of extreme value and importance, affects communication reliability and can result in catastrophic failure of services. Even though mechanisms are present for preventing Link-flapping in traditional network devices like routers, still the data loss is prevalent. This paper proposes a method using SDN (Software Defined Networking) capabilities by which the effect of link-flapping occurrence in the network can be nullified while ensuring the uninterrupted flow of traffic and also providing a window for troubleshooting of the affected link simultaneously.
