Abstract:
Software-Defined Networking (SDN) based
architectures, such as Open Flow, offer a chance to
design such a control plane. The SDN controller
performs all complex functions, including routing
and security checks. Segment Routing is a new
emerging technology that enables source routing.
Segment Routing (SR) technology can enable
networks to achieve scalable SDN and traffic
engineering solutions. The problem of computing
bandwidth guaranteed paths for given flow requests
is a challenge. This proposed system presents fast
rerouting algorithm exploiting the link or node
failure to compute the optimal backup path (active
backup path). In this system, failure in network link
or node is detected by using the Open Flow switches
and recomputed the new optimal path using fast
reroute with segment routing. The goal of this
algorithm is to reduce the failure recovery time with
low complexity and decreases the packet overhead in
case of failure.
