FAILURE PROTECTION FOR SOFTWARE DEFINED NETWORKS USING MULTI-TOPOLOGY ROUTING BASED FAST REROUTE

Problem:

The data traffic being transmitted in the forwarding plane of software defined networks (SDN) may be disrupted due to the unexpected link/switch failures or planned maintenance tasks. The fast recovery from the network failures in the forwarding plane plays a crucial role in supporting the real-time services in SDN.

Technology:

Within the scope of invention, a software defined networking (SDN) controller and methods based on multi topology routing for protecting against failure of a network element in a forwarding plane are provided.

Advantages:

•Performance and efficiencies. •The recovery process from network failures in the forwarding plane can be controlled from a single point. This greatly simplifies the design and operation of the network. •The network failures in the forwarding plane can be automatically recovered without the manual intervention of a network operator. •Offering flexibility to perform failure recovery and traffic engineering tasks simultaneously.
