IP3 2024 – Software Define Network Management (Lot 10434)
This lot is generally related to communication networks. Techniques are disclosed to protect a software defined network from failure which uses multi topology routing based fast reroute by discovering a physical topology of forwarding plane. The system determines a primary forwarding table for each network device and stores in multiple multi topology routing databases. Also disclosed are techniques to determine a primary path for relaying network traffic, associate virtual topology, protect the path and program each device along the switchable primary path. The technology may be implemented in network equipment such as switches, routers, modems, base stations, etc.
