Optimization of distributed tunnel rerouting in a computer network with intermediate node feedback

Optimization of distributed tunnel rerouting in a computer network with intermediate node feedback

In one embodiment, a head-end node determines a path for un-reroutable tunnels, and establishes a tunnel having zero bandwidth indicating the corresponding bandwidth desired for the tunnel. Intermediate nodes send feedback regarding a bandwidth scaling factor for the path, and the head-end node resi...

description In one embodiment, a head-end node determines a path for un-reroutable tunnels, and establishes a tunnel having zero bandwidth indicating the corresponding bandwidth desired for the tunnel. Intermediate nodes send feedback regarding a bandwidth scaling factor for the path, and the head-end node resizes each tunnel accordingly.
