Abstract:
In one embodiment, an intermediate node computes paths for a set of tunnels that do not include a particular link (e.g., and possibly a scaled-down bandwidth for each tunnel), considering all of the tunnels of the set. The intermediate node informs head-end nodes of the tunnels of the computed paths (e.g., and scaled bandwidth) and/or a time to reroute the tunnels.
