Abstract
Techniques are described for varying a bandwidth constraint at one or more hops along a path of a sub-label-switched path (sub-LSP) of a multi-path label-switched path (MP-LSP). The techniques include computing, by an ingress router, a plurality of paths for a plurality of sub-LSPs of a MP-LSP and outputting, by the ingress router, for each path of the plurality of paths, a respective resource reservation request message to establish a respective sub-LSP of the plurality of sub-LSPs, each respective resource reservation request message including an indication of an explicit route, a tunnel identifier indicating the MP-LSP, an identifier for the respective sub-LSP, an indication of a per-hop bandwidth constraint that corresponds to a respective incoming per-hop bandwidth constraint of the plurality of incoming per-hop bandwidth constraints, and one or more instructions to modify the indication of the per-hop bandwidth constraint.
