Abstract
Techniques are describe for establishing an overall label switched path (LSP) for load balancing network traffic being sent across a network using the a resource reservation protocol such as Resource Reservation Protocol with Traffic Engineering (RSVP-TE). The techniques include extensions to the RSVP-TE protocol that enable a router to send Path messages for establishing a tunnel that includes a plurality of sub-paths for the overall LSP. The tunnel may comprise a single RSVP-TE Label Switched Path (LSP) that is configured to load balance network traffic across different sub-paths of the RSVP-TE LSP over the network.
