Abstract
Variable preemption for label-switched paths (LSP) tunnels includes provisioning a label-switched path (LSP) tunnel at a first bandwidth with a first priority value; and provisioning one or more different priority values at one or more of (1) corresponding one or more bandwidths such that a current priority value of the LSP tunnel is set based on a current bandwidth value of the LSP tunnel and (2) redial failure attempts such that the current priority value of the LSP tunnel is set based on a number of the redial failure attempts. The priority values can include one of a Setup Priority, a Holding Priority, and a combination thereof. The one of the Setup Priority, the Holding Priority, and the combination thereof can be based on RFC 3209.
