Systems and methods for preemption of Traffic Engineering LSPs such that preemption decisions are made in a coordinated fashion along the path of a new LSP and computation of a new path for a preempted LSP can take advantage of knowledge of newly unavailable links.

The speculation is ascertained by parallelly performing reachability test and duplicate address detection, if necessary. The reachability test is done in a unicast manner so as to conserve wireless link bandwidth.
