MPLS includes the concept of pre-emption where, for administrative reasons such as contention for system resources, a new Label Switched Path (LSP) may displace an existing LSP. This document clarifies the procedures for MPLS pre-emption in the light of implementation experience. The procedures in this document update those described in RFC 2205 and RFC 3209, but apply only to RSVP-TE used in the MPLS context.}, }
