Background and Motivations Some MPLS-TE deployments may generate a large number of TE-LSPs E.g. a full mesh of 300 PEs => more than 20 k RSVP sessions per LSR RSVP sessions are quite memory consuming Unfortunately LSR memory is not infinite ? There may be cases where an LSR runs out of memory, or more generally out of a specific control plane resource, and cannot support a new TE-LSP This document defines (G)MPLS-TE routing and signaling extensions for a proper handling of such control plane saturation |
