Abstract:
Stateful PCE (Path Computation Element) and its corresponding
protocol extensions provide a mechanism that enables PCE to do
stateful control of MPLS Traffic Engineering Label Switched Paths (TE
LSP). One application that stateful PCE can realize is data traffic
reoptimization. Data traffic traversed in a LSP can be switched to
another PCE-initiated LSP. Moreover, data traffic can also be
balanced to multiple PCE-initiated LSPs using stateful PCE.
This document specifies the extensions to Path Computation Element
Protocol (PCEP) that allow a stateful PCE to do switchover and
balancing of data traffic with PCE-initiated LSPs. This document
also specifies the usage and handling of stateful PCEP (PCE
Communication Protocol) messages and the expected behavior of PCC as
the RSVP-TE headend.
