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