The Path Computation Element (PCE) is a network component,
application, or node that is capable of performing path computations
at the request of Path Computation Clients (PCCs). The PCE is
applied in Multiprotocol Label Switching Traffic Engineering
(MPLS-TE) networks and in Generalized MPLS (GMPLS) networks to
determine the routes of Label Switched Paths (LSPs) through the
network. The Path Computation Element Communication Protocol (PCEP)
is specified for communications between PCCs and PCEs, and between
cooperating PCEs.
When computing or re-optimizing the routes of a set of LSPs through a
network it may be advantageous to perform bulk path computations in
order to avoid blocking problems and to achieve more optimal network-
wide solutions. Such bulk optimization is termed Global Concurrent
Optimization.
This document provides application-specific requirements and the PCEP
extensions in support of a global concurrent path computation
application.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
