Title : PCE Management Interface
Author(s) : E. Grampin
Filename : draft-grampin-pce-mgmnt-if-00.txt
Pages : 8
Date : 2005-7-5
The Path Computation Element (PCE) Architecture provide a framework
to support the Constraint-Based Routing (CBR) functionality for
traffic engineering systems in Multiprotocol Label Switching (MPLS)
and Generalized Multiprotocol Label Switching (GMPLS) networks.
The model define the PCC and PCE entities at the Control Plane, which
communicate using a Request/Reply protocol.
The PCE architecture enable network operators a tight control of the
resource assignment by means of the administrative constraints that
are included in the Traffic Enginnering Database (TED), and used in
the path computation process. Moreover, appropriate objective
funtions assist operators in the fulfillment of the overall network
objectives.
This document present a system architecture for the PCE, namely
Routing and Management Agent (RMA), with a standard management
interface, which permit established management frameworks to rely on
the PCE for the CBR functionality and inject network-wide policies
into the PCE path computation process. Some reliability issues of the
PCE Architecture are addressed in the document.

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
