Title : A set of monitoring tools for Path Computation Element based Architecture
Author(s) : J. Vasseur
Filename : draft-vasseur-pce-monitoring-01.txt
Pages : 16
Date : 2006-10-19
A Path Computation Element (PCE) based architecture has been
specified for the computation of Traffic Engineering (TE) Label
Switched Paths (LSPs) in Multiprotocol Label Switching (MPLS) and
Generalized MPLS (GMPLS) networks in the context of single or
multiple domains (where a domain is referred to as a collection of
network elements within a common sphere of address management or path
computational responsibility such as IGP areas and Autonomous
Systems). In such PCE-based environment it is thus critical to
monitor the state of the path computation chain and potentially
gather various performance metrics with regards to the set of
involved PCE(s) that can be used for performance monitoring and
troubleshooting purposes. This document specifies procedures and
extensions to the Path Computation Element Protocol (PCEP) in order
to gather such information.

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
Internet-Draft.
