When path computation is done in the management systems for Layer 1
Virtual Private Networks (L1 VPNs), it would be important that
resource information is synchronized between the management systems
and the Provider Edge /Provider (PE/P). This draft looks at such a
scenario from the viewpoint of the Path Computation Element Metric
Protocol (PCEMP) that acts a generic computation model for path
based metrics in large multi-domain or multi-layer networks. This
draft shows how PCEMP messages might help preserving the path
computational entities in the L1 VPN peer nodes.
This draft proposes to show how a L1 VPN framework may be included
within the scope of Path Computation Element architectures and is
derived primarily from the motivation of per VPN peer service
solutions using PCE techniques. PCEMP metrics defining path quality
measurement criteria, algorithm complexity and scalability criteria
for L1 VPNs is in line with the functional specifications of
Generalized Traffic Engineered LSP path computation techniques
involving Path Computation Element(s) of the PCE WG Charter.

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
