Dear WG, Just to let you know that a new ID has been posted proposing a simple
extension to the ERO to allow path segments in separate ASs to remain
confidential. There are indeed various circumstances that require "encoding"
a path segment in some form. I've included the abstract below. Note that this
ID may eventually be split to be discussed separately in CCAMP and PCE but we
prefer to start with a single ID first to be discussed in CCAMP. Comments are very welcome. Thanks, Rich Subject:

[EMAIL PROTECTED] A New Internet-Draft is available from the on-line Internet-Drafts
directories. Title :
Protocol Extensions for Signaling
Confidential
Path Segments in Multiprotocol
Label
Switching Traffic Engineering. Author(s) :
R. Bradford, et al. Filename :
draft-rbradfor-ccamp-confidential-segment-00.txt Pages : Date :
2006-3-1 Routes for Multiprotocol Label Switching (MPLS) Label Switched Paths (LSPs) may be computed by Path Computation Elements (PCEs). Where the LSP crosses multiple domains such as Autonomous Systems (ASs) the path may be computed by multiple PCEs that cooperate, with each responsible for computing a segment of the path. However, in some cases such as when ASs are administered by separate Service Providers, it would break confidentiality rules for a PCE to supply a path segment to a PCE in another domain. This issue may be circumvented by returning a loose hop and by invoking a new path computation from the domain boundary LSR during LSP setup as the LSP enters the second domain, but this technique has several issues including the problem of maintaining path diversity. This document allows a PCE to provide a full path, but to hide the contents of a segment of that path called the Confidential Path Segment (CPS). The CPS may be conveyed in the PCE Communication Protocol (PCEP) and signaled in a Resource Reservation Protocol (RSVP) explicit route either by replacing it with a path key or by encrypting it.

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.
