RSVP-TE Signaling Extension for Explicit Control of Region Boundary
draft-fuxh-ccamp-boundary-explicit-control-ext-00
Abstract
[draft-fuxh-pce-boundary-explicit-control-framework-00] defines the
framework for explicit control of region boundary in PCE-based inter-
layer architecture. This document defines the RSVP-TE extension for
region boundaries explicit control.

Internet-Draft RSVP-TE for Region Boundary Control March 2010
1. Introduction
[draft-fuxh-pce-boundary-explicit-control-framework-00] defines the
framework for explicit control of region boundary in PCE-based inter-
layer architecture. There is a requirements for RSVP-TE extensions
to support explicit control of region boundary. A new object could
be introduced in RSVP-TE signaling message.
2. ERBO (Explicit Region Boundary Object)
The format of ERBO object is the same as an ERO. The ERBO including
the region boundaries information can be carried in Path message.
3. RSVP-TE Extension
The Pathe message is extended as followings:
<Path Message> ::= <Common Header> [ <INTEGRITY> ]
[ [<MESSAGE_ID_ACK> | <MESSAGE_ID_NACK>] ... ]
[ <MESSAGE_ID> ]
<SESSION> <RSVP_HOP>
<TIME_VALUES>
[ <EXPLICIT_ROUTE> ]
[ < ERBO > ]
<LABEL_REQUEST>
[ <PROTECTION> ]
[ <LABEL_SET> ... ]
[ <SESSION_ATTRIBUTE> ]
[ <NOTIFY_REQUEST> ]
[ <ADMIN_STATUS> ]
[ <POLICY_DATA> ... ]
<sender descriptor>
<sender descriptor> ::= <SENDER_TEMPLATE> <SENDER_TSPEC>
[ <ADSPEC> ]
[ <RECORD_ROUTE> ]
[ <SUGGESTED_LABEL> ]
[ <RECOVERY_LABEL> ]
