PCEP Extension for Explicit Control of Region Boundary in PCE-Based
Inter-Layer Architecture
draft-fuxh-pce-boundary-explicit-control-pcep-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 PCEP 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 PCEP extensions to
support explicit control of region boundary. A new object could be
introduced in PCEP 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 PCEP message.
3. RSVP-TE Extension
The PCEP message is extended as followings:
<PCRep Message>::=<Common Header>
<response-list>
<response-list>::=<response>[<response-list>]
<response>::=<RP>
[<NO-PATH>]
[<attribute-list>]
[<path-list>]
<path-list>::=<path>[<path-list>]
<path>::= <ERO>[<ERBO>]<attribute-list>
<attribute-list>::=[<LSPA>] [<BANDWIDTH>] [<metric-list>] [<IRO>] <metric-list>::=<METRIC>[<metric-list>]
4. Security Considerations
TBD
5. IANA Considerations
TBD
