Protocol Action: 'A Per-domain path computation method for establishing Inter-domain Traffic Engineering (TE) Label Switched Paths (LSPs)' to Proposed Standard
The IESG has approved the following document:
- 'A Per-domain path computation method for establishing Inter-domain
Traffic Engineering (TE) Label Switched Paths (LSPs) '
<draft-ietf-ccamp-inter-domain-pd-path-comp-06.txt> as a Proposed Standard
This document is the product of the Common Control and Measurement Plane
Working Group.
The IESG contact persons are Ross Callon and David Ward.

Technical Summary
This document specifies a per-domain path computation technique for
establishing inter-domain Traffic Engineering (TE) Multiprotocol
Label Switching (MPLS) and Generalized MPLS (GMPLS) Label Switched
Paths (LSPs). In this document a domain refers to a collection of
network elements within a common sphere of address management or path
computational responsibility such as IGP areas and Autonomous
Systems.
Per-domain computation applies where the full path of an inter-domain
TE LSP cannot be or is not determined at the ingress node of the TE
LSP, and is not signaled across domain boundaries. This is most
likely to arise owing to TE visibility limitations. The signaling
message indicates the destination and nodes up to the next domain
boundary. It may also indicate further domain boundaries or domain
identifiers. The path through each domain, possibly including the
choice of exit point from the domain, must be determined within
the domain.
Working Group Summary
no dissent reported. There are other possible choices for inter-AS or
inter-domain path computation (such as PCE). This document describes
one choice.
Protocol Quality
Ross Callon reviewed the spec for the IESG. Adrian Farrel and Deborah
Brungard (WG co-chairs) have also both reviewed the spec.
