Sorry for resending.
The changes in this version have massive impact for CC/CV/RDI implementation.
We, venders, have kept making efforts on interoperability test again and again.
These changes spoil this effort.
Especially, revival of Poll/Final sequence doesn't make sense.
Originally, in my understanding, Poll/Final sequence was excluded from this
to avoid making HW implementation difficult.
Even though it was difficult to change CC interval arbitrary,
the problem should be solved by defining how to transit DOWN/INIT state to UP
The direction which reached consensus once should NOT be changed easily
in order to respond to the market requirements.
IMO, such major changes should NOT be added right before becoming RFC.
I found at least four major/minor changes as follows;
1)Revival of Poll/Final sequence
2)Change of MEP ID formats
3)Change of Diag. Code
4)Change of CV interleaved definition
The IESG has received a request from the Multiprotocol Label Switching WG
(mpls) to consider the following document:
- 'Proactive Connectivity Verification, Continuity Check and Remote
Defect indication for MPLS Transport Profile'
<draft-ietf-mpls-tp-cc-cv-rdi-05.txt> as a Proposed Standard
The IESG plans to make a decision in the next few weeks, and solicits
final comments on this action. Please send substantive comments to the
ietf(_at_)ietf(_dot_)org mailing lists by 2011-07-14. Exceptionally, comments
sent to iesg(_at_)ietf(_dot_)org instead. In either case, please retain the
beginning of the Subject line to allow automated sorting.
Continuity Check, Proactive Connectivity Verification and Remote
Defect Indication functionalities are required for MPLS-TP OAM.
Continuity Check monitors the integrity of the continuity of the
label switched path for any loss of continuity defect. Connectivity
verification monitors the integrity of the routing of the label
switched path between sink and source for any connectivity issues.
Remote defect indication enables an End Point to report, to its
associated End Point, a fault or defect condition that it detects on
a pseudo wire, label switched path or Section.
This document specifies methods for proactive continuity check,
continuity verification, and remote defect indication for MPLS-TP
label switched paths, pseudo wires and Sections using Bidirectional
