Re: [mpls-tp] [mpls] poll to adopt draft-nitinb-mpls-tp-on-demand-cv as a working group document

[Eric Gray <[e-mail]>]

Haiyan,

	This is largely a semantics issue.

	The extensions described in this draft are intended to - among
other things - support the requirements of a transport profile of 
MPLS.  Those requirements initially drove the creation of this draft.
It is still the case that these extensions are intended to support a
transport profile of MPLS.

	However, as you note, they also support usage in an environment
that may not be strictly limited to "transport" in the sense that has
been used in referring to a "transport profile."  Specifically, in 
cases where (for example) IP addressing may be used generally in the
services being provided by a service provider who also plane to use
similar/identical technology to support "transport" requirements.

	It appears to be the (rough?) consensus of the MPLS working
group that "LSP-Ping" is the tool of choice for on demand CV.  Ping,
in general, has filled a role as on-demand connectivity verification
in IP-based networks for a very long time, and network operators who
plan to use IP infrastructure to support their own "transport" needs
are generally aware of this tool and the on-going need for it in the
IP network infrastrcture.

No/ do not support.

Several comments need clarification: 

1) We do not see how the content of the draft satisfies "on-demand-cv" as claimed in the title. We only see "LSP-Ping" and "LSP Traceroute" in the main part of the draft. 
In the introduction part we also see the "on-demand Connectivity Verification, Route Tracing and Adjacency functions". 
Could the authors clarify the "on-demand CV"? 

2) Could the authors clarify the purpose of describing "LSP-Ping with IP encapsulation" and "LSP Traceroute with IP encapsulation"?

The draft seems to be just a regular extension of MPLS LSP ping, not particular for MPLS-TP. Shouldn't it be a draft with the name "mpls-lsp-ping-extensions"?
