Re: [Roll] I-D Action: draft-ietf-roll-p2p-measurement-05.txt

This version takes care of ticket #98 (created in response to LC comment by Phil Levis) and has the following changes:

1) Updated the overview section. This section now has better explanation of the mechanism and explicitly clarifies the following:
1.1) The route being measured is from the origin to the target.
1.2) The origin decides what metrics are measured.

2) Section 4 (Originating a Measurement Request) now clearly says:

"The Origin MUST also include the routing metric objects of
   interest inside one or more Metric Container options inside the MO.
"

3) Section 5 (Processing a Measurement Request at an Intermediate Router) now clearly says:

"An Intermediate Router can
   only update the existing metric objects and MUST NOT add any new
   routing metric object to the Metric Container.  An Intermediate
   Router MUST drop the MO if it cannot update a routing metric object
   specified inside the Metric Container."

4) Updated the IANA section to include the correct language as per RFC5226.

These modifications should remove the perceived ambiguity (regarding who decides which metrics would be measured) reported in Ticket #98. 

Thanks

A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Routing Over Low power and Lossy networks Working Group of the IETF.

	Title           : A Mechanism to Measure the Quality of a Point-to-point Route in a Low Power and Lossy Network

   This document specifies a mechanism that enables an RPL router to
   measure the quality of an existing route towards another RPL router
   in a low power and lossy network, thereby allowing the router to
   decide if it wants to initiate the discovery of a better route.
