Technical Summary
OLSRv2 includes the ablity to assign metrics to links and to use
those metrics to allow routing by other than minimum hop count
routes. This document provides a historic record of the rationale
for and design considerations behind how link metrics were included
in OLSRv2.
Working Group Summary
o OLSRv2 was first submitted as an individual draft in July 2005
(draft-clausen-manet-olsrv2-00), and accepted as a Working Group
document in August 2005.
o OLSRv2 is in the process of approval as a Proposed Standard.
o A key difference between RFC3626 and OLSRv2 is the introduction
of support for link metrics. An individual draft (draft-dearlove-olsrv2-
metrics-00) was submitted in 2007, discussing the design options,
culminating in 2010 with draft-dearlove-olsrv2-metrics-05
documenting Working Group consensus on this matter. Metrics
support was, then, folded into OLSRv2.
o This document retains and documents the design rationale, and
important decisions for how metrics were integrated into OLSRv2.
Thus, this document reflects WG consensus built up during the evolution
of OLSRv2, and records the consensus view that lies behind OLSRv2.
Document Quality
There is a number of independent implementations of OLSRv2, as was
indicated in the write-up for that I-D.
This document does not propose a protocol, or mandate protocol behavior,
but rather presents part of the design rationale for OLSRv2.
