Link Metrics for the Mobile Ad Hoc Network (MANET) Routing Protocol
OLSRv2 - Rationale
draft-ietf-manet-olsrv2-metrics-rationale-04
Abstract
OLSRv2 includes the ability 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.
