Rationale for the Use of Link Metrics
in the Optimized Link State Routing Protocol Version 2 (OLSRv2)
Abstract
The Optimized Link State Routing Protocol version 2 (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.
