Ballot Text

Technical Summary

   This document specifies an directional airtime link 
   metric for usage in OLSRv2.  A major shortcoming of 
   OLSR was the use of hop count as a routing metric for 
   MANET networks, which can have highly variable and 
   heterogeneous link properties.  OLSRv2 integrates the 
   concept of link metrics directly into the core specification 
   but the calculation and/or acquisition of this dimensionless 
   additive link cost is not specified.  

Working Group Summary

  There were no working group issues with any specific points.  

Document Quality

   There are at least 3 different independent implementations.  
   Most OLSRv2 implementation authors have either implemented 
   this draft or at least voiced the desire to do so.
