[Idr] draft-van-beijnum-idr-iac-00

Hi,

A while ago I had a short discussion with Robert Raszuk about (the  
lack of) an inter-AS metric, and he asked me to write my idea up in a  
draft. I did. Let me know what you think.

> Abstract:
> Although BGP implementations have extensive path selection
> algorithms, in practice operators have trouble performing
> satisfactory traffic engineering of incoming traffic based on BGP
> attributes that are taken into account in the path selection
> algorithm alone.  For this reason, many ASes deaggregate their
> address range(s) into smaller blocks and announce these blocks
> differently to different neighboring ASes in order to arrive at the
> desired traffic flow.  This practice contributes to the growth of the
> global routing table, which drives up capital expenditures for
> networks engaging in inter-domain routing.  This memo introduces a
> new inter-domain metric that supports finer-grained traffic
> engineering than current BGP attributes, most notably, the AS path.
