Re: Why doesn't BGP...

From: Vadim Antonov <avg () pluris com> Regarding BGP metrics -- there's a problem with a single "universal" metric in an exterior routing protocol, namely the absense of a single authority to assign those metrics. Different networks may have very much confiliciting interests in how to assign BGP metrics.
Wasn't there a draft somewhere along the way on a global guidelines on how to set the metrics?
Some time ago i wrote a draft (which didn't get any support and quietly expired) regarding BGP metrics -- the idea was to have a vector of metrics (one per AS hop) instead of a single scalar metric; and allow network operators to calculate weighted sums to obtain the locally significant scalar metrics. I.e. a network operator may decide for himself how to interpret BGP metrics coming from different AS-es (or by different paths).
Yeah, I seem to remember liking that. You mean that Tony and Yakov didn't support it.... ;-) And some of the other ideas were similar to Nimrod policy selection....
If there's any interest i can dig the draft out and place it on my www server.
