Using link congestion to control routing updates

[David Scott Olverson <olverson () fas harvard edu>]

Hello all,

        I was wondering if anyone was aware of a way to use the congestion
of a network link to control the routing update.  For example if I have a
very small link that gets congested, I may want the router to withhold a
routing update until link congestion falls below a certain threshold like
60% of bandwidth.  Is anyone aware of anything like this available today
or a technique that might accomplish something similar?  You can contact
me off list if this topic isn't germane.

Thanks for your help,

Dave Olverson
