Re: C&W Peering Problem?

["Christopher A. Woodfield" <rekoil () semihuman com>]

It seems as if a good solution to this kind of an imbalance would be for 
the peering partners to agree to listen to each others' MEDs. That way 
access provider B gets the traffic handed to them a close to the 
destination as possible. True, that means they need a beefier backbone, 
but the value in the peering arrangements they don't lose as a result 
of imbalanced traffic would seem to compensate. Are there any known 
iplementations like this among backbone providers?
