> If you do not use caches in your ILA-Ns (and yes, I understand your reasoning for not doing so), then you are constructing an overlay network.  One of the arguments I was given for using ILA was to enable direct forwarding of packets effectively without needing to have routing track the moving entities.  Without caches, you are pushing all the traffic through fewer entities.  And you seem to be either using a lot of ILA-R with concomitant information distribution or few ILA-R restricting the information distribution problem but instead having traffic concentration problems.

As well as suboptimal paths.
