Just one comment. I agree that if the overlay is experiencing very little or no churn at all, the amount of stabilization traffic is rather low. However, based on my experiences of running a P2P overlay in PlanetLab, I would say that if the overlay is churning even at a moderate rate, optimizations like this might well be worth doing. When there is churn, you need to increase the amount of stabilization messages and it is not unusual that a considerable percentage of the total traffic is stabilization traffic. -Jouni _______________________________________________ P2PSIP mailing list [email protected] https://www.ietf.org/mailman/listinfo/p2psip
