Isn't game traffic fairly small in bandwidth need, but very latency dependent? QOS seems like a good fit here. Priority queue the game traffic based on matched ACL, and best effort everything else, re-marking it as necessary. Based on previous years, what are the true bandwidth needs?

Imagine a few more "Players" section scattered around the 2x10G rings. We are already planning for IPV6 but that really depends on our upstream ability to actually provide the feature. Very good point about BCP38, that is not something we had considered. We usually segment the network for each row of tables which usually ends up being 48 players in the same vlan.
