My main concern lies in the fact that ports need to be opened incoming to the computers using Dragonfly. Relaying through a central server would be much easier to secure since we would know exactly where traffic is going to and coming from; in this scenario shaping would be much easier also. We have a limited budget and therefore very limited bandwidth that needs to be portioned out equitably. Therefore priorities have to be set and bandwidth apportioned properly. P2P has the inherent ability to overwhelm our limited bandwidth rather quickly. So on the priority list it takes a back seat. I would personally love to not have to deal with this, but it is a budgetary reality.

Despite what Dragonfly says it is essentially a P2P application and therefore, in my opinion, should be treated as such.
Suppose Dragonfly wasn't P2P based, and relayed all data through a central server. If it worked that way, and still managed to use all of your bandwidth, what would you do then? I'm not saying you are wrong for shaping this application, just that your justification for doing so seems a bit odd. Dragonfly isn't greedy, it is just efficient. It opens a single tcp connection and sends optimal sized packets. You couldn't ask for a better behaving application. -- -- Justin Azoff -- Network Performance Analyst
