Hi Kevin,

thanks for your reply.

I thought he meant something like APNS/GCM, that's why I replied like this.

Tsung provides you with the basic things you need to generate load depending on your use case. Of course I didn't mean to just use it with the most basic configuration. 

>> Message reliability is very important (as said previously). Also you'll need an XMPP library which is robust. There's e.g. asmack[3] for Android and e.g. XMPPFramework[4] for iOS.

Could you please elaborate on this? As I was searching for libraries I couldn't find a lot more than those.
