Local Flash Peer-to-Peer Communication over LAN (without Cirrus/Stratus)

August 27th, 2010

native-ip-multicast-small Some of you guys were probably wondering how to establish P2P connections in the local network (LAN) without Adobe Cirrus. Yes. It’s possible.

In the previous tutorial File Sharing over P2P in Flash Player 10.1 with Object Replication we went through the Object Replication basics. And you can see that the Receiver is requesting packets one by one. That’s not suitable for the real world app, but it’s good for testing on a LAN to see the progress. In the real world app, you can immediately request all packets using NetGroup.addWantObjects(beginIndex, endIndex);.

P2P Video Calls on Android

My fellow evangelist Mark Doherty built a great demo app using P2P and AIR 2.5 for Android. Watch this video, where he shows how it works. And btw: I should really teach him how to pronounce my name :) Mark, you are going to get a lesson at MAX 2010!
