Local Flash Peer-to-Peer Communication over LAN (without Stratus)
August 27th, 2010
Some of you guys were probably wondering how to establish P2P connections in the local network (LAN) without Stratus. Yes. It’s possible. Using native IP-only multicast. Let’s build a simple chat with Posting. Adding Multicast broadcast is just a simple next step which I am sure you can accomplish by yourself with few hints from my article about Multicast
Open an IP Multicast connection. This can be done by specifying connection string as “rtmpf:”. Note, that this technique cannot be used for one-to-one communication. So no DIRECT_CONNECTIONS with NetStream, but you can do all RTMFP Group operations.
netConnection.connect("rtmfp:");

Video-on-Demand over P2P in Flash Player 10.1 with Object Replication
July 28th, 2010
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);.
Transferring VoD video over P2P
Let’s get something real with Object Replication. The use-case I like most is a Realtime P2P Distributed System for Video-on-Demand.

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!

File Sharing over P2P in Flash Player 10.1 with Object Replication

Object Replication
Object Replication is the most lowest-level P2P access available in Flash Player 10.1 (followed by Multicast, Posting and Directed Routing). It basically enables you to send chunks of data between peers. Object Replication is the only P2P access method that guarantees that all data will be transferred to all receiving peers.
Demo
I’ve built this simple file sharing application, which basically loads a file and then you start sharing it. Open another client to start receiving the file.
