P2P for mobile devices
- 1. P2P for Mobile Devices Immanuel Noel | Platform Evangelist, Adobe blog.inoel.in
- 3. What ? P2P – File sharing? Distributed application architecture Live, Real Time connectivity for devices Flash Platform support
- 4. Why ? • Scalability • Network Efficiency • Secure • Cloud Sourcing Information • Better User Experience • Take advantage of P2P capabilities of AIR for Mobile
- 5. Where ? Everything from application-level video multicasting to swarming file delivery and multiuser games without a server ! Corporate enterprise, social media, and entertainment applications
- 6. Demos Link on the last slide
- 7. The Entities Peer RTMFP Group – Super Set of neighbors Neighbors – Directly connected peers
- 8. How ? Group RTMFP Capable Server
- 9. Infrastructure • FMS Server rtmfp://<SERVER> • Cirrus service (non-commercial), rtmfp://p2p.rtmfp.net/ + DEVELOPER+KEY • Isolated LAN rtmfp://
- 10. Why connect to a external server? • Facilitate connectivity • Directory of connected devices • Authenticity • Manage topology • Self managed P2P groups – No Manual Peer ID Exchange
- 11. Real Time Media Flow Protocol • Protocol • Enables Live, Real time connectivity • Not File Sharing, Best for streaming • Unlike RTMP, based on the UDP protocol • Rapid Connection Restore • IP Mobility • 128-bit AES encryption
- 12. Routing Multicast Many to Many Directed Routing One to Many Object Replication Best effort techniques to transfer large data
- 13. Group Specifier • Define a P2P group • Specify capabilities – Multicast – ipMulticastMemberUpdatesEnabled – MulticastEnabled – RoutingEnabled – PostingEnabled – ObjectReplicationEnabled, and more ! (Group Name + Group Capabilities) = Group Identifier
- 14. Events NetConnection.Connect.Success NetGroup.Connect.Success NetGroup.Neighbor.Connect netGroup.sendToNeighbor(data) NetGroup.SendTo.Notify (event.info.message)
- 15. NetStream - Audio and Video Sender var camera:Camera = Camera.getCamera(); var mic:Microphone = Microphone.getMicrophone(); _outgoingStream.attachAudio(mic); _outgoingStream.attachCamera(camera); _outgoingStream.publish( "P2PVideo" ); Listener NetGroup.MulticastStream.PublishNotify Receiver _incomingStream.play("P2PVideo");
