What ?P2P – File sharing?Distributed application architectureLive, Real Time connectivity for devicesFlash Platform support

Why ?• Scalability• Network Efficiency• Secure• Cloud Sourcing Information• Better User Experience• Take advantage of P2P capabilities of AIR for Mobile

Where ?Everything from application-level videomulticasting to swarming file delivery andmultiuser games without a server !Corporate enterprise, social media, andentertainment applications

DemosLink on the last slide

The EntitiesPeerRTMFPGroup – Super Set of neighborsNeighbors – Directly connected peers

How ? GroupRTMFP Capable Server

Infrastructure• FMS Server rtmfp://<SERVER>• Cirrus service (non-commercial), rtmfp://p2p.rtmfp.net/ + DEVELOPER+KEY• Isolated LAN rtmfp://

Why connect to a external server?• Facilitate connectivity• Directory of connected devices• Authenticity• Manage topology• Self managed P2P groups – No Manual Peer ID Exchange

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

Routing Multicast Many to Many Directed Routing One to Many Object ReplicationBest effort techniques to transfer large data

Group Specifier• Define a P2P group• Specify capabilities – Multicast – ipMulticastMemberUpdatesEnabled – MulticastEnabled – RoutingEnabled – PostingEnabled – ObjectReplicationEnabled, and more ! (Group Name + Group Capabilities) = Group Identifier
