Low-Latency Peer To Peer Topology With Dynamic Rerouting

JoinFS can monitor and detect any connectivity problems and will automatically reroute network data in order to maintain the integrity of the session and consequently bypasses issues with NAT home routers.

JoinFS Peer To Peer Network

Decentralized Public Server Network

In hub mode the server details are propagated automatically across the client network. There is no central server.

On The Horizon

Record, Play and Overdub

JoinFS includes its own flight recorder. This enables you to record your aircraft along with other pilots in the JoinFS network. When you play back a recording the aircraft are also broadcast over the network so that all pilots can see your recording. This allows you to pre-record a lead aircraft which everyone in the session can then formate on. The overdub feature enables you to overlay new flights onto the recording which means you can iteratively build your own unlimited formation.
