The siplex
application has been created for this need. In order to make it seen as "one link connection" from the firewall perspective it's needed that the Caller party use the same outgoing port for UDP packets. From the SRT point of view these are still multiple connections using multiple sockets, just each socket at the Caller side uses the same outgoing port. The socket ID is contained in the SRT header anyway, so the packet directed to particular socket will be always correctly dispatched, no matter at which UDP port it has been received.
This utilizes a feature that existed in UDT before - if you don't preset an outgoing port before calling srt_connect()
, it will be autoselected (as usual), but you can enforce outgoing port by calling srt_bind()
first.
The streamid
feature can be also treated by an application as as kind of "port number extension" - as per service definition, you can serve multiple streams on one port, where particular stream is selected using the stream ID, and you can also request them all to be transmitted simultaneously.
This application is available in dev
branch now.
