Sent messages will be scheduled among the endpoints according to socket type: PUB will send the same data to all endpoints simultaneously, PUSH will do round robin transfer. Incoming data is fair queued between endpoints. This is a feature of at least zeromq and nanomsg. _____________ To use: in the device configuration, instead of specifying just one address, specify a comma separated list e.g. tcp://localhost:123,ipc:///tmp/socket the connection method (bind/connect) applies to all endpoints in this case. ______________ Mixing binding and connecting endpoints is supported: prefix "@" means "bind", "+" (or ">") means connect, e.g. +tcp://localhost:123,@ipc:///tmp/socket,ipc:///tmp/asd (in case of missing prefix, the default channel method is used for that endpoint).
