Message queue

Handles message passing between the network coordinator and the different network participants. Usually a standards-based message queue implementation like RabbitMQ.

Network coordinator

The MsgFlo network coordinator is a software process responsible for keeping track of network participants, and assigning communications channels (message queues) between the different participants.

It also serves as a FBP protocol endpoint for clients like Flowhub and proxying the protocol to the clients as needed.

Network participant

MsgFlo Network Participant is a software process that makes itself available to the network. In FBP terms it may provide a single or multiple FBP network processes based on what things it is actually running. Participants are typically FBP runtimes instances.
