Federate Message + Communication Configuration

• Endpoint Federates
• Combination Federation
• Combination Federation with Native HELICS Filters
• Combination Federation with Custom Filter Federates

In the Base Example, we saw information passed between two federates using publications and subscriptions (pubs/subs). In addition to pubs/subs, where information is passed as values (physical parameters of the system), federates can also pass information between endpoints, where this information is now a message.

This section on message and communication configuration will walk through how to set up two federates to pass messages using endpoints, and how to set up three federates which pass between them values and messages with a combination of the two configurations. It will also demonstrate how to use native HELICS filters and how to set up a custom filter federate to act on messages in-flight between federates.
