zcm 1.0.0

A lightweight component model using ZeroMQ

  • ZCM is a lightweight component model using ZeroMQ (http://zeromq.org/)
  • Components are the building blocks of an application
  • Components are characterized by ports and timers.
  • Timers are bound to an operation and fire periodically
  • There are four basic types of ports in ZCM: publisher, subscriber, client and server
  • Publishers publish messages and Subscribers receive messages
  • Clients request the services of a server by sending a request message; Servers receive such requests, process the requests, and respond back to the Client. Until the Server responds, the Client port blocks
  • A Component can be instantiated multiple times in an application with different port configurations
  • A component has a single operation queue that handles timer triggers and receives messages
  • A component has an executor thread that processes this operation queue
  • Components register functionality e.g. timer_operations, subscribers_operations etc.
  • Component instances are grouped together into a process, called Actor
  • An actor receives a configuration (.JSON) file, that contains information regarding the components to instantiate
  • This configuration file also contains properties of all timers and ports contained by the component instances
