# Manager-Engine and Driver-Manager Communication

All communication between Engines and Managers (Directors and Brokers) and between Drivers and Managers uses the HTTP protocol. The Engine or Driver acts as HTTP client and the Manager acts as HTTP server.

All communication between Engines and Managers or Drivers and Managers is with the HTTP protocol on the port assigned when the Manager is installed. In this diagram we assume the assigned port is 8080. All HTTP communication is initiated by the Engine or Driver as the HTTP client.

An Engine Daemon periodically checks if its IP address has changed. If so, the Engine Daemon restarts itself and all Engine instances so that they use the new IP address.
