Overview

The OpenHiva also supports service-based communication. Figure 1 shows the communication mechanism.

Figure 1 Service-based communication principle

Service-based invoking is another communication method of the OpenHiva framework. When the client (OpenHiva::ServiceClient) sends a request, the server (OpenHiva::ServiceServer) invokes the registered callback function to process the request, then, a response is made and the result is returned to the client. In this way, a request-response process is complete. Different from topic-based communication, service-based communication is bidirectional and implements one-to-one communication.
