A requester multicasts a service command. When a service receives the service command, it performs the operation that is specified by the service command, which may generate response data. The service may then send, and the requestor may receive, a response message via unicast. The response message may include the response data. The response message may also include discovery information about the service, which is information that facilitates discovery of the service by the requestor. The requestor processes the response data and the discovery information. If further interaction with the service is desired, the requester may use the discovery information to establish a connection with the service.
