Abstract
Disclosed is a communication network system in a bus network structure and a data transmitting/receiving method, the system including: a broker processing a message routing; a connector; and a plurality of services connected to the broker via the connector, wherein: the service is a communicable terminal node and a network address identifying each service is allocated to the each service, the connector is a module for mediating a connection between the service and the broker, and the broker is a module for setting up a routing path or a connection with the connector to process the message routing, all brokers connected to each other in a full mesh topology.
Claims23
A communication network system comprising one or more servers to provide services in a network, the system comprising:
- a plurality of connector devices coupled to one or more broker devices, the broker devices connected in a mesh network topology and each of the servers is connected to each of the broker devices in a bus network topology, and the connector devices configured to receive one or more service instances from a plurality of service terminal nodes, each service terminal node comprising a unicast network address corresponding to the one or more service instances, the unicast network address comprising a server identification (ID) and a service instance ID, the server ID identifying a server activating a particular service, and the service instance ID uniquely identifying a corresponding service in an associated server,
