A communication apparatus capable of automatic recognition between remote communication apparatuses using a SSDP packet according to UPnP specification without changing the existing UPnP stack is disclosed. The communication apparatuses connected to communication networks each comprise a data receiver adapted to receive the data from the communication networks, a policy determining unit adapted to set the rule for determining the processing of the data received by the data receiver, a SSDP determining unit for determining the data processing with reference to the policy determining unit, a SSDP packet decapsulation unit adapted to process and decapsulate the encapsulated SSDP packet, a forwarding address list adapted to register the address of the remote communication apparatus, a SSDP packet encapsulation unit for processing and encapsulating the SSDP packet, and a remote apparatus information cache for storing the information of the remote communication apparatus.
