Abstract:
1. A lookup service system in a JINI-based home network supporting both IEEE1394 and TCP/IP, the system comprising: a plurality of network based devices; a lookup service module stored on said plurality of network based devices, the lookup service module further comprising: a service provider proxy DB for storing proxy information of TCP/IP-based and IEEE1394-based service providers registered for a lookup service (LUS); a stream link channel handler (SLCH) for performing a channeling of data transmitted/received between IEEE1394-based and TCP/IP network-based devices; an IEEE1394 event manager, which is included in an event manager of the LUS, for dynamically reconfiguring IEEE1394-based service information and managing changes of an IEEE1394 network state; and an IEEE1394 bus manager for receiving an IEEE1394 network event redefined by the IEEE1394 event manager and maintaining and updating an IEEE1394 network topology and a GUID map wherein the lookup service system further comprises a universal service ID generation unit for generating a service ID of random 128 bit number on a device basis in order to recognize TCP/IP-based and IEEE1394-based devices connected to the home network, wherein the service ID corresponding to an IEEE1394 based service is based on a time of instigation together with the IEEE 1394 GUID, and the service ID corresponding to TCP/IP-based service is based on a time of instigation together with the a host address.
