Lookup service system in JINI-based home network supporting IEEE1394 and TCP/IP

摘要

In a lookup service system in a JINI-based home network supporting both IEEE1394 and TCP/IP, a service provider proxy DB stores proxy information of TCP/IP-based and IEEE1394-based service providers registered for a lookup service (LUS). A stream link channel handler (SLCH) performs a channeling of data transmitted/received between IEEE1394-based and TCP/IP network-based devices. An IEEE1394 event manager included in an event manager of the LUS dynamically reconfigures IEEE1394-based service information and manages changes of an IEEE1394 network state. An IEEE1394 bus manager receives IEEE1394 network events redefined by an IEEE1394 event manager and maintains and updates an IEEE1394 network topology and a GUID map.
