Patent ID: 7869433

Claim:
A home network connection management system using Universal Plug and Play (UPnP) and Virtual LAN (VLAN) multicast, comprising: a UPnP-VLAN interfacing unit for receiving requests of registration of VLAN and multicast addresses from a UPnP device in response to connection establishment commands from a connection manager; a VLAN managing unit for registering a VLAN ID and a multicast IP group address in a VLAN mapping table based on connection establishment requests provided from the UPnP device through the UPnP-VLAN interfacing unit; the VLAN mapping table for matching and storing the VLAN ID and multicast IP group address under the control of the VLAN managing unit; an Ethernet device driving unit for retrieving the VLAN ID and multicast IP group address from the VLAN mapping table in response to receipt of Transmission Control protocol/Internet Protocol (TCP/IP) data sent from a server, forming the received TCP/IP data into VLAN frames, and transmitting the VLAN frames, and a Generic Attribute Registration Protocol (GARP) processing unit for dynamically registering/releasing a VLAN ID and multicast IP group addresses in/from an adjacent switch using GARP when the portion of adjacent nodes within the home network do not support UPnP.
