Abstract
Provided is a home network connection management system using UPnP (Universal Plug and Play) and VLAN (Virtual LAN) multicast. The home network connection management system includes a UPnP-VLAN interfacing section 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 section for registering the VLAN and multicast addresses in a VLAN mapping table according to connection establishment request from the UPnP device through the UPnP-VLAN interfacing section, the VLAN mapping table for matching and storing the VLAN and multicast addresses under the control of the VLAN managing section, and an Ethernet device driver for retrieving the VLAN and multicast addresses from the VLAN mapping table in response to TCP/IP data from an outside, forming the received TCP/IP data into VLAN frames, and transmitting the VLAN frames.
