摘要： An access point, a layer 2 switch, and multicast handover supporting method using the access point and the layer 2 switch are provided. According to the method of supporting multicast handover, when a mobile node is handed over from one cell to another while being provided with a multicast service in a wireless mobile communication network, the L2 switch performs multicast traffic routing in response to reception of MAC address information and multicast service source and group information from the access point. Hence, multicast traffic can be supported to be fast and seamlessly handed over within layer 2 network equipment.

摘要： An Internet broadcasting system and a method thereof are provided. The Internet broadcasting system includes: a signal converter for converting a received analog broadcasting signal into a digital broadcasting data; an Internet broadcasting unit for storing and sending the digital broadcasting data; a repeater for relaying the digital broadcasting data to a switching unit connected with a terminal according to a broadcasting request message inputted from the terminal but selectively relaying a channel selected by the terminal by referring to a first multicasting forwarding table created by using a UDP port number extracted from the broadcasting request message; and the switching unit for snooping on the broadcasting request message, extracting the UDP port number, storing the extracted UDP port number into a second multicasting forwarding table, and transmitting the digital broadcasting data of the selected channel to the corresponding terminal referring to an entry of the second multicasting forwarding table.
