Abstract: The present invention discloses an 802.1X protocol-based multicasting control method. According to the method, an authenticated subscriber intercepts the message while sending a request message for joining in a multicasting group, then obtains the port and MAC address information from the intercepted message, searches corresponding subscriber account information from the authenticated data according to said port and MAC address, then authenticates the subscriber's account number and multicasting IP address, and adds the subscriber to the multicasting group after successful authentication; therefore, controlled multicasting, authentication of the legality of adding to multicasting, and accounting can be achieved according to the method, which can also protect existing investment and compatibility with existing software of the subscriber.

Abstract: A method of implementing handshaking between a network access device and a client includes sending an authentication request message containing the client's address and an appointed multicasting address. The authentication request message is sent from the client to the network access device to authenticate the client. After a successful authentication, the network access device sends handshaking messages at a preset handshaking time interval. When the client receives the handshaking messages, the client sends handshaking response messages to the network access device, also at the preset handshaking time interval. The handshaking messages are an EAP-Request/Identity messages defined in 802.1X, and the handshaking response messages are EAP-Response messages defined in 802.1X. If the network access device or the client does not receive messages from its counterpart for specified times within the handshaking time interval, they perform processing to take the client off line and sending a prompt for reconnection, respectively.
