Abstract: A cloud agent device including, determines whether the size of the file is less than the size of the remaining capacity of the second cloud storage, validating the verification request information of correctness, sending a affirmative notification to the first cloud storage and transfer the file from the first cloud storage to the second cloud storage when the verification request information is correct. The invention also provides a cloud storage and a file transferring method. The cloud agent device, cloud storage and file transferring method can efficient and accurate transfer of files in a safe condition.

Abstract: In a method for processing video data of a number of clients of a video conference, the clients include one master client and one or more branch clients. The video data is received from the clients and the received video data of the branch clients are copied. The copied video data of the branch clients are transmitted to the master client, decoded by corresponding CODEC boxes in an array decoder box, and displayed on corresponding screens of a TV wall. The video data of the clients are transmitted to a multipoint control unit, and synthesized by the multipoint control unit to obtain synthesized video data. The synthesized video data is transmitted to each branch client, decoded by a CODEC box of the branch client, and displayed on a display device connected to the branch client.

Abstract: A network access device (10) for using in a mobile communication system includes a receiving module (100), a parsing module (110), a determining module (120), a storage module (130), and a sending module (140). The receiving module receives a packet, and the packet includes a source address and a destination address. The parsing module connected to the receiving module parses the packet to retrieve the source address and the destination address of the packet. The determining module connected to the parsing module determines whether a source of the packet has been authenticated. The storage module connected to the determining module saves notification messages indicating that the source of the packet has been authenticated. The sending module sends the packet to a destination corresponding to the destination address of the packet when the source of the packet has been authenticated.

Abstract: A system for setting network parameters is provided. The system is arranged in a network device connected to a client, and includes a detecting module, a packet determining module, a transmission module, and a parameter setting module. The detecting module detects packets from the client at a port. The packet determining module determines types of the packets, the types of the packet including a SET packet. The transmission module transmits corresponding response packets to the client according to the types of the packet. The parameter setting module sets network parameters of the network device and the client according to the SET packet. A method for setting network parameters is also provided.
