摘要： A multi-radio device system includes a set of sending radio devices and a set of receiving radio devices. Among the sending radio devices is a load-balancing radio device that receives data packets from an originating network. The load-balancing radio device labels data packets with sequence numbers and distributes the labeled data packets among the sending radio devices based on the relative capacities and statuses of those sending radio devices. The sending radio devices transmit the labeled data packets to the receiving radio devices. The receiving radio devices send the labeled data packets to an aggregating radio device within the set of receiving radio devices. The aggregating radio device uses the sequence numbers to ensure that the data packets are forwarded to a destination network in the correct order, extracting original data packets from the labeled data packets before forwarding the original data packets on toward the destination network.

摘要： Radios synchronize their timing mechanisms using a timing signal that those radios propagate from one radio to another. Radios that are close to each other transmit only during times that none of the other nearby radios is trying to receive. In one scheme, a “master” radio initiates communication while another “slave” radio responds in a pre-determined manner. The master generates and propagates an inverted timing signal to the slave, which propagates approximately the same inverted timing signal to other radios in the slave's cluster. Each radio can be in one of three different modes: “source,” “auto,” and “recipient” modes. A “source” radio generates a timing signal independently. A “recipient” radio uses a received timing signal and forwards it to other radios. An “auto” radio behaves as a “recipient” radio while a timing signal is detectable, but behaves as a “source” radio if the timing signal is lost.

摘要： A transmission and updating method and the apparatus thereof for consecutive changing data. The method comprising the steps: the server extracts the data set from the consecutive changing data at the predetermined time interval consecutively (101); the server compares the whole set of the latest data set with the whole set of the prior one in the form of symbol to obtain the changing string; vary the changing string to the changing set (102); transmit the changing set to one or more clients (103) so that the clients can update the data set to the latest data set according to the current data set (104). The method of the present invention divides the data set into several symbols, as the symbol is flexible, an item can be divided into multiple symbols, and the data sets are compared with the symbol as a unit to diminish the compared unit, so the byte length of the obtained changing string is reduced, such that the transmission quantity is reduced greatly, the transmission speed is increased and the requirement for bandwidth is reduced.

摘要： A content delivering method for computer network and system are provided. The present invention classifies nodes participating in content transmission into a transmitting group and a receiving group, and uses the groups to manage the nodes dynamically entering or quitting, and the management includes grouping, monitoring and reflecting update of CDS of group controlling information. Real time management for nodes is achieved through CDS, and the nodes in the transmitting group communicate information according to nodes recorded in the CDS. Multiple nodes in the transmitting group cooperate with each other in transmitting content. Firstly, transmission tasks are assigned to nodes in the transmitting group, and then, nodes in the transmitting group divide assigned content into many blocks and package them and transmit to nodes in the receiving group, and nodes in the receiving group which have received content packages exchange the content packages in the group according to the control data set. Therefore, the content is simultaneously transmitted from a plurality of nodes to other a plurality of nodes, and content transmission speed is improved, compared to the prior art.
