The invention discloses a method for automatically switching a communication channel, aiming at solving the problems that the transmission efficiency of the existing emergency rescue command system in the single communication channel is seriously limited by the working state of the communication channel, and a worker can not easily select the optimal communication channel mode from multiple communication channels. The method comprises the following steps of firstly evaluating the transmission quality of the plurality of available communication channels to generate an evaluation result; determining the optimal communication channel according to the evaluation result; if information data need to be received and transmitted, automatically switching the optimal communication channel by a working channel; and giving the network parameters of the working channel to computers of the receiving part and the transmitting part to establish the communication link between the information receiving part and the information transmitting part. A cache device is also added into the method, and is used for carrying out breakpoint recording on the information data when a network is temporarily disconnected and carrying out breakpoint resume on the information data when the network is connected again; and after the transceiving process is finished once, the information data of the this time in the cache device are deleted.

The invention discloses a method for sampling and scanning viruses. The method is characterized by comprising S1, enabling users to transmit file downloading requests to outer networks, enabling firewall equipment to intercept and capture first files fed by the outer networks, forwarding the first files to virus scanning servers, enabling the virus scanning servers to carry out virus scanning on the first files, recording index information of the first files if the viruses are not found in the first files, sampling breakpoints of the first files, storing sampled data in the virus scanning servers, or terminating integral processes if the viruses are found in the first files, and transmitting virus scanning reports to the users; S2, enabling the users to transmit file downloading requests to the outer networks again, enabling the firewall equipment to intercept and capture second files fed by the outer networks, forwarding the second files to the virus scanning servers, enabling the virus scanning servers to compare the second files to the index information and the sampled data of the first files according to breakpoint sampling rules in real time, transmitting the second files to the users if the second files are successfully matched with the index information and the sampled data of the first files, or carrying out virus scanning on the second files if the second files are not successfully matched with the index information and the sampled data of the first files, and forwarding the second files to the users after the second files are completely scanned.

The invention discloses a method for processing optical fiber I/O (input/ output) out-of-order frames based on field programmable gate array, and relates to a storage technology. The method is characterized by comprising the following steps: building an out-of-order information table entry for storing 'breakpoint' information of a current expected data frame when out-of-order frames occur by utilizing local storage resources in FPGA (field programmable gate array) through finding address/ length list in the system cache when the out-of-order frames occur in the FC (fiber channel) data frame receiving process; inquiring whether the expectation offset equals to the offset in the head part of a receiving frame in the out-of-order information list firstly when the out-of-order frames occur once again; inquiring address/ length list again in the cache if the result can not be found out in the out-of-order list, and finding and calculating the address information corresponding to the out-of-order frames, thus the times of searching for the address/ length list in the cache can be reduced, and the efficiency of data exchanging is improved.
