摘要： A network intrusion protection system (NIPS) is built at an important network node, for example, at a boundary router, for filtering network packets containing malicious intrusion/attacking behaviors. A network card of the NIPS includes a microprocessor, a network packet decode procedure and a malicious intrusion packet filtering procedure, for filtering malicious network packets in advance according to header information of the network packets. Then, a central processor of the NIPS is used to parse the contents in the rest network packets, and determine whether the network packets are malicious packets according to an intrusion behavior definition file. The network packets are discarded if the network packets are malicious. Otherwise, the network packets are transferred to computers in internal local area network if the network packets not malicious.

摘要： A system testing method through a subsystem performance-based generator is used to perform tests on a single module performance in a Linux system. The subsystem performance-based generator generates an initial performance testing parameter, and sets a memory occupying space, CPU occupation rate, and I/O performance of a module to be tested according to the testing parameter. After setting the testing parameter, the performance of the whole Linux system is tested through a performance testing tool. Next, another performance testing parameter is generated by the subsystem performance-based generator, and then the system performance test is performed after setting the module to be tested accordingly. Various performance value settings of the module to be tested are dynamically adjusted through the method, and then the performance test of the whole system is performed, so as to accurately find out the bottleneck problem of the performance, thereby improving reliability of the system test.

摘要： A data structure for an image file includes an image file head, a data area, an index table, and file tail information. The image file head records hardware parameter information of a storage device and partitions the storage device into a plurality of data units. The data units are compressed to generate corresponding compressed data blocks. The generated compressed data blocks are stored in the data area. The index table uses an index value to record start positions of the data units and positions of the compressed data blocks in the image file into the index table. The file tail information marks a file length of the image file. During network transmission of the image file, a destination may restore the received compressed data blocks to the corresponding positions.
