Insect pests and diseases are major constraints to crop yield. Solutions to pests and diseases management are inevitably not independent of location. In the current study, a web-base geographic information system for crop pests and diseases management system was developed using ArcIMS, ASP.NET, networking and database management technologies. The application system provides client users with pests...
We propose to use the SYN/ACK-CliACK pair's behavior to detect the various SYN flood attacks more accurately. The SYN/ACK packets carry the full information of the TCP connections and it is impossible for the attacker to evade the detection by spoofing the control packets. Moreover, we use a space efficient data structure, counting Bloom filter, to recognize the CliACK packet and the memory cost is...
A multi-server video monitor system based on streaming media communication technology is proposed. Large-scale, long-distance monitoring requirements have been met. The video monitor software is researched, which has the function of video restoration, proprietary protocol is used to realize video transmitting smoothly. In the part of the software programming, multi-threaded mechanism and double buffering...
