(With the multi-level and diverse development of the Internet, Internet cafes have expanded from the simple use of instant messaging, reading pages, and e-mails to running many online games, online video and audio, interactive education, P/2P and other technologies. use. Usage properties also exhibit variety and complexity, and as a result, these usages are more stringent and demanding on our web service quality requirements. At present, the network equipment of most Internet cafes does not have the extended functions such as intelligence and interactivity of high-end network equipment. The heart is there but the power is lacking. After all, relying on the experience of network administrators and some simple and traditional troubleshooting methods: there are big errors in both time and accuracy, which also affect work efficiency and normal business operations. SnifferPro is a well-known network protocol analysis software. This article uses its powerful traffic graphic system H/OSTTable to monitor network traffic in real time. In terms of monitoring software, we chose the more commonly used snifferpro of NAI companies. In fact, many Internet cafe administrators have relevant experience in monitoring the network: when there is a problem with the network, or when detecting network conditions, use P/2P terminators, network Law enforcement and other network monitoring software. Such software has a great advantage: it can perform traffic query without configuring port mirroring (original snifferpro can also work in such an environment). This seemingly convenient method still has many disadvantages: because its working principle uses the ARP address table to deceive the address table, it may lead to a lot of extraneous problems, such as dropped calls, slow network, huge ARP broadcast. increase. This is incredible for requesting a normal network.)
