That is, it starts from the cable test and ends with packet capture and decoding.◎ Integrate almost all network testing tools The network integrated protocol

Over the past decade, many new software technologies and platforms have emerged. Each new technology requires specialized knowledge to create applications with good performance. Program . As various Internet technologies (such as blogs) make it easy for disappointed users to deny your applications, you do need to put performance first. Early in the plan, you should add response performance requirements and create prototypes to determine possible technical limits. Throughout the development proc

When processing TCP data, we need to consider a problem of sticking packets. The so-called sticking packet is that the data received this time is not necessarily completely corresponding to the data sent by the other party. the data sent by the other Party may need to be received multiple times before it can be completed. The actual situation should be reviewed. To solve the packet ordering problem, a data
