transports files over tcp ip network

defects inherent in the current network protocol TCP/IP. The information security on the network can be divided into three parts: System Information Security, communication information security and information content security. The security of System information on network

Communication between the two network programs requires a link channel between them, which consists of a five-tupleFive tuples:(protocol, local IP address, local port number, remote IP address, remote port number)Socket programming principle Socket Socket InterfaceCommunication between network programs relies on the so

Http://blog.chinaunix.net/uid-20357359-id-1963666.html Recently, I tested programs on the new platform. Some issues that have not been noticed before have become performance bottlenecks. Some problems can be solved by setting some TCP/IP options, of course, the fundamental solution is to refactor the code and redesign the Server framework. First, list several TCP

Php uses http or tcpip to upload large files. it is better to use http to upload files of 2 MB by default in php, if you upload large files such as videos using the same http protocol as uploading small files, or developing an upload client in other languages based on the TCP
