excerpt from Baidu Encyclopedia: three-time handshakeLockThis entry is compiled and applied to the scientific entry of "Science China" encyclopedia. three handshake (three times handshake;three-way handshake) The so-called "three-time handshake" is how the amount of data sent each time is tracked to synchronize the

TCP (transmission Control Protocol Transmission Control Protocol ( TCP /wireless) is a connection-oriented, reliable, byte-stream-based transport-layer Communication agreement defined by the IETF RFC 793. In the simplified computer network OSI model, it accomplishes the function specified by layer Fourth transport layer, and the User Datagram Protocol (UDP) is Another important transport protocol in the same layer. In the Internet Protocol family (Internet Protocol suite), the TCP layer is the

OSI Computer Network 7-layer modelTCP/IP layer four network modelThe transport layer provides logical communication between applications (end-to-end), the network layer provides host-to-host communication, and the transport layer provides reliable services.The usual handshake in TCP refers to the definition of a connection and the process of establishing a connection. The IP protocol is not connected, but TCP is linked.Port : The data link layer relie

A few days ago, the lab group threw out a question:can the three handshake process built by a TCP connection carry data? suddenly found that they really do not know this problem, on weekdays with tcpdump or Wireshark grab bag, never notice the third handshake ACK Packet has no data. So hurriedly with NC with Tcpdump grabbed a few packs want to test. But after many experiments, it was true that the third

= Initiator req+1, paired at both ends. Tertiary handshake The so-called three-time handshake (three-way handshake) establishes a TCP connection, This means that when a TCP connection is established, a total of 3 packets are sent to the client and the server to confirm the connection establishment. In socket programming, this process is triggered by the client

The three-time handshake of the TCP_IP in the socket and four waves: (i) The three-time handshake of TCP in the socket establishes the connection: (1) TCP establishes a connection to perform a "three-time handshake", that is, to exchange three groupings. The approximate process is as follows: The client sends a SYN J to the server The server responds

After receiving the PSH, TCP submits the cache to the application process, regardless of any subsequent messages.Two, 3 handshake1.3-Time handshake processTCP is the Transport layer protocol in the Internet, using three-time handshake protocols to establish a connection.

What is stdafx. h and stdafx. cpp used? Why must each of my CPP files contain stdafx. h? Windows and MFC include files are very large, even if there is a quick process Program It takes quite a long time to compile the program. Since each. cpp file contains the same include file, it is silly to process these files repeatedly for each.

Environment variables need to be added Add method: Right-click my computer> Properties> advanced> environment variable User variables. The environment variables to be added include:1. Path: C:/dev-CPP/bin. If this variable already exists on the computer, add "; C:/dev-CPP/bin" to the original variable, the path must be separated by semicolons.2. LIBRARY_PATH: C:/dev-

. H and. cpp files, First, all the code can be placed in a cpp file. This is no different for computers, However, for a project, bloated code is a disaster and is not suitable for reading and post-maintenance, Therefore, the. h and. cpp files regulate programmer writing habits. Usage 1. The. h file is directly # include to the required.

TCP three times handshake When TCP establishes a connection, there will be three handshake processes, as shown in the following illustration, Wireshark intercepts three handshake three packets. The fourth package is HTTP, which means that HTTP does u
