Learn the special status of TCP in the TCP Series The previous two articles introduced the TCP status change and demonstrated the normal status change between the client and the server through experiments. Next, let's take a look at several special states in the Process of TCP status change. SYN_RCVD When a

1.TCP of servicesin a TCP connection, only two parties communicate with each other. TCP provides reliability in the following ways:1) The application data is segmented into the data block that TCP considers most suitable for sending. This is completely different from UDP, where the application-generated datagram lengt

When learning the network basics, the transport layer protocols include TCP and UDP; In Linux network programming, we use the socket API to implement network communication. So: How does the status of Socket API correspond to that of TCP? We can see through: How to complete three handshakes and four waves in Socket System calls: Sock_dgram, that is, the connect operation knowledge in UDP registers the IP a

Currently, many TCP-based network protocols are available, including telnet, ssh, ftp, and http. These protocols can be roughly divided into two categories based on data throughput: (1) interactive data types, such as telnet and ssh. In most cases, these protocols only exchange small traffic data, for example, press the keyboard to display some text. (2) Data is block type, such as ftp. This type of Protocol requires that

1. The need for TCP keepalive1) Many firewalls are automatically closed for idle sockets2) for non-normal disconnection, the server is not able to detect. In order to reclaim resources, a detection mechanism must be provided.2. Factors that cause TCP disconnectionIf the network is working properly, the socket is gracefully closed with close operation, so everything is perfect. However, there are many situa

TCP provides a connection-oriented, reliable byte-stream service.Connection-oriented means that the sending and receiving parties must establish a TCP connection before exchanging data. By the way, a TCP connection has only two sides, so broadcast and multicast cannot be applied to TCP.The byte stream refers to two applications that exchange a byte stream of 8bit

message is passed to the client, because the client is already in the Syn_send State, As a result, the client enters the established state, and the server instead discards the duplicate SYN packet sent via the Connect function, as shown in the third diagram. And after the connection is established, the sending packet due to SEQ is discarded by the SYN packet sequence number, and the server receives the serial number is the delay of the old connection SYN message sequence number, causing the ser
