According to the previous several protocols, the IP protocol, TCP protocol, and UDP protocol are combined, so the TCP/IP protocol is available. Nowadays, communication between many applications is based on the TCP/IP protocol and
: the client retains a long-lasting http connection, waiting for the message to be received as soon as the server has a new message. Because polling often results in no new messages on the server side, this push notification pattern is more efficient than polling.5. Another chestnut, Client 1 and Server-side dialog using the XMPP protocol:Client 1 connects to an XMPP server, sends a message (subject and con

To write a network program, you must use socket. This is what programmers know. In addition, during the interview, we will also ask if the other party will be able to program the socket? In general, many people will say that socket programming is basically listen, accept, send, write and other basic operations. Yes, just like common file operations, as long as they have been written. For network programming, we must also call it TCP/

At the same time, the confirmation number is set to customer's ISN plus 1 to confirm the customer's SYN message segment. A SYN will occupy an ordinal C. The customer must set the confirmation serial number to the server's ISN plus 1 to confirm the SYN message segment of the server (message Segment 3) The three segme

The form field is used to control the data volume sent by the recipient, in bytes. The end of the TCP connection determines its receiving form based on the size of the cache spa

Therefore, the packet is cached in a buffer until an ACK is confirmed.In the TCP/IP protocol, the TCP protocol provides a reliable connection-oriented service, a three-time handshake (establishing a connection) and four waves (closing

On the Network layer (IP protocol), increase the MAC address as the purpose of the communication and then forward to the link layer. In this way, the communication request to the network is ready to complete. The server at the receiving end receives data at the link layer, which is sent sequentially to the upper layer, until the application tier. When tra
