encapsulation, the socket itself is not a protocol, but a call interface (API), through the socket, we can use the TCP/IP protocol. In fact, the socket is not necessarily associated with the TCP/IP protocol. The socket programming interface is designed to adapt to other network protocols as well. So, the advent of soc

Various protocols have been involved since connect. At present, the TCP/IP protocol is clarified first. First, the structure of TCP (transmit Control Protocol) is matched with the struct: # Define header_size 64/* maximum header size */ Struct tcphdr {/* TCP Header */ /* Sending terminal slogan: 16 bits Identifies t

The detection of SYN attacks is very convenient, when you see a large number of semi-connected sta

application is sent to a physical network, it is transmitted from top to bottom along the protocol stack. The data encapsulated by TCP is called a TCP packet segment. There are also UDP datagram and IP datagram. The data encapsulated by the data link layer is called a frame ). An Ethernet frame uses a 6-byte physica

protocol. There are many application layer protocols, such as HTTP, FTP, and telnet. You can also define the application layer protocol by yourself. The Web uses HTTP as the application layer protocol to encapsulate HTTP text information, and then uses TCP/IP as the transport layer protocol to send it to the network ."

a special need for services, it needs to publish and run the service for the server, and for the client, it needs to invoke the service, and for the developer it is necessary to write code that defines, publishes, runs, and invokes the service. Services can only be run on a specific host, such as console application processes, Windows or Web application processes, or Windows service processes, or the most common IIS hosts. Inside the host, the channel stack
