AJP13 is the directional package protocol. For performance reasons, the binary format is used to transmit readability text. The Web server is connected through a TCP connection and a servlet container. To reduce the cost of process generation sockets, the Web server and the servlet container try to maintain a persistent TCP connection and reuse a connection for multiple request/reply loops. Once a connection is assigned to a specific request, it is no
UDP belongs to the transport layer together with the TCP mentioned earlier. UDP differs from TCP in that it is a non-connection-oriented protocol, that is, when both parties communicate with each other, they do not need to establish a connection beforehand. So the UDP header saves a lot of fields, and the UDP header is only 8 bytes. The UDP header consists of the following: The UDP header contains only the source port and destination port, plus th

The routing information protocol (RIP) is one of the earliest and most basic protocols in the routing protocol. Although its current use is gradually unable to meet our network construction needs, we still need to fully master this protocol as a learning basis.

Preface: Because OBJECT-C does not support multiple inheritance, it is often replaced with protocol (protocol). The Protocol (protocol) can only define a common set of interfaces, but cannot provide a specific implementation method. That is, it only tells you what to do, but specifically how to do it, it does not care.
