Note: This note is written from a programmatic point of view, which is what I think is helpful for programming, not from the perspective of a network expertise. The following illustration shows the different partitioning of the architecture of the computer: the OSI seven-layer protocol architecture, the architecture of TCP/IP, and the architecture of the five-tier protocol: The following figure illustrates the changes that the application process's

I. fault descriptionFault Location:An electronics Bureau Fault symptom:The network is severely congested, and communication between internal hosts or even between internal hosts is interrupted. Fault details:Network Communication is suddenly interrupted, some VLANs cannot access the Internet, and access to other VLANs is also interrupted. Ping packet testing is performed in the IDC, it is found that the ping packet from the central switch to the host

Note: This note is written from the programming perspective, that is, the content is something I think is helpful for programming, rather than from the perspective of a network professional knowledge. The Comparison of Different Computer Architectures: OSI Layer-7 protocol architecture, TCP/IP architecture, and five-layer protocol architecture: It indicates the changes in the data transmitted by the application process at each layer. It indicates the

specific structure is as follows: Setsockopt (level, optname, value) Level defines which option will be used. It is usually SOL_SOCKET, which indicates the socket option in use. It can also set protocol options by setting a special protocol number. However, for a given operating system, most protocol options are clear, so for simplicity, they are rarely used for apps designed for mobile devices. The optname parameter provides special options. The setting of available options varies slightly dep
