The linux OSI Layer-7 model, TCP/IP protocol stack, and the structure of each layer reveal big secrets. The osi protocol stack When I learn Linux, I know the OSI model even if I am a little cute. What ?! You don't know !!! Okay, this secret is taken away. Thank you ~~~ I,Two protocols (1OSI protocol model (layer-7) International ProtocolPDU: The data unit transm

The ARP Address Resolution protocol is a TCP/IP protocol that obtains physical addresses based on IP addresses. It works in the second layer of the OSI seven-layer model-the data link layer.Using the ARP Address Resolution protocol, the destination hardware address (MAC address) information can be resolved according to the IP address information in the IP packet

Http protocol and http protocol details HTTP is an object-oriented protocol at the application layer. It is applicable to distributed hypermedia information systems due to its simple and fast method. It proposed in 1990 that, after several years of use and development, it has been continuously improved and expanded. Currently, the sixth version of HTTP/1.0 is use

"Protocol" is an indispensable concept for understanding servers and networks."Agreement (Protocol)" has the meaning of "rules, provisions".In fact, the function of "protocol" is very wide, in the field of communication, "protocol" provides "in the communication, in what circumstances, in what order, what kind of way t

HTTP is a stateless protocol, with two consecutive requests for the same session that are not known to each other, and they are parsed by the newly instantiated environment, which does not save any information about the session, except that the application itself may already be stored in the global object. own understanding, in the ASP: every time the page submission server does not have any relationship, each time the information recorded on the pag

We have analyzed some protocols and the content of the protocol stack. I believe everyone understands the content of the H.323 protocol. Here we will explain the development of this protocol stack. Developing an H.323 protocol stack is an extremely arduous task in the communication design process. The difficulty lies i
