The IP protocol is the most important protocol in the family of TCP/IP protocols, which provides unreliable, non-connected datagram transport services. So understanding IP protocols is critical to our learning network.IP headerImportant Field Introduction：4bit First ministerial degree: in 4 bytes, determines the IP head of the largest minister of 15*4=60, the general IP datagram header length of 20, at this

Label:IMAP (Internet Mail access protocol,internet) is formerly known as the Interactive Mail Access Protocol (Interactive mail, Access Protocol). IMAP was an email acquisition protocol developed by Stanford University in 1986. Its main role is that the mail client (for example, Ms Outlook Express) can obtain mail info

Both TCP and UDP are port-based protocols. TCP has links, and UDP has no links. The TCP protocol also drops packets (network problems, the data may be gone)The application is sent to the operating system's cache, and the operating system is removed from the cache, and once the data is lost, it is completely gone. TCP is reliable because the data in its own cache is emptied after it receives a confirmation message.How UDP works I took it out of my own

Commands and responses to the SMTP protocol From the previous communication model, you can see that the SMTP protocol's session between sending SMTP and receiving SMTP is done by sending SMTP commands and receiving an answer to SMTP feedback. After the communication link is established, Send SMTP send mail command message sender, if receive SMTP at this time can receive mail then make OK answer, and then send SMTP continue to Issue RCPT command to con

Transfer http://blog.csdn.net/goodboy1881/article/details/668556 ------------------------------------------------------ Put the three Protocols together for learning because these three protocols are on the same layer. ARP is used to find the MAC address of the Ethernet NIC of the target host, and the IP address carries the message to be sent. The data link layer can get the data transmission information from ARP, and get the data information to be transmitted from the IP address.1. IP

There has been a problem for a long time, everyone is talking about the HTTP protocol, TCP protocol, IP protocol, what is the difference between them, what is the use, no one told me, recently read this "illustrated http" understand some of the film from the bookFirst, understand a transmission stream to expandFor example, HTTP is the first client in the Applicat
