layer (DL,Link layer) and the application layer (AL, application layer, respectively, implement the ETHERCAT protocol toand application-level communication protocols.Data link layer is the data exchange layer of ESC and slave microprocessor, ESC and slave microprocessorcan be either SPI (Serial peripheral Interface, serial Peripheral Interface) or MCI (MicroController Interface, microcontroller interface)

of the data link layer of the ethercat network. It has four network interfaces to connect to the ethercat network, and provides rich interfaces and application controllers for data exchange. For example, the slave application controller uses the ipv335 DSP chip, which is TI's latest 32-bit floating point DSP chip for industrial control. In software, the ethercat

2. Telnet protocolThe Telnet protocol is a member of the TCP/IP protocol family and is the standard protocol and main way of Internet remote Login service. It provides users with the ability to perform remote host work on the local computer. Use a Telnet program (such as Putty) on the end user's computer to connect to the server. End users can enter commands in t

http://blog.csdn.net/heanyu/article/details/6202500 RTP (Real time Transport Protocol) RTP is a transport protocol for multimedia traffic on the Internet that is published by the IETF (Internet Engineering Task Force) as RFC1889 . RTP is defined as a one-to-many transmission, with the purpose of providing time information and implementing stream synchronization. Typical applications for RTP are built on U

RTP (Real Time Transport Protocol) RTP is a transmission protocol for multimedia data streams over the Internet.Rfc1889Release. RTP is defined to work during one-to-one or one-to-many transmission. It aims to provide time information and implement stream synchronization. Typical RTP applications are built on UDP, but can also work on TCP, ATM, and other protocols. RTP itself only guarantees the transmissio

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
