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

Real-time Transport Protocol Introduction: RTP protocol Introduction, RTCP protocol Introduction, RTSP protocol Introduction (ZZ)

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

Real-time transmission protocol Introduction: RTP protocol introduction, RTCP protocol introduction, RTSP Protocol Introduction

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

Introduction of Socket/UDP protocol based on UDP Protocol/UDP protocol lookup dns/process Introduction/operating system and process history

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

Network protocol Basic Knowledge SMTP protocol and UDP protocol

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

2.TCP/IP Protocol Analysis-IP Protocol, ARP protocol, and RARP protocol

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

Lora Protocol Encryption

4.3.3 If a data frame contains a data payload, the frmpayload must be encrypted before the mic is calculated.The encryption mechanism is based on the algorithm referred to by IEEE 802.15.4/2006 Annex b[ieee802154], using an AES key of length 128bits.By default, the LoRaWAN layer is the data encryption/decryption for all fport. If the application layer is convenient, you can also decrypt the data in addition to FPort 0 in the upper level of the

TCP/IP Study Notes (3)-IP protocol, ARP protocol, RARP Protocol

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

TCP/IP Detailed learning notes (3)-IP Protocol, ARP protocol, RARP protocol

Put these three protocols together because the three protocols are on the same level, the ARP protocol is used to locate the target host's Ethernet NIC MAC address, and the IP hosts the message to be sent. The data link layer can get the data transfer information from ARP, and the data to be transmitted from IP.1.IP protocolThe IP protocol is the core of the IP protocol

Video Transmission protocol Summary, bit rate __ Video protocol

Video image transmission has the following characteristics: 1 requirements for small transmission delay, high real-time, 2 transmission flow, requiring high transmission efficiency; 3 allow transmission errors or data loss on certain programs. According to the above characteristics, it is more ideal to use UDP protocol to transmit video relative to TCP protocol. UDP is the abbreviation of User Datagram
