TPC/IP Protocol is a Transport layer protocol, which mainly solves how data is transmitted in the network, and HTTP is the application layer protocol, which mainly solves how to wrap the data. regarding the relationship between TCP/IP and HTTP protocol, the network has a relatively easy to understand: "When we transmit

One, the distinction between communication and communication protocol:1, the traditional meaning of "communication" mainly refers to telephone, telegraph, telex. The "message" of the communication means the messages, and the media messages are passed from one end to the other through the communication network. The content of media message is mainly voice, text, picture and video image. The composition of its network is mainly composed of electronic eq

type field in struct packet_type. Each element in the table points to a chain table of struct packet_type. A chain table ptype_all of struct packet_type is also defined. The protocol processing program on this linked list receives packets of the Protocol. It is mainly used for network tools and network sniffer to receive packets. For example, the tcpdump packag

PPP is one of the most basic protocols in the network. PPP is the main content of this article. First, let's take a look at the basic concepts of the PPP protocol. The Point-to-Point Protocol is a data link layer Protocol designed to transmit data packets between equal units. This link provides full duplex operations and transmits data packets in sequence. PPP pr

SIP (Session Initiation Protocol) Conversation Initiation Protocol is an application layer control (signaling) protocol for network telephony and conferencing. It is mainly a multimedia communication protocol based on IP network. It can realize the signaling functions are also using RTP as a media transmission

This paper mainly introduces the implementation of the 802.1Q VLAN protocol in the Ethernet switch, and some basic contents of the 802.1P protocol, details of the implementation of the two Protocols, and reference data of the 802.1Q and 802.1P protocols. First, 802.1Q protocol 802.1Q protocol, that is, Virtual bridge

A host that communicates in the same network (which is not specifically referred to as an Ethernet network) must have the MAC address of the target host to correctly send the data to the target host, so how to know the MAC address of the target host. Can be passed through the ARP protocol. The ARP protocol is used to obtain the corresponding MAC address of the destination IP address, that is, the ARP

Baidu Encyclopedia Description:Hypertext Transfer Protocol (Http,hypertext Transfer Protocol) is one of the most widely used network protocols on the Internet. All WWW documents must comply with this standard. HTTP was originally designed to provide a way to publish and receive HTML pages. 1960 American Ted Nelson conceived a way to process text messages through a computer called hypertext (hypertext), whic

Today, a customer response, Remote Desktop can not connect, I looked, ping is normal, telnet a remote port, but also can connect, but the remote Desktop is always not connected, first to help him restart a bit. After the reboot, the remote can log in, went to check the server logs, and found such an error: The RDP protocol component x.224 found an error in the protocol stream and interrupted the client c

The concept, model, and Protocol family of TCP/IP Control Protocol/Internet Protocol are abbreviated as Transmission Control Protocol/Internet Protocol, also known as network communication Protocol, it is the most basic

Internet Protocol Summary, Internet Protocol Today, I saw an article on network protocol on my way to work. I think it's a good job to write. Well, of course I want to keep some good stuff. I 'd like to share it with you here! This article is reproduced in the network log of Ruan Yifeng Author: Ruan Yifeng Original article: http://www.ruanyifeng.com/blog/2012/05/

different physical machines are consistent. In order to solve this distributed consistency problem, predecessors summed up many typical protocols and algorithms during the repeated trade-offs between performance and data consistency. Among the more notable are the second-order commit protocol (two Phase commitment Protocol), the Sankai commit protocol (both Phas

Analysis of TCP/IP layer-4 protocol system and tcpip layer-4 Protocol TCP/IP layer-4 protocol system 1) The link layer, also known as the data link layer or network interface layer, usually includes the device driver in the operating system and the network interface card corresponding to the computer. They work together with the physical interface details of the

HTTP protocol, Hyper-text Transfer Protocola. The HTTP protocol is now using version 1.1.B.The HTTP protocol is the application-layer protocol, which requires the transmission of data using a reliable transport protocol. Typically the Transport layer

MySQL5.6 has many new features, many of whom are interested in the global transaction ordinal function (Gtids). The reason why everyone is interested in this feature is that it's always a hassle to reconnect from the server and a new primary server, but it's easy to do after enabling the Gtids feature. However, the use of Gtids not only replaces the old binary log file/location with a separate identifier, it also uses a new replication protocol. If yo

Protocol buffers is a data description language developed by Google, similar to XML that can serialize structured data for data storage and communication protocols. At this stage of support Hold three programming languages, such as C + +, JAVA, Python. It is a binary format, much faster than using XML for data exchange. It can be used in data communication between distributed applications or in heterogeneous environments. Http://code.google.com/intl/z
