The web point-to-point program transmits data, is the HTTP protocol or TCP/IP protocol TCP/IP protocol and HTTP protocol what is the difference, two Web program point-to-point transmission data, you will choose that one.

To master a protocol, we need to understand it based on it. Here we will analyze the content of the PPP protocol. First, let's take a look at the overview of the PPP protocol. Currently, most analog dial-up connections use PPP as the data link protocol, which has the following features: Error Detection Automatically ne

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

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

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

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

When defining a protocol, it is useful to declare one or more association types as part of the protocol definition. An association type provides a placeholder (or alias) for a type in the protocol, and the actual type it represents is not specified until the protocol is accepted. You can specify the association type by

Layer in Internet protocol stack People have already discussed how to map TCP/IP reference models to OSI models. Because TCP/IP and OSI model groups cannot exactly match, there is no correct answer yet. In addition, the lower layer of the OSI model does not have the ability to truly occupy the real layer; another layer (Network Interconnection layer) is required between the transport layer and the network layer ). Some protocols dedicated to specific
