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 (three Phase commitment

Tags: col transmission broadcast tip Local computer network Tran technology familySingle shared broadcast channel, if two or more than two nodes simultaneously transmit, will interfere with each other (interference) conflict (collision): Nodes receive two or more signals at the same time → Receive failed! The MAC protocol uses a distributed algorithm to determine how nodes share channels, that is, when decision nodes can transmit data. It must be base

TelnetWhat is Telnet protocol?Telnet Server Software is our most commonly used Telnet Server software and is a typical client/server model service that uses the Telnet protocol to work. So, what is the Telnet protocol? What features does it have?Telnet is a protocol located at layer 7th of the OSI model---application l

I. Overview A protocol is a delegate (delegate)/proxy, which is an object that provides an opportunity to respond to changes in another object or to affect the behavior of another object. A protocol can only be used for one purpose, that is, to declare a heap of methods for an inherited class. The base class adheres to the Protocol, and its deriv

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 protocol The IP protocol is the core of

TLS encrypts the network connection with SSL at the transport layer. Most of the Internet login is the use

Brief introductionHypertext Transfer Protocol (hypertext Transfer Protocol, referred to as HTTP) is the application layer protocol. HTTP is a request/response protocol that sends a request to the server after a client has established a connection with the server, and responds to the request after the server has receive

1. Protocol Buffers Introduction　Protocol Buffers (PROTOCOLBUFFER/PROTOBUF) is a data-description language developed by Google, similar to the ability of XML to serialize structured data that can be used to persist data or serialize data to be transmitted over a network. Mainly used in data storage, communication protocols and so on. This stage supports 6 programming languages such as C + +, JAVA, Python, O

HTTP protocol Summary HTTP protocol (Hyper-Text Transfer Protocol) HTTP is a stateless, application-level protocol based on the request-response model, which is based on a TCP link (three handshake) and an ongoing link mechanism in the HTTP 1.1 version, most of which are built on the HTTP

HTTP is a stateless protocol, with two consecutive requests for the same session that are not known to each other, and they are parsed by the newly instantiated environment, which does not save any information about the session, except that the application itself may already be stored in the global object. Own understanding, In asp: Every time the page is committed, the next commit will not be remembered, except that the application itself may have be

Application layer protocol: Each application tier is designed to solve a class of application problems. The solution of the problem must be accomplished through communication and collaboration between multiple application processes located in different hosts. Strict rules must be observed between application processes. Application-layer protocols should be defined as follows: the types of messages exchanged between application processes, such as the i
