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

Recently, I am crazy about supplementing the foundation and looking at the TCP/IP protocol. However, the content in the book is too abstract, and there is no data instance. After reading it for a long time, I forget it. Therefore, we moved a sniffer and captured the data packets. Haha, I had to explain it in the book, and I understood it faster. I will add some basic knowledge. Let's get started with the IP

One; prefaceThe people who have learned the TCP/IP protocol have a feeling, this thing is too abstract, there is no data instance, after reading soon forget. This article will introduce an intuitive learning method, using the Protocol analysis tool to learn TCP/IP, in the process of learning to visually see the specific transmission process of data.For beginners to understand more easily, this article will

Preliminary Study on WCF-19: WCF Message Protocol, Preliminary Study on wcf-19 ProtocolWCFMessage Protocol Overview When a WCF application is generated, developers usually pay close attention to the data structure and serialization issues, rather than the message structure carrying data. For these applications, it is easy to create data protocols for parameters or return values. However, it is equally im

HTTP protocol learning and http protocol Learning 1. HTTP Overview HTTP is actually a set of language communication rules! Http uses a reliable data transmission protocol. Therefore, even if the data comes from the other end of the earth, it can ensure that the data is not damaged or messy during transmission. B/SStructure In the browser, the user requests the sp

Differences between the TCP protocol and the UDP protocolWhether connection-oriented connection oriented non-connectedReliable unreliable transmission reliabilityApplications transmit small amounts of data in large amounts of dataSlow speedTCP requirements and server remain connected UDP does not require TCP data to be ordered (first written data is sprints first received) UDP data is unorderedAsyncsocket is a set of open source libraries designed for

The MMS protocol is used to access unicast content on Windows Media publishing points. MMS is the default method for connecting to the Windows Media Unicast service. If the audien

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
