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

　　I. Introduction After the program runs, the time protocol (rfc868) is obtained through the network. If it fails to be obtained within five seconds, it will continue to retry after three seconds until it is obtained successfully. After obtaining the time, the program will try to adjust the computer system time. If the adjustment is successful, a message box will pop up: Your computer system time was prooflisted: The time in the information

HTTP protocol and java Protocol After listening to a teacher's course, I felt that I was not familiar enough with HTTP. Therefore, I decided to write this blog post. First, you can refer to this article: http://blog.csdn.net/gueter/article/details/1524447 Part 1: communication process between the browser and the server: Part 2: Introduction to HTTP requests: Part 3: HTTP Response Which book is

Workaround: Add key to Info.plist Let me introduce you to the HTTP and HTTPS protocols in iOS. Recently done a project, began to use the HTTP protocol to achieve client and server-side interaction, and later need to change to HTTPS protocol. Some problems were identified during the modification process, and the solution was as follows: HTTP: NSString *urlstring =[nsstring stringwith

a server error in the "/WCF" application. There is no protocol binding that matches the given address "http://localhost:8001/WCFService.HelloService". Protocol bindings are configured at the site level in IIS or was configurations. This error indicates that the configuration file is not configured correctly.

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
