Cyclic Redundancy check Cyclic Redundancy test is a set of verification codes based on data computing. It is used to check whether the data is changed or transmitted incorrectly during transmission.Algorithm principle Assume that 15-bit binary information G = 101001110100001 needs to be sent during data transmission. The binary code can be expressed as an algebraic polynomial g (x) = x ^ 14 + x ^ 12 + x ^ 9

Background:With the information office becoming more and more popular, people's office relies on the Internet more and more, it, the network in the enterprise's influence is more and more big. Therefore, the reliability of the enterprise network becomes very important. For an internet company or a company that needs to use a network to work properly, a broken network means that employees cannot work properly and the company has a lot of money to lose. In such a context, large companies and the f

Meaning and purpose of data redundancyAfter digitizing video and audio signals, the volume of data is staggering, so storing large amounts of image and audio information needs to greatly improve the storage capacity of the system, usually by using a large disk or disc, but this is just one way to solve mass storage, and the role of data redundancy is to save additional data or data on a separate hard disk, to prevent data loss, the following explanati

Abstract:For the PC104 SCM/deth dual-port ethernet card, an intelligent dual-redundancy Network Driver Based on the Vxworks system is designed, the driver provides functions such as network communication fault diagnosis and intelligent switching between NICs. By testing the performance of the smart dual-redundancy driver, the correctness and effectiveness of the design are verified.Keywords:VxWorks operatin

Introduction With the gradual improvement of Ethernet stability, anti-interference and bandwidth problems, Ethernet is entering the industrial control field on a large scale. It is used in industrial process control, communication, spacecraft and navigation systems, and has extremely high requirements on the high speed of reliability and fault response. Currently, redundancy design has been widely used as an effective method to improve the reliabili

HypothesisThere is a "Reader table", and the table has a "borrow Certificate Status" field. This field should be set to "normal", "Report loss", or "cancel account", as shown in the following table: Reader table (table 1 ): Readerid Readerstatus 1 normal 2 normal 3 report loss 4 normal 5 Cancel account The problem is that there will be data
