目前,计算机网络通信系统大部分采用差错检测控制方法,检测通信线路传输信息并进行纠正,提高通信线路传输质量。CRC(Cyclic Redundancy Check)算法就是一种差错检验控制方法,在计算机网络通信中,选择合适的CRC,冗余位少、漏检率低、传输效率高,能够比较准确的校验数据通信线路传输的信息。本文介绍了CRC算法的原理、分析、设计等,探讨了计算机网络通讯中CRC算法的应用研究。
At present, most of the computer network communication systems adopt the error detection and control method, and detect the transmission information of the communication line and correct it, so as to improve the transmission quality of the communication line. CRC (Cyclic Redundancy Check) algorithm is a kind of error-checking control method. Computer network communication, select the appropriate CRC, fewer redundant bits, low detection rate, high transmission efficiency, can more accurately verify the data communication line transmission Information. This paper introduces the principle, analysis and design of CRC algorithm, and discusses the application of CRC algorithm in computer network communication.
