论网络中的一种差错检测技术——CRC

CRC: An Error-detection Code in Computer Network

CRC是目前网络中普遍采用的一种检测码 ,只有真正了解和掌握它 ,才能选择合适的CRC ,使传输帧达到冗余位少、漏检率低的目的 ,从而提高传输效率。本文从CRC的理论基础、冗余位的产生方法。

CRC is an error-detection code widely used in the computer network. When comprehending the principium of it, we can choose appropriate CRC so that redundancies and transmission errors can be reduced in data transmission. This article illustrates its theoretical foundation, production of redundant codes, performance analysis as well as means of implementation.
