Strategy for Designing Error Detection Schemes for General Data Networks.

摘要

Any real-world network system is subject to a variety of errors. Error detection mechanisms such as CRCs and length fields must be included along with the data to prevent errored data from being accepted as error-free by the destination. This paper identifies the fundamental issues involved with providing error protection and specifies guidelines for designing protocols that effectively and efficiently handle errors. A five step methodology is presented that provides insight into first, the order in which errors should be considered when designing an error detection scheme, second, which types of error detection mechanisms are most effective, and third, which layer should be responsible for detecting a given type of error.
