Abstract

Disclosed is an algorithm to significantly improve the IND$FILE error detection procedure while maintaining backward compatibility with the previous algorithm. The existing IND$FILE file transfer protocol can suffer from reliability problems, since its error detection scheme is based on a vertical checksum technique. The protocol has been redesigned such that it maintains backward compatibility with the existing algorithms and programs, and provides the option of using a Cyclic Redundancy Checking (CRC)-based algorithm for much-improved reliability in error detection and correction.
