Pre-verification of checksums used with checksum-based header compression

摘要

A method or apparatus for preverifying checksums ensures the checksums are reliable for header decompression (300) purposes. The checksums are pre-verified (304) on the compressor (50) side before being transmitted (308) to the decompressor (60). Verification (304) of the checksums includes testing against a number of packet loss scenarios to ensure reliable detection of errors. In addition, pre-verification (304) helps increase and/or maintain compression efficiency by keeping the length of checksums from becoming unnecessarily long.
