Abstract
The theory underlying the modification of the CRC which is used in protocols such as HDLC and ADCCP is sketched, and a possible pitfall in the implementation is described.

When the CRC and TCP checksum disagree
Traces of Internet packets from the past two years show that between 1 packet in 1,100 and 1 packet in 32,000 fails the TCP checksum, even on links where link-level CRCs should catch all but 1 in 4 billion errors. For certain situations, the rate of ...
