Abstract
A method and apparatus for inserting sequence number and timestamp information into a network data packet in a manner which is checksum neutral with respect to a checksum precalculated in the network protocol portion of the data packet. The checksum neutral addition of sequence number and timestamp is accomplished by in addition to adding to the payload portion a sequence number and timestamp, also adding a value which is a modified version of the sequence number and of the time stamp such as an inverse value.
