Abstract
A method and apparatus for determining when all packets of a message sent over a computer network by a source computer have arrived at a destination computer includes a counter located at the source computer for storing an initial value and for assigning a delta value to each packet in the message, where the last packet stores a delta value that is equal to the counters initial value minus number of packets previously sent modulo the counter range; and includes an accumulator located at the destination computer for extracting the delta value from each packet of the message. The destination computer is notified that all packets in the message have arrived only when the sum of the extracted delta values stored in the accumulator is equal to zero modulo the capacity of the accumulator.
