ABSTRACT:
A method for determining optimum segment size in a data transmission system which uses a communications network that imposes a Maximum Transferable Unit (MTU) data packet size. The total cost (host processing plus transmission) is determined for a segment equal in size to the MTU. This cost is sequentially compared to the total cost of segments which are integer incremented multiples of the MTU. When the comparison indicates that the segment which is an integer multiple of the MTU exceeds the total cost of transferring the segment equal in size to the MTU, the comparison is terminated and the segment size is set equal to the segment size of the next prior comparison.
