The formula for the optimum packet size required for maximum utilisation of network lines can be derived in several different ways, under a usual assumption of error-free transmission lines/channels. An analysis based on the concept of minimisation of network overheads is used to derive the optimum packet size for lines having random-error characteristics. The messages are assumed to have a Poisson distribution, and the network uses a stop-and-wait strategy for error detection and correction.
