Abstract:

Messages arriving at a store-and-forward switch are stored in a drum. Each message stored takes up a number of blocks of drum storage that depends on the message length in characters. It is assumed in the report that the arriving messages are drawn at random from a message population thus the number, say N, of messages that fill the drum is a random variable. It is shown, by means of renewal theory, that the distribution of N is approximately a normal distribution whose mean and variance are simple functions of the drum size and the parameters of the message population. Illustrative examples are given.
