Data communication networks transmit much information besides the actual users messages. This extra information is called protocol information. This thesis extends Gallagers initial work in providing a information-theoretic lower bound to how much of this protocol information is absolutely necessary for the proper operation of a network. The lower bound is a function of the average amount of time messages are allowed to be delayed before being transmitted. The bound suggests that the strategies considered by Gallager are close to optimal.
