In a packet switched network, several types of transmission may connect a pair of nodes of the network. The delay characteristics of each type of transmission may be significantly different and so a single queue to the node pair operating under a first-come, first-served rule may not be best. This paper develops both exact and approximate mathematical models that determine various system-level performance measures for a K,N scheme. Under this scheme arriving packets are placed in the queue for one type of transmission until the size reaches K, whereupon arriving packets are diverted to the other transmission system. When the number of packets at the first system drops to NK, arriving packets are placed in the first queue.
