Adaptive channel capacity, distributed message-switching communication networks
Abstract
Adaptive branch channel capacity models under variable traffic load are studied. It is assumed that channel capacities of all branches of a distributed message-switching communication network are adjustable over intervals comparable to a few interarrival and or interdeparture times. The adjustment is accomplished by observing the number of messages in finite storage buffers. A combination of time delay of a branch and the utilization cost of channels is considered as the objective function to be minimized. Three different models for branch capacity assignment were studied for control of a single buffer. Dynamic Programming was used to find the best channel capacity control policy for a single buffer. An expression identifying the output rate of a buffer, called affective departure rate, is defined.
