Studies link capacity allocation for a finite buffer system totransmit multimedia traffic. The queueing process is simulated with realvideo traffic. Two key concepts are explored. First, input traffic inthe low frequency band stays intact as it travels through afinite-buffer zero-loss system. Second, the link capacity requirement ateach node is essentially captured by its low frequency input traffic(filtered at a properly selected cut-off frequency). Hence, one mayoverlook the queueing process at each node for network-wide traffic flowin the low frequency band. The authors propose a simple, effectivemethod for link capacity allocation and network control using on-lineobservation of traffic flow in the low frequency band. The experimentalstudy points out a possible new direction for control of high speednetworks
