The paper investigates the problem of Quality of Service differentiation, and an optimal and near-optimal bandwidth allocation in an autonomous subsystem of the TCP/IP network. It defines a control structure making use of existing standard networking technologies. Then a centralized controller - so called Bandwidth Broker is introduced, which allows for fine-tuning of the network parameters under dynamic load conditions.
Two algorithms for the Bandwidth Broker are proposed, one gives exact optimal solution of the bandwidth allocation problem, the second is a heuristic, yet its performance appears to be more than satisfactory.
