A data processing system for regulating access to a communication network is disclosed herein. The data processing system employs a component that can be implemented in hardware logic or software. The component regulates access to the priority queue or transmit channel that is attached to the shared medium local area network section. All access to the priority queue or transmit channel must pass through this component, thus subjecting all communication transactions to rejection or tracking by the component. The component allocates a frame size based on the information to be transmitted and the priority to assure the transmission will be completed in line with the quality of service required. The component monitors the rate and size of messages to assure that an application's actual throughput does not exceed its negotiated throughput. The component, moreover, is capable of operating in correction mode where throughput and frame size violations are prevented and reported. Alternatively, the component operates in detection mode where violations are recorded and reported to an application.
