A method is provided for achieving admission control to a public connectionless packet network. This provides a method of access control which allows service differentiation in a form which permits a user to receive a quality of service guarantee which is better than a "best effort" service. Each transmission by a user across the network includes a message sent to the user from the network. The message includes information about the priority level of the transmission, based on the user's contract with the network provider, and can subsequently be extracted by the network to determine how to handle the transmission, and to determine the resources available for future transmission requests.
