Abstract
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.
Claims13
A method for reserving network resources for a transmission from a first network user, the method comprising:
- receiving a resource reservation request from the first network user to initiate a reservation;
- confirming that the required resource is available;
- sending from the network to the first network user a ticket message containing reserved network resource allocation information, the reserved network resource allocation information being associated with network resources allocated for use by the first network user,
- allowing access to the network for a transmission from the first network user, only if the transmission includes the ticket message containing the reserved network resource allocation information.
A node for a communications network, comprising:
- means for receiving an access request from a user;
- means for determining whether resources are available for a received access request;
- means for transmitting to the user a ticket message containing reserved network resource allocation information, if resources are available;
- and
- means for restricting access to the network to allow access for transmissions only if the transmissions include an appropriate ticket message containing the reserved network resource allocation information.
A method of achieving admission control in a network, the method comprising:
- receiving a resource reservation request from a user to initiate a reservation;
- sending to the user a ticket message containing reserved network resource allocation information;
- requiring a subsequent transmission from the user to return the ticket message;
- and
- applying admission control on the basis of the content of the ticket message.
