Multidomain access control of data flows associated with quality of service criteria

摘要

The invention concerns an access controller (AC₁, AC₂) to a domain (N₁, N₂) of a data network, including a set of routers (R₁, R₂, , R₅) characterized in that it includes: a receiver for receiving a quality of service request (m₂) containing data concerning the input point of the packet flow associated with the request in the domain; a component for determining an output point corresponding to the request; and a transmitter for transmitting a modified request (m₃) to the access controller associated with the output domain corresponding to the output point, by inserting therein data concerning the input point of the packet flow in the output domain.
