Abstract
A method and a semiconductor intellectual property embodiment of the present invention comprise a class-based queue traffic shaper that enforces multiple service-level agreement policies on individual connection sessions by limiting the maximum data throughput for each connection. The class-based queue traffic shaper distinguishes amongst datapackets according to their respective source and/or destination IP-addresses. All limit checking is done in one clock cycle for the entire network hierarchy above a particular node, and previously independent and separate queues are combined into one super queue.
