Abstract
A stage-implemented QoS shaping scheme is provided for a data communication switch. The stage-implemented QoS shaping scheme may be implemented by augmenting an existing packet forwarding logic. Inbound packets or other input signals enter the switch with inbound QoS or priority information. The inbound QoS information and packet header data are used by the switch to determine internal and outbound QoS information in stages. The first stage receives a key including addressing and other information and determines a QoS shaping index. In the second stage, the QoS shaping index is used to select QoS shaping maps, and the inbound QoS information is mapped to the QoS shaping maps to select internal and outbound QoS information.
