Propagation of Quality of Service (QoS) management through a heterogenous network
A network access device is configured to propagate Quality of Service (QoS) management through a heterogenous network. A Mirrored Stream Classification Service (MSCS) setup request having MSCS information or MSCS information that is proxied to a next hop in an uplink is received. The MSCS information identifies at least one traffic flow associated with a first user priority. A downlink rule is generated that matches the first user priority in the MSCS information in the uplink to a downlink traffic flow. The downlink rule is used to analyze the downlink traffic flow to match the MSCS information in the downlink that is the mirror of the MSCS information in the uplink. The user priority is applied to the downlink that mirrors the MSCS information in the uplink.

7. The network access device of claim 1 , wherein the next hop in the uplink comprises an AP, the AP receiving the MSCS setup request marked with a Quality of Service (QoS) to apply to a traffic flow in a downlink having the MSCS information in the downlink that is a mirror of the MSCS information in the uplink.

applying the user priority to the downlink that mirrors the MSCS information in the uplink; and
mapping the first UP to Wi-Fi Multimedia-Access Categories (WMM-AC).
10. The method of claim 9 , wherein the receiving one of the Mirrored Stream Classification Service (MSCS) setup request having MSCS information or the MSCS information that is proxied to the next hop in the uplink comprises receiving a station (STA) source MAC address, the first UP, and a template of fields for creating at mirrored classifier to apply to downlink traffic to the STA source MAC address with the first UP.
11. The method of claim 9 , further comprises dynamically generating the downlink rule is performed when a packet in an uplink is received that matches the first user priority, applying fields from a template provided by the MSCS information to apply to the downlink traffic flow and using the first user priority for the downlink traffic flow.
