All rights reservedFebruary 26-28, 2013 | Orlando, FL Upstream QoS (MU  WSP) Example Upstream transmission of Voice traffic from MU MU acquires the medium using the station EDCA configuration parameters advertised for the Voice category. MU can transmit multiple voice packets up-to TxOP limits advertised for Voice category MU sets a TID = 6 in the 802.11 frame header and marks the appropriate DSCP value in the IP header. Upstream processing on AP AP classifies the packet as WMM voice AC based on received TID = 6. AP applies any configured Diffserv policy rule in the upstream direction and if remarking is required based on match, DSCP value is updated. AP converts the 802.11 frame to a MVLAN tagged 802.3 frame with 802.1p priority derived from the DSCP-to-CoS map configured for the AP. AP encapsulates tagged 802.3 frame in CAPWAP header and copies the DSCP value of the encapsulated IP packet into the CAPWAP header. Upstream processing between AP and WSP The data-path between AP and WSP is trusted and the DSCP priority on the CAPWAP header is honored for packet forwarding on all intermediate switches WSP also treats the access tunnel as trusted and honors the DSCP value on the tunneled packet.

39. ©2013 Avaya Inc. All rights reservedFebruary 26-28, 2013 | Orlando, FL©2013 Avaya Inc. All rights reservedFebruary 26-28, 2013 | Orlando, FL Downstream QoS (WSP  MU) WSP receives IP packet with 802.1p and DSCP value and encapsulates the 802.3 tagged frame into CAPWAP tunnel header for forwarding towards AP. DSCP value of received IP packet is copied to CAPWAP header DSCP value of received IP packet may be remarked based on admin configurable rules on WSP. For non-IP packet ingress 802.1p-to-DSCP map is used to set the DSCP value on CAPWAP header. Switches/Routers between WSP and AP honor the DSCP value set on the CAPWAP header. AP extracts the tunneled tagged 802.3 frame and converts the frame to 802.11 frame for transmission to MU. DSCP value in the IP header can be remarked based on downstream Diffserv policy for the network. The access category for transmission of the frame on wireless medium is derived from DSCP- to-CoS table for the AP and CoS-to-WMM table for the MU’s wireless network. MU(s) packet is queued into the access category hardware queue derived from the CoS-to- WMM. (Note if the MU is in power-save mode, then packet is queued in a per-MU software queue) Radio hardware delivers the frame to the MU based on the AP EDCA parameters for the WMM access category
