Planning Considerations - Voice • Define voice applications and handsets • 802. 11 a, 802. 11 n, interoperability tested? • Coverage area • Which areas of the WLAN network need to support voice • Anticipate mobile nature of users & devices / Roaming requirements • RF audit and site survey: • RF isn’t simple – every building is different • Pre & post site surveys are the only way to ensure the best possible deployment • Auto-channel and auto-power can’t overcome poor AP placement • For voice, APs should be deployed for density (versus range) © 2013 Avaya Inc.

1. Packet Prioritization (end-to-end) • Purpose • Recognize high priority packets • Minimize latency and ensure timely delivery High Queue Video AC (VI) • Without Prioritization? • All packets have equal access to the wireless network which may delay voice packets, resulting in poor audio quality © 2013 Avaya Inc.

2. Timed Delivery • Purpose • Provide devices with pre-determined ‘rest’ periods in order to: • Conserve power ; Scan neighboring APs; Roam to better signal AP • Without Timed Delivery? • Devices must be awake at all times to ‘wait’ for traffic • Resulting in less battery life • Devices may miss packets during roaming • Resulting in poor audio quality 19 © 2013 Avaya Inc. All rights reserved 19 February 26 -28, 2013 | Orlando, FL
3. Admission Control • Purpose • Allocates available bandwidth for associated devices based on traffic requirements • Avoids network saturation • Without Admission Control? • Access Points (AP) may become oversubscribed, resulting in poor a audio quality for all voice devices 20 © 2013 Avaya Inc.

Upstream Qo. S (MU WSP) Example • Upstream transmission of Voice traffic from MU • • Upstream processing on AP • • • MU acquires the medium using the station EDCA configuration parameters advertised for the Voice category. MU can transmit multiple voice packets up-to Tx. OP 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. 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. 1 p priority derived from the DSCP-to-Co. S 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. © 2013 Avaya Inc. All rights reserved February 26 -28, 2013 | Orlando, FL
Downstream Qo. S (WSP MU) • WSP receives IP packet with 802. 1 p and DSCP value and encapsulates the 802. 3 tagged frame into CAPWAP tunnel header 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. 1 p-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 -Co. S table for the AP and Co. S-to-WMM table for the MU’s wireless network. MU(s) packet is queued into the access category hardware queue derived from the Co. S-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 © 2013 Avaya Inc.
