24.1. Overview
ASWipLL provides end-to-end Quality of Service (QoS) for the ASWipLL network.
This proprietary QoS relates to internal traffic between the BSR and SPR. Once
traffic exits to the WAN, the original QoS settings of the packet are used (except for
QoS for IP addresses).
Configuring QoS for SPRs and BSRs are similar. The only difference is that QoS for
BSR is pertinent to downlinks (i.e. traffic from BSR to SPRs associated with the
BSR); QoS for SPR is pertinent to uplinks (i.e. traffic from the SPR to the BSR).
Thus, in most cases, you need to configure QoS for both the BSR and SPR. A
scenario where QoS is configured only at one end is for trivial file transfer protocol
(TFTP) traffic, which is configured only at the BSR (i.e. downlink traffic from BSR
to SPR.) This allows you to ensure high priority for traffic (i.e. TFTP traffic)
concerned with downloading software versions to ASWipLL devices.
The figure below illustrates an example of QoS settings between a BSR and an SPR,
where VoIP traffic is assigned highest priority.

Note: When setting QoS for a specific IP address, QoS for BSR is according
to source (i.e. from WAN); QoS for SPR is according to destination (i.e. to
WAN).
