GWN7000 User Manual

QoS
The GWN7000 offers the possibility to enable and configure QoS on WAN interfaces, this will help to
manage in more depth the network traffic to define priority and classify different services and protocols in
an efficient manner.
Also, the GWN provides the capabilities to configure advanced QoS features such as Active Congestion
Control (ACC) in order to avoid bottleneck on the network, especially when using VoIP.
Figure 16: QoS
To activate QoS, check “
Enable QoS
” option. Three tabs are available for configuration:
•
General
: Download and upload bandwidth speeds settings on each WAN interface as well as setting
the smart queue parameters which will allow to select the queuing mode on each wan interface. The
smart queue is an integrated network system that performs better per-packet/per flow network
scheduling, reduces the buffer bloat and keeps latency at acceptable levels. The users can from this
menu select which QoS mode to use on each WAN interface (either ACC, SQM or Legacy QoS).
•
Legacy QoS
: Legacy QoS allows creating Traffic Classes to prioritize traffic for specific resources on
the network by controlling transmission/upload rate. Note that different classes can be created and
assigned as Traffic filters by respecting following conditions:
✓
The total of Upstream bandwidth values of each created class should not exceed the upstream
bandwidth value configured in
General
.
✓
The remaining bandwidth will be lent to the next priority level of class.
✓
All filter options are summed together.
✓
While Upstream QoS is dealing with traffic transmission, Policer is controlling the incoming
traffic. Thus, allowing to create rules to specific targets to set priority and received traffic rate,
giving the GWN the ability to drop the exceeding traffic when reaching the max rate.
