IP QoS
Before attempting to configure IP QoS, you will need a good understanding of the TCP/IP
protocol and ports.
The IP Quality Of Service (QoS) queues data streams to ensure that basic connectivity is
maintained when running multiple services over one connection. For example, if you are
using a peer-to-peer file-sharing program whilst simultaneously performing normal web
browsing, you can configure QoS to limit the resources dedicated to the peer-to-peer
session to ensure web browser connectivity. IP QoS is often critical to maintain VoIP
session quality.
IP QoS services in the iConnectAccess624W are applicable to the output device (LAN
side). This means that the IP QoS is associated with any transmitted traffic from the
iConnectAccess624W. Each output device has three priority queues associated with
transmit data. The High priority queue has strict priority over medium and low priority
queues. The Medium and Low priority queues are serviced on a round robin priority
basis according to the configured weights (WRR), after the High priority queue has been
completely serviced.
NOTE:
If IP QoS is enabled and no rules are defined, a default rule is added
which is hidden. The default rule places all traffic to be transmitted in the
Low priority queue.
To Configure IP QoS:
From any screen in the web interface,
step 1
Click the Advanced tab, then IP QoS. The following screen appears:
step 2
Select a WAN connection to enable IP QoS for the modem’s upstream
traffic, or choose a LAN connection (Ethernet and USB Bridged) for the
downstream traffic, from the Choose a connection drop-down list.
