LAN/WLAN
Managed
Downstream
Bandwidth
Enter the amount of downstream bandwidth for the LAN and WLAN that
you want to allocate using QoS.
The recommendation is to set this speed to match the WAN interface’s
actual downstream speed. For example, set the WAN interface speed to
100000 kbps if your Internet connection has a downstream transmission
speed of 100 Mbps.
You can set this number higher than the interface’s downstream speed.
The Device uses up to 95% of the DSL port’s actual downstream speed
even if you set this number higher than the DSL port’s actual
downstream speed.
You can also set this number lower than the WAN interface’s actual
downstream speed. This will cause the Device to not use some of the
interface’s available bandwidth.
If you leave this field blank, the Device automatically sets this number
to be 95% of the DSL port’s actual downstream speed.
Upstream
traffic priority
will be
automatically
assigned by
Select how the Device assigns priorities to various upstream traffic
flows.
• None: Disables auto priority mapping and has the Device put
packets into the queues according to your classification rules. Traffic
which does not match any of the classification rules is mapped into
the default queue with the lowest priority.
• Ethernet Priority: Automatically assign priority based on the IEEE
802.1p priority level.
• IP Precedence: Automatically assign priority based on the first
three bits of the TOS field in the IP header.
• Packet Length: Automatically assign priority based on the packet
size. Smaller packets get higher priority since control, signaling, VoIP,
internet gaming, or other real-time packets are usually small while
larger packets are usually best effort data packets like file transfers.
