DESCRIPTION
Select the Enable check box to turn on QoS to improve your network
performance.
Enter the amount of upstream bandwidth for the WAN interfaces that you want to
allocate using QoS.
The recommendation is to set this speed to match the interfaces' actual
transmission speed. For example, set the WAN interfaces' speed to 100000 kbps
if your Internet connection has an upstream transmission speed of 100 Mbps.
You can set this number higher than the interfaces' actual transmission speed.
The VDSL Router uses up to 95% of the DSL port's actual upstream transmission
speed even if you set this number higher than the DSL port's actual transmission
speed.
You can also set this number lower than the interfaces' actual transmission
speed. This will cause the VDSL Router to not use some of the interfaces'
available bandwidth.
If you leave this field blank, the VDSL Router automatically sets this number to
be 95% of the WAN interfaces' actual upstream transmission speed.
Enter the amount of downstream bandwidth for the LAN interfaces (including
HPNA and WLAN) that you want to allocate using QoS.
The recommendation is to set this speed to match the WAN interfaces' actual
transmission speed. For example, set the LAN managed downstream bandwidth
to 100000 kbps if you use a 100 Mbps wired Ethernet WAN connection.
You can also set this number lower than the WAN interfaces' actual transmission
speed. This will cause the VDSL Router to not use some of the interfaces'
available bandwidth.
If you leave this field blank, the VDSL Router automatically sets this to the LAN
interfaces' maximum supported connection speed.
Select how the VDSL Router assigns priorities to various upstream traffic flows.
•
None: Disables auto priority mapping and has the VDSL Router 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.
