Q.
What are the appropriate WAN inbound/outbound bandwidths you
had better to set in QoS settings ?
The WAN inbound/outbound bandwidths are set according to the
actual transmission rate offered by ISP, but the real throughput
depends on the local network environment or quality of infrastructure.
Therefore the inbound/outbound bandwidths are recommended
to set 80-85% of physical network speed to maximize the QoS
performance.
Take DrayTek Vigor Router for instances:
- When using Vigor2900 Broadband Router,
if the bandwidth that ISP offered is with downspeed 8Mbps
and upspeed 640Kbps, the QoS WAN Inbound/Outbound bandwidths
we suggest are
WAN Inbound Bandwidth = 8000 * 80% (or 85%)= 6400 ~ 6800 Kbps
WAN Outbound Bandwidth = 640 * 80% (or 85%)= 512 ~ 544 Kbps
- When using Vigor2600V ADSL Router, Vigor
itself will auto-detect the bandwidth and count the appropriate
value. |
