QOS Classification This feature provides the capability to partition network traffic into multiple
priority levels or classes of service. After packet classification, other QOS
features can be utilized to assign the appropriate traffic handling policies
including congestion management, bandwidth allocation, and delay bounds
for each traffic class.
Possible responses are:
Best Effort (BE)
Assured Forwarding (AF1)
Assured Forwarding (AF2)
Assured Forwarding (AF3)
Assured Forwarding (AF4)
Expedited Forwarding (EF)
Network Control (NC)
Peak Information Rte (%) The maximum allowed rate for this priority, expressed as a percentage of
the DSL rate.
Committed Information Rate (%) The committed rate for this priority, expressed as a percentage of the DSL
rate.
Peak Burst Size The interval in milliseconds for averaging the peak offered rate.
Committed Burst Size The interval in milliseconds for averaging the committed offered rate.
Max Queue Size The number of packets that can be queued for this priority.
Latency Measurements
Latency Boundary This configures the maximum latency boundary in milliseconds that a
specific packet may be delayed by.
Latency Threshold (ms) This setting configures the maximum latency boundary in milliseconds that
a specific packet may be delayed by.
Possible responses are:
Boundary 1:0 ms
Boundary 2:10 ms
Boundary 3:30 ms
Boundary 4:40 ms
Boundary 5:100 ms
Boundary 6:1000 ms
Boundary 7:3000 ms
IP Fragmentation Enable Factory Default = DISABLED
If this box is checked, IP Fragmentation will be Enabled. If Enabled and
packets larger than 1500 bytes total are received, they will be fragmented.
IP Fragment Size This is the IP Packet Size.
Possible responses are:
100, 148, 244, 292, 340, 388, or 436
If you made changes to the QOS Configuration and clicked on save, the following screen will be displayed. Click
