nating interface. Each packet is analyzed in an effort to match a defined
traffic class. The packet is then forwarded to the appropriate queue for ser-
vicing.
Classes are defined by parameters called class characteristics.
Examples of class characteristics are bandwidth, weight, and maximum
packet limit. The bandwidth assigned is the minimum bandwidth required
for that specific class of service during periods of congestion. The weight
value is derived from the bandwidth value assigned to each class. In addi-
tion, the weight value is used to help calculate the average queue length ...
