1
Classification—Packets are classified and marked according to policies and traffic behavior. This is
accomplished on the ingress using technologies, such as 802.1p, IP precedence and Diffserv Code Point
(DSCP). See "Classification" on page 21-6
2
Congestion Management—Classified packets are prioritized and funneled from ingress to egress
using queuing technologies, such as Class of Service (CoS) VOQs, to ensure preferential treatment to high
priority traffic. See "Congestion Management" on page
3
Congestion Avoidance—Weighted Random Early Detection (WRED) is used for admission control
and bandwidth management. Packets that are not high priority are randomly dropped to help avoid "tail
drop" on the queues. See
4
Traffic Policing and Shaping—Packet flows are policed or shaped to limit the rate of traffic received
or sent by the switch. See
OmniSwitch AOS Release 7 Network Configuration Guide
for more information.
