We adopt the queuing technology for congestion management generally. If we use queue algorithm for traffic
classification, then we use a kind of priority algorithm to send out the traffic. Each queue algorithm is used for

The processing of congestion management includes the queue creation, packet classification, sending different
packet to different queue, queue scheduling.
