The service quality problems faced by traditional networks are mainly caused by congestion. The impact of network congestion on services can be reduced through congestion avoidance and congestion management. Which of the following descriptions are correct? (Multiple choice)
- A . Congestion avoidance function can be implemented through tail drop or TRED
- B . Congestion management uses queue technology to cache messages in different queues, group different queues and apply scheduling algorithms to achieve differentiated processing of messages of different priorities.
