What is the function of the WLAN QoS profile

12

The QoS profile defines the local priority and CAR. The WLAN QoS profile is bound to a user group. After WLAN users are authenticated successfully, the RADIUS server delivers authentication information containing the user group name to the AC. The AC delivers QoS CAR to the AP to limit STA data packets.

What are functions of a WRED drop profile
The WRED drop profile has the following functions: - By default, the AR uses the tail drop mechanism. The AR discards data packets at the end of a queue when congestion occurs until the congestion problem is solved. The tail drop mechanism causes global Transmission Control Protocol (TCP) synchronization and reduces link usage. To solve the problem, configure the Weighted Random Early Detection (WRED) WRED in queues. - You can use a WRED drop profile to configure different drop probability values based on priorities so that the AR first discards low-priority packets and ensures requirements of high-priority and low-delay services.

What functions do drop profiles have
Drop profiles have the following two functions: -By default, AR series routers use the tail drop method and discard data packets at the end of a queue when congestion occurs. The tail drop method causes global Transmission Control Protocol (TCP) synchronization and reduces link usage. Drop profiles and the Weighted Random Early Detection (WRED) can solve this problem. -By configuring different priority-based drop probabilities in drop profiles, you can ensure that packets with a low priority are dropped preferentially, and ensure the quality of high-priority and low-delay services.

Functions supported by the QoS technology
In a high bandwidth consuming network, quality of service (QoS) can properly allocate limited bandwidth resources by service type. In case of network congestion, QoS preferentially guarantees committed bandwidth for important services to ensure their availability. In a network that has sufficient bandwidth, the QoS technology is not required.

What are WLAN reliability features
- Dual link mechanism To improve AC reliability, two ACs can be deployed to implemented dual-link backup. When the active AC fails or the CAPWAP tunnel between an AP and the active AC fails, service traffic of the AP can be switched to the standby AC to e
