HH3C-DOT11-QOS-MIB
This MIB provides information about WLAN QoS configuration. GLOSSARY IEEE 802.11 Standard to encourage interoperability among wireless networking equipment. WMM WMM is a wireless QoS protocol designed to preferentially transmit packets with high priority, thus guaranteeing better QoS services for voice and video applications in a wireless network. EDCA Enhanced distributed channel access (EDCA) is a channel contention mechanism designed by WMM to preferentially transmit packets with high priority and allocate more bandwidth to such packets. AC Access category (AC), is used for channel contention. WMM defines four access categories; they are AC-VO (voice), AC-VI (video), AC-BE (best-effort), and AC-BK (background) in the descending order of priority. When contending for a channel, a high-priority AC preempts a low-priority AC. CAC Connection admission control (CAC) limits the number of clients that are using high-priority ACs (AC-VO and AC-VI) to guarantee sufficient bandwidth for existing high-priority traffic. U-APSD Unscheduled automatic power-save delivery (U-APSD) is a new power saving mechanism defined by WMM to enhance the power saving capability of clients. SVP SpectraLink voice priority (SVP) is a voice priority protocol designed by the Spectralink company to guarantee QoS for voice traffic.
