When the wired side detects a security issue with the wireless terminal, the linkage mechanism will be triggered to notify the wireless controller to block the terminal's wireless access, thereby ensuring network security.
Air interface optimization and terminal access strategy
• Support Radio Resource Optimization Policy (RROP), which refers to a collection of various wireless air interface optimization methods aimed at reducing or controlling the consumption of air interface media resources by management messages, broadcast messages, and invalid messages, leaving more resources to provide users with better wireless application services. RROP mainly includes air interface optimization strategies such as wireless service layer 2 isolation function, disabling low rate, adjusting Beacon transmission time interval, and disabling broadcast probe detection function.
• Support Station Access Control Policy (SACP), which restricts, controls, and guides wireless terminal access to better APs or wireless services; And control and schedule terminal traffic based on network applications, improve the overall performance of the wireless network, and enhance the experience and effectiveness of wireless access applications. SACP mainly includes terminal control strategies such as prohibiting weak signal client access, spectrum navigation, roaming navigation, load sharing, ignoring weak signal strength messages, fair scheduling of air interface transmission, traffic shaping based on client link conditions, and intelligent bandwidth guarantee.
RF resource management
RRM (Radio Resource Management) uses systematic intelligent radio frequency management to monitor real-time environmental issues such as channel utilization, channel interference, and signal conflicts of the air interface. It adjusts the working channel, bandwidth, power, and other parameters of the radio frequency in a timely manner to maintain the optimal state of radio frequency resources. It can achieve automatic network deployment and automatic network repair.
application support
New H3C uses its unique Wi Fi 6 eXtreme Plus technology to intelligently identify users' applications on the AP, and saves snapshots of the identified applications. Users' subsequent messages will be compared with the snapshots. Combined with intelligent sorting technology, the identified application messages can be processed at high speed, overcoming the problems of low DPI performance and inaccurate DFI identification of applications in traditional methods. When the AP detects that the user is using critical services, it will optimize the roaming and RF switching behavior in a targeted manner, ensuring that the user maintains a smooth experience while using critical services. When it is found that the high occupancy rate of the air interface affects the user experience of audio and video services, the AP jointly mobilizes priority to ensure the traffic of key services, reserves air interface resources for key services, and achieves the effect of bidirectional acceleration of applications.
Support roaming optimization
Wireless APs fully support the Fast BSS Transition function defined in the 802.11r standard, which can accelerate the roaming process of wireless users, reduce the probability of connection interruption, and improve the quality of roaming services.
Through the 802.11k protocol mechanism, AP and wireless clients perform interactive detection and perceive network topology from multiple dimensions; AC full view recognition and comprehensive calculation of wireless client roaming timing and roaming access location, negotiating handover with the client through 802.11v and 802.11r mechanisms; During the simultaneous switching period, AC ensures traffic maintenance for downstream business traffic, thereby achieving seamless switching and improving user experience.
Only 11ax access
Supports Only 11ax access function, as Wi Fi 6 (802.11ax) is backward compatible with the 802.11a/b/g/n/ac protocol, 802.11a/b/g/n/ac users can usually access Wi Fi 6 (802.11ax) wireless access devices. However, the provision of this compatibility capability will result in a certain degree of decline in the actual performance of users with high access capabilities such as Wi Fi 6 (802.11ax). H3C devices support setting a certain RF of wireless access devices to Only 11ax access mode, allowing only Wi Fi 6 (802.11ax) users to access, ensuring bandwidth and performance.
Support probe scanning
The product can be used as a sensor device for remote probe analysis, with independent scanning of radio frequency. Without affecting the normal access and use of AP, it can listen, capture and real-time mirror the full frequency Wi Fi messages within the coverage area to the local analysis device for network administrators to troubleshoot and optimize analysis. The remote probe analysis function can not only mirror wireless messages for the working channel, but also poll and sample all channels, flexibly meeting the requirements of wireless network monitoring and operation,
The product can simulate wireless terminals and cooperate with intelligent operation and maintenance platforms to analyze and troubleshoot wireless air interface faults, that is, Doctor AP mode. This mode AP will simulate terminal behavior, collect wireless network information, and synchronize it to the intelligent operation and maintenance platform for accurate diagnosis. Cooperate with Cloudnet APP and Yunjian to achieve three-dimensional analysis of cloud network end and accurately locate wireless network problems.
Support OFDMA technology
Support OFDMA (Orthogonal Frequency Division Multiple Access) technology, AP can segment wireless bandwidth and transmit data to multiple terminals using different subcarriers at the same time, reducing the delay caused by multi-user air interface resource conflicts and backoff in traditional protocols, and improving the user experience of low latency applications such as voice and video in multi-user scenarios.
Support spatial reuse technology
Support SR (Spatial Reuse) technology and BSS Coloring mechanism, control the terminal to adjust the transmission power by recognizing the message color at the link layer, improve the channel multiplexing capability during high-density deployment, alleviate the problem of same channel interference during multi-user use, and significantly improve the utilization of spectrum resources.
Support TWT technology
Support TWT (Target Wake Times) technology, allowing APs to uniformly schedule the wake-up and sleep of terminals. This not only reduces conflicts between terminals, but also reduces unnecessary wake-up times, achieving energy-saving goals.
Flexible forwarding strategy
When connected through a wide area network, wireless access devices are deployed at branch offices, while wireless controllers are deployed at headquarters. The traditional forwarding mode is that data packets are sent from the wireless access devices to the wireless controllers, and then centrally forwarded by the wireless controllers. The product can directly convert data packets into wired format packets on wireless access devices, allowing data packets to be forwarded locally without passing through wireless controllers, greatly saving wired bandwidth. At the same time, it also supports flexible policy forwarding, allowing terminals within wireless services to achieve traffic concentration and local forwarding selection based on forwarding policies, thereby releasing the pressure of export bandwidth and reducing network bandwidth costs.
Supports IPv4/IPv6 dual stack (Native IPv6)
Fully supporting IPv6 features, the device implements IPv4/IPv6 dual protocol stack. Regardless of whether the original wired network is IPv4 or IPv6, it can automatically register and provide WLAN services on the wireless controller through broadcasting, multicast, DHCP option43, DNS, and other methods, without becoming an information island in the network.
