Manage 802.11ax Access Points

In addition to managing 802.11a/b/g/n/ac access points, the WX3800H series access controllers can work with H3C 802.11ax access points, providing wireless access at speeds several times faster than traditional 802.11a/b/g/n/ac networks. The increasing proliferation of 802.11ax devices will make the functionality of multimedia applications on wireless networks a reality.

A completely new operating system

The WX3800H series access controllers are based on the latest H3C V7 platform. The new system demonstrates significantly improved performance and reliability compared to the previous version and is capable of supporting increasingly complex network applications in enterprise networks. The V7 platform has the following advantages:

Multi-core control: The V7 platform allows you to adjust the ratio between the number of processor cores allocated to control functions and the number of cores allocated to functions forwarding to maximize the use of processor resources and achieve the desired balance between control and forwarding functions, providing powerful parallel multiprocessing capabilities.

Multitasking at the user level: in the platform V7 introduces a completely new software privilege management system in which most network applications are executed at the user level, allowing each application to run as a separate task. Each task is allocated its own resources, and failures in the execution of a task are isolated at the level of a separate space for this task, without affecting the execution of other tasks. This significantly increases the security and reliability of the system.

User task monitoring: The V7 platform provides a task monitoring function that allows you to track the execution of all tasks. If a user task fails, the system reboots it to restore the application as quickly as possible.

New independent application update mechanism: The V7 platform supports independent application update, allowing It is possible to update a separate application module, rather than the entire operating system. This significantly reduces the number of required system reboots compared to the previous version, without compromising the security of updates and maintaining network stability.

Capabilities for processing wired and wireless segments

The WX3800H series access controllers utilize the latest high-performance multi-core processors. The WX3840H access controller processor has 8 independent cores that support virtualization of up to 32 logical cores, while the WX3820H access controller processor has 4 independent cores that can virtualize up to 16 logical cores. High processing power allows devices to serve more users, more concurrent operations, and reduce latency for a better user experience.

High access port density

The WX3800H series access controllers feature high port density for external access. This allows for better unification of access control mechanisms for wired and wireless networks (through integrated user management of wired and wireless networks, including user access control, user authentication and charging management), meeting modern networking and access control requirements.

The WX3820H model is equipped with 8 combined GE ports and 2 SFP+ 10G ports;

The WX3840H features 8 combo GE ports, 2 SFP+ 10G ports, and 1 management port. The management port is designed to support out-of-band management.

IRF hot standby

The WX3800H series access controllers feature intelligent technology Intelligent Resilient Framework (IRF) architecture developed by H3C. The IRF model virtualizes multiple devices as a single distributed device, which provides the following benefits:

Easy network management: IRF does not require separate cables and stacking ports, stacking is created after connecting devices at layer 2.

Functional stacking: an IRF group is virtualized into one access controller, with the number of managed users and access points equal to the capacity of individual controllers access.

Easy to configure: configuration changes made to the virtual access controller are automatically synchronized with other physical access controllers.

Exceptionally reliable redundancy: supports 1+1 hot standby, which means hot standby of all applications, while the failure of one of the access controllers does not affect the functioning of the virtual access controller. The WX3800H series access controllers support stacking of up to two devices.

Flexibility of license management: A license installed on one of the devices in the IRF group can be used by other devices, while the number of access points connected to the virtual access controller , equal to the sum of licenses available on physical access controllers; despite the fact that licenses are installed and tied to a separate device, downloading and migrating licenses becomes more convenient.

Hierarchical architecture of access controllers

Hierarchical Access Controller Architecture is a new network configuration scheme developed by H3C engineers to solve the multi-layer networking challenge demanded by the market. The access controller hierarchy design uses a centralized management hierarchy similar to that used by large enterprises, where one access controller at the core network level communicates with several local access controllers at the access network level, which in turn communicate directly with the access points. Access controllers at the access network level serve primarily real-time applications, such as access to an access point and forwarding data, while access controllers at the core network level primarily perform non-real-time tasks, such as control plane control and centralized authentication, but can still perform the typical access point connectivity and data forwarding functions of standard access controllers. Core layer access controllers are high-performance access controllers that are located at the convergence layer; Access network level access controllers can include standard access controllers, all-in-one access controllers (combining router and deep packet analysis functions), and wired and wireless access controllers installed in parallel with the existing network. The hierarchical access controller model takes the integration of wired and wireless networks to a new level and can be used to create large wireless networks. The hierarchical access controller model is a natural fit for the headquarters-branch deployment design, with core network throughput and core access controller forwarding performance no longer being the bottleneck. The centralized management functions of core network layer access controller, access network layer access controllers and low-level access points can be conveniently updated and automatically synchronized, greatly simplifying system upgrades. Access network layer access controllers are responsible for switching access points and significantly improve roaming performance.

CUPID-based wireless location determination

H3C CUPID technology is a highly accurate location determination technology using wireless local area network WLAN. It has the following advantages and capabilities:

High accuracy

Traditional technology for determining location by triangulation and characteristic fingerprints is based on received signal strength (RSSI), and its accuracy is inevitably affected by fluctuations in the RSSI power level. Different types of interior decoration and the random nature of user traffic lead to changes in RSSI data. H3C’s CUPID location technology combines information from Atheros chips and the wireless network for more accurate positioning, overcoming the limitations of RSSI location systems. Under good conditions, the error in position determination can be only 3-5 meters.

Small delay

CUPID offers lower latency compared to traditional signal strength-based technology. Because it uses information actively received from access points, the latency in determining the location is less than 2 seconds, which significantly improves the efficiency of signal acquisition and data collection.

Lack ofpreliminary< strong>collectionspecimens

In traditional fingerprint-based location technologies, significant time and resources are spent on collecting samples, with any change in the configuration of the deployed network such as changing the antenna or access point position, this procedure must be repeated. This adversely affects the performance of the location system. CUPID-based location detection eliminates sample collection, so that access points can be included in location immediately using the existing network configuration. Additionally, CUPID supports deployment across multiple channels. Each channel can use up to six spectral functions, which allows you to suppress interference within the same spectrum and improve positioning accuracy.

Flexible forwarding modes

In a wireless network with a centralized forwarding mode, all wireless network traffic is sent to the access controller for processing, and therefore the forwarding performance of the access controller can become a bottleneck. This is especially true in wireless network configurations in which access points are installed in branch offices and access controllers are installed in headquarters, while the connection between access points and access controllers is carried out over a distributed WAN network. In this configuration, distributed forwarding mode is better suited. The WX3800H series access controllers support both distributed and centralized forwarding modes, and can perform SSID-based forwarding as needed.

Carrier-grade wireless user access management and control functions

User-level access control is one of the main functions of the WX3800H series access controllers. The WX3800H series access controllers provide user profiles that can serve as configuration templates for predefined settings. Depending on the applications used, you can configure various settings in the user profile, such as guaranteed access rate (CAR) and quality of service (QoS) management policy.

During the authentication process, the authentication server assigns a user profile to the device. If the user is authenticated, the values
