802.11ac AP Management

In addition to 802.11a/b/g AP management, the WX3500H series AC can work together with H3C 802.11ac-based APs to provide wireless access speed several times faster than a traditional 802.11a/b/g network. With 802.11ac large proximity which makes WLAN multimedia applications deployment a reality.

Brand New Operating System

WX3500H series AC is developed based on the latest H3C V7 platform. The new system sports significantly improvements in performance and reliability over the previous version, and is able to run the increasingly complicated network applications in the enterprise market. V7 features the following advantages:

Multi-core control: V7 can adjust the ratio of control cores to the forwarding cores in the CPU to make the most out of CPU computing power and strike the balance between control tasks and forwarding tasks, while providing strong concurrent computing power.

User mode multi-tasking: V7 adopts a completely new software privilege level system, where most network applications are executed in user mode, and allow each application runs a different task. Each task has its own dedicated resource and when a task fault occurs which will be isolated at its own space avoiding interruption of other tasks. This makes system run more securely and reliably.

User task monitoring: V7 comes with task monitoring feature, in which all tasks are monitored. When a user task goes wrong, system will reload and application will quickly recover.

New independent application upgrade: V7 supports independent application upgrade, where a single application module is upgraded instead of the whole operating system. This greatly reduces the number of system reboots compared with the previous version, keeping the upgrade secure and sustaining the network stability.

Strong Wired and Wireless Processing Capability

WX3500H series AC adopts the latest high performance multi-core CPU. WX3540H AC CPU possesses 8 independent cores that can be virtualized to 32 logical cores, while WX3510H and WX3520H series ACs have 4 independent cores that can be virtualized to 16 logical cores. The strong computing power allows the devices to handle more users, more concurrent transactions, decrease latency in order to improve user experience.

High Port Density for Access

WX3500H series AC provides high port density for external access. This results in better unified wired and wireless access (integrated wired and wireless user management including user access, user authentication and billing management) and satisfy network construction and access requirements.

WX3510H provides 8 GE Combo ports;

WX3520H provides 8 GE Combo and 2 10G SFP+ ports;

WX3540H provides 8 GE Combo, 2 10G SFP+ ports and 1 management port. The management provides out-of-band management capability.

Star IRF Support

WX3500H series AC supports a new star IRF (Intelligent Resilient Framework) developed by H3C. Compared with traditional IRF models, new star model employs layer 2 network (virtualized as a central node) to connect multiple devices, which makes network construction more flexible. The rationale behind the star IRF model is to connect multiple devices in star topology and virtualized as a single distributed device, which possesses the following advantages:

Simple network configuration: star IRF does not require dedicated stack cables and ports, the stack is created once they are connected in layer 2

Capability stacks: star IRF appears to be a single virtualized AC, with the number of users and APs managed equal to individual ACs' capacity added together

Simple configuration: configuration changes made to the virtual AC will automatically synchronized to all physical ACs

Highly reliable backup: supports M+N hot backup, meaning all applications have backups, and a single AC failure will not affect the functioning of virtual AC. WX3500H series AC supports a maximum of two-device stack

Flexible license control: A license installed in one device of a star IRF can be shared by other devices, number of APs that can be connected to the virtual AC is the sum of licenses possessed by all physical ACs; although licenses are installed and tied to individual device, unload and migration becomes more convenient

Layered AC Architecture

Layered AC architecture is the brand new network configuration engineered by H3C to cater for the need of multi-layer network construction in the market. Layered AC employs the centralized management hierarchy similar to the large enterprise, where one core layer management AC associates with multiple local access layer ACs, and access layer ACs directly connects with underlying APs. Access layer ACs' mainly serve real-time applications such as AP access and data forwarding, while core layer ACs' mainly focus on non-realtime tasks such as management control and centralized authentication, and still retain the functions of connecting APs and forwarding data that typical ACs have. Core layer ACs are high performance ACs and are deployed in the convergence layer; access layer ACs can be comprised of standard ACs, all-in-one ACs (with router and DPI features), or wired and wireless ACs, and are deployed in parallel with existing network. Layered AC network construction model puts wired and wireless integration to the next level, and is applicable to large scale wireless network construction. Layered AC model maps naturally to the head quarter and branch deployment scenario, where core link bandwidth and core AC forwarding power no longer become a bottleneck. Core layer AC centralized control, access layer AC and lower level APs can be conveniently upgraded and synchronized automatically, and greatly simplifies version upgrade tasks. Access layer AC will be responsible for AP switching and significantly improves roaming performance.

CUPID Wireless Positioning

H3C CUPID is a highly precise wireless positioning technology based on WLAN environment. It has the following advantages and features:

I. Highly precise

Traditional triangular and fingerprint positioning is based on Received Signal Strength Indicator (RSSI) power, and its precision is inevitably affected by RSSI power level fluctuation. Indoor decorations and the random nature of customer traffic will cause perturbation in RSSI data. H3C CUPID based positioning technology integrates information from Atheros chips and WLAN to make indoor positioning more precise, and overcome the limitation of RSSI based positioning systems. The positioning error could be as little as 3-5 meters under good conditions

II.Low latency

CUPID has lower latency compared with traditional signal based positioning technology. As it is based on active information compiled from the Access Point, its delay can be limited to within 2 seconds, and significantly improve the efficiency in signal and data collection

III.No pre-sampling

Traditional fingerprint based positioning requires substantial time and resource in sampling, and re-sampling is needed whenever changes are made to the deployment configuration, such as AP antenna or position. This creates considerable impact to the positioning system performance. CUPID positioning can skip the sampling process and the AP can start positioning right away with existing deployment configurations. CUPID also supports cross-channel deployment. Each channel could be deployed in up to six spectra, this would suppress interfaces in the same spectrum and improve positioning precision

Flexible Forwarding Modes

In a wireless network of centrailized forwarding mode, all wireless traffic is sent to an AC for processing. Therefore, the forwarding capability of the AC may become a bottleneck. This is especially of the AC may become a bottleneck. This is especially true on wireless networks where Aps are deployed at branches, AC are deployed at the headquarters, and Aps and ACs are connected over a WAN. However, distributed forwarding cannot provide traffic control as good as the centralized forwarding mode does. The WX3500H series AC supports both forwarding modes. You can set SSID based forwarding as needed.

Carrier-Class Wireless User Access Control and Management

User-based access control is a key feature of WX3500H series AC. The WX3500H series AC comes with a user profile that serves as a configuration template to save predefined configurations. For different application scenarios, you can configure different items in a user profile, such as Committed Access Rate (CAR) and QoS policies.

During authentication, an authentication server assigns a user profile to the device. If the user passes authentication, the device uses the configuration contents in the user profile to restrict the accessibility of resources of the user. When the user goes offline, the device disables the user profile. Thus, user profiles are applicable to online users rather than offline users and users that fail to pass authentication.

The WX3500H series AC also supports MAC-based access control, which allows you to configure and modify the access rights of a user group or a particular user on an AAA server. The refined user rights control method enhances the availability of WLANs and facilitates access right assignment.

MAC-based VLAN is another strong feature of the WX3500H series AC. The administrator can assign users (or MAC addresses) with the same attributes into the same VLAN and configure a VLAN-based security policy on the AC. This simplifies system configuration and refines user management to the per-user granularity.

For security or accounting, the administrator may need to control the physical positions of wireless clients. The WX3500H series can satisfy this requirement. During authentication, the AC gets a list of permitted APs from the authentication server and then selects an AP for the requesting wireless client. In this way, the wireless client can only associate with that AP and thus its position is controlled.

New Wireless Intelligent Application Aware (wIAA)

Wireless Intelligent Application Aware Feature (wIAA) provides a user role based application layer security, QoS and forwarding policy for wired and wireless users. With wIAA, administrator can specify websites users’s browsing, application protocols (HTTP, FTP) they use and bandwidth they are allocated. Compared with V5 AC, the V7 AC comes with Deep Packet Inspection (DPI) capability, expanding application detection and detailed statistics. Previous V5 AC detection was based on layer 4 Ethernet protocol (e.g. 80 maps to HTTP, 20/21 maps to FTP, 8000 maps to QQ and so on), which can be easily circumvented by agents while the new V7 AC is based on layer 7 characteristics of Ethernet protocols, as well as the typical packet signature to implement a more precise recognition and complete restriction. With DPI, administrator can instead of prohibiting user visit all e-commerce websites but to set restriction on a per-website basis (such as JD, Taobao, Yihaodian). This simplifies configuration and improves productivity.

Intelligent Channel Switching

In a WLAN, adjacent wireless APs should work in different channels to avoid channel interference. However, channels are very rare resources for a WLAN. There are a small number of non-overlapping channels for APs. For example, there are only three non-overlapping channels for the 2.4GHz network. Therefore, the key to wireless applications is how to allocate channels for APs intelligently.

Meanwhile, there are many possible interference sources that can affect the normal operation of APs in a WLAN, such as rogue APs, radars and microwave ovens. The intelligent channel switching technique can ensure the allocation of an optimal channel to each AP, thereby minimizing adjacent channel interference. Besides, the real-time interference detection function can help keep APs away from interference sources such as radars and microwave ovens.

Intelligent AP Load Sharing

According to IEEE 802.11, wireless clients control wireless roaming in WLANs. Usually, a wireless client chooses an AP based on the Received Signal Strength Indication (RSSI). Therefore, many clients may choose the same AP with a high RSSI. As these clients share the same wireless medium, the throughput of each client is reduced greatly.

The intelligent AP load sharing function can analyze the locations of wireless clients in real time, dynamically determine which APs at the current location can share load with one another, and implement load sharing among these APs. In addition to load sharing based on the number of online sessions, the system also supports load sharing based on the traffic of online wireless users.

Layer 7 Wireless Intrusion Detection and Prevention Systems (wIDS / wIPS)

The WX3500H series AC supports the blacklist, whitelist, rogue device defense, bad packet detection, illegal user removal, upgradeable Signature MAC layer attack detection (DoS attack, Flood attack or man-in-the-middle attack) and counter measures.

With the built-in knowledge base in WX3500H, you can perform timely and accurate wireless security decisions. For determined attack sources such as rogue AP or terminals, you can perform visible physical location monitoring and switch physical port removing.

With H3C firewall/IPS device, network infrastructure can also implement layer 7 security defense in wireless campus, covering wired (802.11) and wireless (802.3) secure connections on an end-to-end basis.
