DCWS-6028(R2) Thiết bị điều khiển truy nhập

Overview

The DCWS-6028(R2) is a high-performance smart wireless access controller (AC) for medium wireless networks, which can manage up to 1024 access points (APs). It provides complete RF management and security mechanism, powerful QoS, seamless roaming and complete control of APs, can be used to construct medium-sized network for campus, hotel, enterprise office, hospital, etc.

With hardware ASIC, DCWS-6028(R2) could support line-rate forwarding of IPv4/IPv6 data packets and support dynamic routing protocols such as RIP, OSPF, BGP and PIM, as well as IPv6 RIPng, OSPFv3 and PIM6. It also integrates Ethernet switch function, and provides unified access control for wired and wireless users. It offers 16 GE combo ports, 8 fixed SFP ports, and 4* 10G SFP+ ports.

Key Features and Highlights

Wired-and-wireless Unified and High-Reliability Network

Combination of routing switch and wireless AC

The DCWS-6028(R2) can be used as a routing switch and a wireless access controller simultaneously in a trunk deployment mode, with an ASIC-based forwarding architecture and high-density access-ports, it can provide line-speed forwarding for both wired and wireless traffic.

High-reliability backup mechanism

The DCWS-6028(R2) supports the following high-reliability backup mechanisms to ensure that a wireless network runs reliably:

• N+1 backup
• N+M backup

1+1 modular redundant input power

The DCWS-6028(R2) supports two modular AC input power, which provides 1+1 input power redundancy.

Automatic emergency mechanism of APs

This mechanism enables an AP to intelligently detect a link between AC and AP. When detecting the breakdown of the link the AP quickly switches its operating mode so that it can continue to forward data and allow new users to access the network. This mechanism makes sure that the access is available for all users when the AC is down.

Intelligent Control of Wireless Network

Intelligent RF management

The DCWS-6028(R2) provides an automatic power and channel adjustment function. It employs particular RF detection and management algorithms to attain a better RF coverage effect. When the signals of an AP are interfered with by strong external signals, the AP may automatically switch to an appropriate operating channel under the control of the AC to avoid such interference. It also supports the blackhole compensation mechanism, which adjusts the AP power to cover the blind area resulted by the crashing of some APs

Intelligent control of terminals based on airtime fairness

This function makes sure that both the low-rate and the high-rate clients get relatively the same accessing time, which can avoid the low-rate clients to affect the AP overall performance by taking up too much accessing time.

 Intelligent load balancing mechanism

In general, a wireless client will select an AP according to the signal strength of APs. So, it may happen that one AP connected a large number of APs while the others connected very little, causing the small bandwidth for each client. The DCN load balancing mechanism can overcome this problem by:

• Load balancing between APs based on traffic
• Load balancing between APs based on the number of users
• Load balancing between radios within the AP based on the number of users

Intelligent identification of terminals

The DCWS-6028(R2) can identify a terminal in different ways by combining with DCN smart APs and a unified authentication platform. It can identify the OS of a terminal, such as Apple iOS, Android, and windows, the size of a terminal, and the type of a terminal, such as mobile phone, laptop, and PC. Basing on these identifications, DCWS-6028(R2) can implement dynamic policies for different types of terminal and present a corresponding-sized authentication page.

PEAP user authentication

Protected Extensible Authentication Protocol (PEAP) authentication can provide a better user experience. The user needs to manually enter the username and passwords only during the first-time certification, the second time, and the subsequent certifications are performed automatically.

Secure and Controllable Wireless Network

User isolation policy

The DCWS-6028(R2) supports the isolation of wireless users. If this user isolation function is enabled, only the communication between the clients and gateway is allowed, the direct communication between clients is forbidden, which can increase the security of the wireless network.

Wireless intrusion detection and intrusion defense

The DCWS-6028(R2) supports wireless intrusion detection and intrusion defense features, such as detection of unauthorized wireless devices, intrusion detection, blacklist, and white list, as well as anti-DoS for various wireless management packets, thereby greatly improving security management of an entire wireless network.

Secure user admission

The DCWS-6028(R2) provides multiple secure access, authentication, and accounting mechanisms for various application environments. These mechanisms include:

• 802.1x authentication
• Captive portal authentication, including built-in portal, and custom portal authentication modes
• MAC address authentication
• LDAP authentication
• WAPI encryption and authentication
• Wired/wireless integrated authentication and accounting

Easy-to-Manage Wireless Network

AP plug-and-play

When used with the DCWS-6028(R2), DCN smart APs support plug-and-play and zero configuration. DCWS-6028(R2) undertakes all the management, control, and configuration of the APS. Network administrators do not need to separately manage or maintain a huge number of wireless APs.

Remote probe analysis

The DCWS-6028(R2) supports remote probe analysis of APs. It enables the APs to captures Wi-Fi packets and mirrors them to a local analysis device in real-time to help network administrators troubleshooting or optimizing the network. The remote probe analysis function can perform analysis of a single working channel continuously or all channels in a polling mode to flexibly meet various wireless network monitoring requirements. 

Typical Applications
