Unified Wired/Wireless Switching
Overview
The D-Link® Unified Wired/Wireless Switching solution
provides an innovative evolution in wireless LAN.
Complex installations, intricate management utilities
and limited scalability had previously made network
administrators hesitant to deploy facility-wide wireless
LAN. Now, D-Link Unified Wired/Wireless Switching
architecture simplifies installation. In addition, access
security, wireless throughput and network convergence
is significantly enhanced. Benefactors of this Wi-Fi®
innovation include IT integrators, network administrators,
business end-users, government organizations, schools,
hospitals, and hotspots such as convention halls, hotels
and airports.
Scalable and Flexible Wireless Deployment
The centerpiece of D-Link Unified Wired/Wireless
Switching lies in a scalable and flexible architecture.
The Unified Switch can be easily added to the customer’s
existing network infrastructure and centrally manage
the Access Points. Overlay Deployment protects
the customer’s investment on the wired network,
while providing wireless LAN capability to the entire
organization. Furthermore, the Unified Switch can be
deployed at the network edge as a wireless controller
and an L2 edge switch. This type of edge deployment is
beneficial for customers looking to replace their current
switches with a more robust and full-featured product.
The D-Link Unified Switch is designed for medium-sized
to large wireless networks. This affordable solution
provides flexibility and investment protection through
scalable expansion and unified LAN/ WLAN deployment
and easy upgrades for future technologies through
Gigabit connectivity.
Adaptable Wireless Technology
The Unified Switch’s flexible architecture not only
includes physical deployment, but also offers effective
wireless traffic management capability. Data from the
clients can be configured to tunnel back to the Unified
Switch before reaching its destination. This approach
allows for a coordinated network control and centralized
security policy enforcement. Alternatively, Access Points
can handle and forward wireless traffic ideally without
having to go through the Unified Switch. This nontunnel mode is especially practical in remote offices or
applications that require high performance and optimized
traffic flows. The flexibility offered by D-Link Adaptable
Wireless technology empowers any organization to
enjoy the benefits of a wireless network.
Centralized Policy Control
Profile configuration is applied to a wireless access point
when it is deployed or when it is reset. Profiles dispatched
from the switch to the AP include RADIUS server settings,
radio configuration, SSID, VLAN, tunnel settings, and
QoS configuration. Configuration is simplified because
the administrator does not have to make individual
settings for each AP. This enhances security because the
configuration is not saved within the AP, hence it cannot
be retrieved when an AP is dismounted or stolen.

Enhanced and Resilient Security
The D-Link Unified Switch provides the highest levels of
security for both voice and data, with support for MAC
Authentication, Captive Portal, and industry standard
personal/enterprise WPA/WPA2 security. WPA2 utilizes
the Advanced Encryption Standard (AES), which is
considered to be the most robust and secure encryption
algorithm. The Unified Switch also provides means
to define and detect Rogue APs, preventing illegal
intrusions into the internal network. Security can be
pre-set and RF channels auto-adjusted for each AP, so
when an AP is added or removed, the entire network does
not have to be reconfigured. The switch will automatically
configure the new AP with the same configuration as the
previous units.
Dual Band Wireless Access Point
The DWL-8500AP operates on simultaneous dual 2.4GHz
and 5GHz frequency bands. This system provides
automatic adjustment of 802.11a/b/g RF channels,
multiple SSID for each frequency band, and optimal
transmit power to provide mobile users with high quality,
secure wireless signals.
Uninterrupted Wireless Connectivity
The system maintains a centralized database of wireless
user’s access information such as their MAC addresses
and authentication keys. As wireless users roam around
the office using wireless equipment, they may change
their connection from AP to AP. By constantly monitoring
the AP status, the switch can establish AP-to-AP roaming
for these users without requiring them to re-establish
authentication keys. This fast roaming process results in
disruption-free, reliable wireless connectivity crucial for
mobile applications such as Wi-Fi® IP phone and wireless
PDA connection. In addition to updating information of
APs managed by the same switch, the system also
supports AP information updates across multiple
peer switches. As a wireless user moves from one AP
affiliated to a switch to another AP connected to another
switch, inter-switch roaming is instantly performed
across the peer switches to produce a smooth, fast
wireless connection in a multi-departmental enterprise
environment.
Unified AP
The DWL-8500AP can be configured either as managed
or standalone APs. In managed mode, the switch
automatically discovers and centrally manages the APs.
Furthermore, all the configuration files and security
settings are pushed to the APs, significantly reducing IT
overhead as the WLAN network scales up. With WLAN,
users have the mobility to move around the network;
therefore the authentication and user tracking are
executed on the Unified Switch with a consolidated and
secure wireless system. They can also act as standalone
APs depending on the application or network condition.
Captive Portal
Apart from the wireless encryption standards, the Unified
Switch offers an addition level of security called “Captive
Portal”. Captive Portal is a web-based authentication
process in which the wireless clients request for access
through the web browser. The AP or switch port captures
HTTP/HTTPS traffic and then re-directs the client to an
authentication portal. Once the username and password
of the client has been authenticated by either the switch
or the RADIUS server, access is granted. Captive Portal
is SSID-based and supports fast roaming, making it an
ideal security solution.
Automatic Channel and Power Adjustment
Normally, when adding APs to the network, system
administrators select the unoccupied or least used RF
channels to avoid interference with other AP and RF
devices. They also set transmitter output power at a
level, strong enough for RF signals to reach wireless
clients, but weak enough to minimize interference with
other devices’ RF signals. To simplify this process and
optimize RF usage, the switch automatically adjusts the
RF channels and transmitter output power of the entire
system every time an AP is added to or removed from the
network. This automatic adjustment can be programmed
to take effect at a certain time or at specified intervals,
minimizing the need for network administrator to
manually intervene.

Unified Wired/Wireless Switching
Self-Healing and Load Balancing
D-Link DWS series switches offer Self-healing process
and an AP load balancing features to increase the
resiliency of a wireless network. To make up for a sudden
RF signal vacuum created by any “dead” AP (AP with DC
power failure), the switch automatically increases the
transmitter output power of all the neighboring APs to
expand their RF coverage, thereby “healing” the network
“wound”. “Self-healing” can also be accomplished with a
redundant switch, which can take over the management
of the AP if and when the AP loses connection with the
first switch. To ensure continuous connection for current
clients, the switch performs load balancing across the
access points when network traffic reaches a certain
threshold, while rejecting new client-to-AP associations
to avoid bandwidth overcrowding.
Unified Switch Architecture
In addition to being the core unit of the wireless switching
system, the DWS-3024 switch can also function as an
advanced wired device. Features such as IP routing,
ACL, QoS, security features, and Gigabit/10-Gigabit fiber
support, allow businesses to integrate their enterprise
wireless networks with the wired network infrastructure.
The DWS-3024 Unified Switch can be used to upgrade
their current 10/100Mbps desktop connections to Gigabit
capability. Seamlessly upgrade to an 802.11n AP with
Gigabit connections in the future. The advantages
include flexibility to act as wireless controllers or
dedicated full-featured multi-layer LAN switches, or as
dual-role devices.
Medium to Large Business Application
Capable of handling up to 48 access points, D-Link
Unified Wired/Wireless Switching is suitable for
deployment in either a medium or large network
supporting VoIP and numerous mobile wireless
applications. A network site can begin with one switch
to manage a few APs or to use for mixed wired/wireless
LAN purposes. When the number of APs is augmented,
up to four switches in a peer-to-peer configuration
can be added to form a large centralized management
system capable of handling up to 192 access points in
one roaming group.
Network Visualization and Management
By entering the IP address of a managed switch or
into the Internet browser, administrators can view the
topological map and identify the locations of the AP and
the switch. The map displays AP icons and colors used to
differentiate between the different RF channels used by
the AP. Administrators can create individual user profiles
and be informed of any rogue APs. Users’ authentication
is based on profiles and not on any specific access point.
As users move around within a network, their movement
can be traced as they roam from one access point to
another.
