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.
