D-Link DWS-4026 is D-Link’s next generation Unified Wired/Wireless Gigabit Switch with an array of advanced features and 802.11n support. With the ability to manage up to 64 DWL-8600AP wireless Access Points by itself and up to 256 DWL-8600APs in a Switch Cluster, the D-Link DWS-4026 is a full-featured and cost-effective mobility solution for mid-to large enterprises and service providers. Extremely versatile and flexible, the DWS-4026 can be deployed as a Wireless Controller in the core network or as a L2+ PoE Gigabit Switch at the edge depending on the requirement. By centralising WLAN configuration and management functions, D-Link DWS-4026 enables network administrators to have control, security, redundancy, and reliability needed to scale and manage their wireless networks easily and efficiently.
Comprehensive Wired/Wireless Security
On the wired side, the D-Link DWS-4026 utilises Dynamic ARP Inspection (DAI) and DHCP Snooping to ensure maximum security. Together, DAI and DHCP Snooping will prevent even the most sophisticated attacks such as man-in-the-middle and ARP poisoning. Along with other advanced security features such as 802.1X Access Control, Denial-of-Service Protection, Broadcast Storm Control and Protected Port, the D-Link DWS-4026 provides robust and centralised security, ensuring maximum network reliability.
Wireless clients can enjoy seamless and uninterrupted roaming from AP to AP managed by a D-Link DWS-4026 even if they are not in the same subnet. Because the D-Link DWS-4026 employs various mechanisms such as pre-authentication and key-caching, wireless users can freely “roam” the entire network without needing to re-authenticate. The additional Fast Roaming feature results in disruption-free, reliable wireless connectivity crucial for mobile applications such as Wi-Fi IP Phones and wireless PDAs. Furthermore, the D-Link DWS-4026 supports advanced “AP-AP Tunneling”, which is used to support L3 roaming for wireless clients without forwarding any data traffic to the Unified Switch. This can help to significantly reduce network traffic and save bandwidth.
Voice-Optimised Quality of Service (QoS)
The D-Link DWS-4026 is specifically designed and optimised for Voice over Wireless traffic with features such as Auto-VoIP and Voice VLAN. The Auto-VoIP feature explicitly matches VoIP streams and provides them with a better class-of-service than ordinary traffic.
These VoIP streams include the popular call-control protocols such as SIP, H.323 and SCCP. Voice VLAN enables the switch ports to carry voice traffic with defined priority, ensuring that the sound quality of an IP phone will be safeguarded from deteriorating when data traffic on the port is high. The D-Link DWS-4026’s Voice QoS capability enables administrators to maintain the integrity and priority of the most time-sensitive traffic.
In addition, the D-Link DWS-4026 supports traffic shaping, which helps to smooth out temporary traffic bursts over time so that the transmitted traffic rate is bounded. Other advanced QoS features include per-flow bandwidth control, minimum bandwidth guarantee and 802.1p CoS all help to keep the network traffic in a predictable manner.
