D-Link�, the industry leader in innovative networking solutions, introduces another breakthrough in the Airspot family of service gateway products. As the need for on-demand Internet connectivity continues to grow, the D-Link Airspot DSA-5100 Public/Private Hot Spot Gateway provides large establishments a solid solution for adding multiple public access networks while still maintaining the integrity of an existing private network.

The DSA-5100 Hot Spot Gateway is a business-class service gateway designed to segment public and private network infrastructures. By adding a managed switch to the integrated public port, network administrators can deploy several public networks over a large-scale establishment such as a university campus or resort. Through the private port on the DSA-5100, the backend private network such as the campus operation centers or central office, can remain completely separate and secure.

To optimize and maintain network up time and performance, the DSA-5100 Hot Spot Gateway has two built-in WAN ports that support link fail-over in order to provide Internet connection redundancy. In the case that the first ISP''s connection fails, the second link (if configured and conencted to a second ISP) will take over to ensure that Hot Spot customers with maintain uninterrrupted Internet access. The DSA-5100 supports virtually all WAN connection types including static, dynamic, and PPPoE Client.

The DSA-5100 Hot Spot Gateway also offers several advanced features to help manage and support up to 400 public users online at any time. Additional user management controls include bandwidth control, network policy enforcement, customizable user timer, login/logout web-page, online traffic monitoring, and URL redirection.

To ensure authorized network access, the DSA-5100 supports multiple authentication methods such as POP3, RADIUS, LDAP, internal user database, and external Web (HTTP or HTTPS) authentication. With support for 802.1q VLAN tagging, different authentication policies can be used per administrator-assigned VLAN networks for maximum security. In addition, VLAN tagging helps to segment and prioritize incoming traffic. For the private network, the integrated DHCP server and firewall with Denial of Service (DoS) Protection safeguards the network from malicious attacks and hackers.

Network administrators can manage the DSA-5100 Hot Spot Gateway and all of its features via the Web-based, CLI, SSH, or SNMP v2 management interfaces. With a wide array of convenient management utilities, the D-Link Airspot DSA-5100 Public/Private Service Gateway is an efficient and powerful hotspot solution.
