D-Link DSA-3100 Wireless Service Gateway gateways/controller

The DSA-3100 Wireless Service Gateway is a Network Access Control System (NACS) that manages intelligent AAA (authentication, authorization and accounting) for all wire and wireless network users. This security device coordinates ISO Layer 2, 3, 4 operations to provide your network with comprehensive functions, including IP plug and play, station isolation, traffic management and accounting, and network policy enforcement.

Network Access Security
The DSA-3100 Wireless Service Gateway provides you a comfortable and secure way to provide entrusted computers access to your LAN/WAN. The system guarantees that only registered users are able to use network resources.

AAA Function Execution
The DSA-3100 performs for you authentication, authorization and accounting (AAA), three basic issues that are encountered frequently in many network services. Examples of these services are dial in access to Internet, electronic commerce, Internet printing, and Mobile IP. Authentication acts to verify an identity so authorization can be granted to access a resource. Accounting collects resource consumption data for the purposes of trend analysis, and capacity planning, billing, auditing, and cost allocation.

Can Be Used on Commercial Network
The DSA-3100 can also be installed in a commercial network providing services to public. Authentication is needed to make sure that the user of the service is who he claims to be. This is quite important, because you don't want someone else using the service you have paid for. After the user has been authenticated we need a way to ensure that the user is authorized to do the things he is requesting. For example, if you are a normal user you don't have the permissions to access all the files in a file system. Usually authorization is provided by using access control lists or policies. Accounting collects information of the network usage for billing, capacity planning and other purposes.
