Portal/web based authentication is proposed as access control method. A typical portal system consists of four basic components including authentication client (portal client), portal server, broadband remote access server (BRAS) and authentication/authorization/accounting (AAA) server. i). Portal client: Client system that triggers authentication requests on a portal network. It can be a browser using the Hypertext Transfer Protocol (HTTP). ii). Portal server: Server system that listens to authentication requests from portal clients and exchanges client identity information with the BRAS. It provides free portal services and a web-based authentication interface. iii). BRAS: Broadband remote access server, used to redirect HTTP requests to the portal server, and cooperate with the portal server and AAA server to implement authentication/authorization/accounting for users. iv). AAA server: Authentication/authorization/accounting server, used to cooperate with the BRAS to perform authentication/authorization/accounting for users. 1.10.3. Following is the call flow: i). When an unauthenticated user enters a website address in the address bar of the IE to access the Internet, an HTTP request is created and sent to the BRAS, which redirects the HTTP request to the web authentication homepage of the portal server. ii). On the authentication homepage/authentication dialog box, the user enters and submits the authentication information, which the portal server then transfers to the BRAS. iii). Upon receipt of the authentication information, the BRAS communicates with the AAA server for authentication and accounting. iv). After successful authentication, the BRAS opens a path for the user to access the Internet. 1.10.4. The bidder shall provide details of offered billing system, its implementation and integration with PTCL billing and AAA systems.
