A ROUTER-BASED SYSTEM FOR PROVIDING MULTI-LEVEL DATA FILTERING AND SECURITY SERVICES IN A BROADBAND ENVIRONMENT

摘要

The present invention relates to a router-based system (50) for providing multi-level data filtering, security services and content related switching services in a broadband environment (13). This system allows the operator of a network, and in particular, a Next Generation Network to provide outsourcing services to its subscribers and ensure performance of such services and Service Level Agreements. These services are executed across multiple layers of the ISO seven-layer model, within or co-operating with Edge Routers (20), at the point of entry to the Internet or network. Services offered by the present invention include security services, selective browsing services and application layer services, which can be used to substantially enhance security, content, management and control in a network.
