Abstract: The patent describes a flexible, scalable hardware and software platform designed to enable service providers to easily deliver internet, virtual private network (VPN), and firewall services to multiple customers. A key aspect involves a method and system for security services, which includes connecting a plurality of processors in a ring configuration within a first processing system. A secure connection is established between these processors and a second processing system across an Internet Protocol (IP) connection, forming a tunnel. This setup provides both router and host services for a customer, leveraging the processors in the ring configuration and the second processing system. Furthermore, a secure communications tunnel is formed by routing all packets for the tunnel through an encrypting router at the sending end to obtain encrypted packets, which are then routed through a decrypting router at the receiving end of an IP connection.
