<p>A virtual dial-up service is provided via multiple Internet Service Provides (ISPs). In particular, a remote user accesses the virtual dial-up service by establishing a connection to a serving ISP. The Serving ISP establishes a first tunnel to an anchor ISP. The latter establishes a tunnel to, e.g., a private intranet. As a result, a virtual private network (VPN) service is provided that enables remote access, via multiple tunnels, to a private network. <IMAGE></p> |
