Abstract

See full text

An approach provides a communication network that supports one or more network-based Virtual Private Networks (VPNs) to resist Denial of Service (DoS) attacks. A first boundary router is configured to provide a Virtual Private Network (VPN) that supports quality of service levels, and interfaces an access network via a Customer Premise Equipment (CPE) edge router and a physical access link. A second boundary router is coupled to a public network. The access network connects to the first boundary router, and wherein the first boundary router and the second boundary router are connected by a separate logical connection to prevent denial of service attacks on the physical access link originating from sources outside the VPN.
