A network that supports VPNs is enhanced to allow users in one VPN to communicate with users in another VPN in the course of executing a predefined application, such as VoIP. This capability is achieved dynamically by enabling a device that can communicate with the network elements that operate to normally prohibit inter-VPN communication to direct those network elements to enable such communication, at least for the purposes of specific applications.

Externally controlled reachability in virtual private networks

A method and apparatus for providing traffic management for distributed denial of service (DDOS) traffic. Within a communications network, a DDOS detection system monitors network traffic to identify traffic that is designed to attack a particular server within the network and their entry points into the network. A traffic routing control unit is requested to deny service to the DDOS traffic. By selectively manipulating the routing information propagated to network edge routers, the traffic that is denied service is limited to mostly DDOS traffic and is routed to a cleaning center or a null address in the most effective fashion.
