Abstract
A system and method for operating a Broadband ISDN to support a viable virtual private network (VPN) service are attained by establishing a plurality of virtual path links connecting customer locations and broadband switching systems, by cross-connecting virtual channel links at the broadband switching systems to establish end-to-end virtual channel connections, and by policing both the input and output traffic only on the virtual path links. The egress policing function is attained through the use of the ingress policing processors by looping back one customer's traffic from an outgoing trunk into an input port on the broadband switching system.
