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. An egress policing processor is included at each output port on broadband switches to police the traffic on each virtual path link which contains one customer's multiplexed virtual channel connection traffic.
