Summary:A network architecture and service platform for providing virtual private network ("VPN") over an ATM network (110). The architecture provides service s for voice, video and data traffic among multiple VPN customers over a shared ATM network by implementing intelligent control devices (150a) to perform enhanced processing of ATM call set-up messages, including validations and routing translations. Hierarchical routing mechanism provided by ATM, along with customized customer addressing schemes, are used to overlay customer VP Ns (115a) as higher-level networks onto the shared ATM network. The control devices translate customer ATM VPN address to internal ATM network addresses . The ATM switch (120a) network then performs lower-level network processing, using internal network addressing to set-up a virtual connection for a VPN call. The intelligent control devices may also explicitly state the end-to-e nd route.
