Abstract
The emergence of an open market for telecommunication services provides a wide range of opportunities for the provision of value added services by providers other than public network operators. One service already available today is that of a Virtual Private Network (VPN) that provides dispersed corporate sites with wide area data communication capabilities using public network services. The introduction of Broadband ISDN allows for the provision of VPN services in a more integrated fashion than currently. However any effective VPN service must be able to deal with the technological and organizational heterogeneities that are present when providing a high level of service functionality over an arbitrary number of administrative and technological domains. This paper presents a management service for a VPN service that addresses some multi-domain and network heterogeneity issues. It outlines how a design based on the ITU-T's Telecommunications Management Network (TMN) Recommendation was developed and how working prototypes were implemented over real broadband networks.
