“…To the best of our knowledge, other approaches such as the X-Bone [30], Genesis [6] and Supranet [13] are more focused on providing an overall service architecture and have not fully developed techniques for enabling per-VPN QoS. Earlier research in VPNs, such as in [7,15,24] focused on VPN services on broadband ATM networks, i.e., they developed methods for managing and mapping VPNs on virtual circuits. While some measure of QoS is attainable through dedicated virtual circuits, these ATM-based solutions typically do not allow bandwidth sharing across VPNs, since VPN¯ows are mapped directly to virtual circuits.…”

“…Virtualization of the link bandwidth provides each VPN with virtual links of guaranteed capacity, and the autonomy to specify its own bandwidth sharing policy. Earlier work in VPN services such as in [7,15,24,31] did not consider statistical sharing of under-utilized resources. In this work, the additional performance bene®t of statistical multiplexing is achieved without compromising any bandwidth guarantees by using the fair service curve (H-FSC) [27] hierarchical packet scheduler.…”

In this paper, we propose and implement Virtual Network Service (VNS), a value-added network service for deploying virtual private networks (VPNs) in a managed wide-area IP network. The key feature of VNS is its capability of providing a customer with a VPN that is customizable with management capabilities and performance properties comparable to a dedicated physical network. In addition, VNS ensures con®dentiality of data and principals through the use of IPSEC. The main technique underlying VNS is the virtualization of routers in both control and data planes. Virtualization of the control plane enables customizable routing and signaling per VPN. On the data plane, packet forwarding and link bandwidth are virtualized. Virtualization of the forwarding mechanism on the data plane enables forwarding of trac according to each VPN's topology and policies. Virtualization of the link bandwidth enables each VPN to have guaranteed quality of service (QoS) and customized resource management policies. We have developed a VNS prototype for deployment on the CAIRN network. The VNS prototype implements several resource management mechanisms including packet scheduling, signaling and runtime monitoring. A graphical user interface enables service providers to manage, con®gure and deploy VPNs remotely. Ó

“…[OHT92]) can be used to exploit multiplexing among calls with the same source-destination pairs. Finally, the techniques described in [FOT95] and [CHA96a] can be used to multiplex calls with different source-destination pairs. Depending on the type of VPN service the provider offers, the customer can choose to implement one or more of the above multiplexing schemes in the customer control system.…”

“…Specifically, public VPN services based on Constant Bit Rate (CBR) Virtual Paths (VPs) can be provided efficiently today [ATS93,FOT95]. However, such a service requires resource control by the customers, since they will be billed based on allocated bandwidth--even if they do not use it.…”

We present an architecture for customer management and control of a broadband VPN service. The architecture is aimed at giving the VPN customer a high level of control over the traffic on the VPN, such that end-to-end requirements for the customer's enterprise network can be met. We describe how different control and management objectives can be achieved with this architecture. Its design includes a generic resource controller, which can be specialized in order to realize a large class of control schemes, following a customer's specific requirements. We have implemented a prototype of this architecture on a high-performance emulation platform. The prototype allows us to validate the management and control functionality of the customer control system and to demonstrate the performance characteristics of different realizations of the architecture.

Inter-domain service management of broadband virtual private networks

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 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. 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.
