A Framework for the establishment of inter-domain, on-demand VPNs
– Virtual Private Networks (VPNs) are a popular and cost-effective means to build wide-area corporate networks, since they provide bandwidth, privacy and security for a fraction of the cost of private networks. However, establishing VPNs across different domains (interdomain VPNs) is still a cumbersome task, requiring humanbased negotiation between involved carriers, manual configuration of network equipment and inefficient exploitation procedures during the whole VPN life cycle. For these reasons, inter-domain VPNs are usually contracted in a long-term basis and thus appropriate only for a limited set of usage scenarios. In this paper we propose a framework for efficient provisioning of inter-domain VPNs, comprising a business layer for inter-carrier negotiation and orchestration, policy-based mechanisms for intra-domain resource management, and RFC 4364-based mechanisms for configuration of VPNs. This framework will allow ISPs to provide much more elastic VPN services, able to supp...
