Multi-Provider Service Negotiation and Contracting in Network Virtualization
Network Virtualization Environment (VNE) affords great business flexibility to the customers and the providers as multiple providers can jointly support a customer's virtual network. Under the current network model, a group of Infrastructure Providers (InPs) peer with each other to provide a packaged deal. Such a business arrangement is not customer-driven, does not promote fair market competition and does not ensure cost minimization. Furthermore, the on-demand nature of virtual networks requires efficient and automated service negotiation and contracting. In this paper, the authors present V-Mart. To the InPs, V-Mart offers an environment to participate in a faithful and fair competition over the VN resources; and to the SPs, it offers a customer-driven virtual resource partitioning and contracting engine.
