PolyViNE: policy-based virtual network embedding across multiple domains

In this paper, we present PolyViNE, a policy-based inter-domain VN embedding framework that embeds end-to-end VNs in a decentralized manner. PolyViNE introduces a distributed protocol that coordinates the VN embedding process across participating InPs and ensures competitive prices for service providers (SPs), i.e., VN owners, while providing monetary incentives for InPs to participate in the process even under heavy competition. We also present a location-aware VN request forwarding mechanism -- based on a hierarchical addressing scheme (COST) and a location awareness protocol (LAP) ? to allow faster embedding and outline scalability and performance characteristics of PolyViNE through quantitative and qualitative evaluations.
