Open Marketplace and Service Orchestration in Virtual Network Environments

A key challenge in multi-vendor heterogeneous virtual networks is providing transparent access to network resources and virtual functions in a manner that enables users to combine them appropriately into meaningful end-to-end services. In this paper, we present a solution that consists of two components: an open marketplace where vendors and users of network resources and functions meet to establish economic relationships; and a planning service for creating end-to-end communication services from functional building blocks available in the marketplace. We also present optimal yet efficient algorithms for tackling variants of the associated service chain routing problem.
