Inception to application: A GENI based prototype of an open Marketplace for network services

摘要

Choice-based network architecture enables users the power to choose services from a set of network service offerings from multiple providers within a marketplace. To facilitate marketplace alternatives and enable fine-grain service composition, a common service specification should represent a general-extensible design for describing a service. This allows users to discover, negotiate, and purchase network services from service providers using service advertisements in the marketplace. We have successfully developed a ChoiceNet prototype which rectifies some of the shortcomings of the earlier prototypes and demonstrates a contractual agreement between multiple network service providers to realize multiple end-to-end application scenarios using the common service specification within the GENI environment. Our implementation showcases the integration of two contrasting payment models for the procurement of contractual agreements for network services. Successful agreements results in the provisioning of the advertised network services. This demo helps in visualizing the network service life cycle as seen by the Marketplace.
