Interest in network functions virtualization (NFV) continues to grow due to its perceived benefits to both service providers and users. One of the main challenges in realizing NFV has to do with orchestration of virtual functions deployed in various locations across the network. In this work, we consider the service-concatenation routing problem, where the objective is to construct a path of minimum...
Network service composition provided as a service in an Open Marketplace enables users to obtain customized end-to-end composed service(s) using the services advertised by the providers in the marketplace. By providing a semantic language for advertising services and offering choice for the composed service(s) we provide a level playing field for the providers and alternatives for the users to choose...
Choice-based future Internet architectures, in which choice is offered for fine-grained network services to different traffic flows, have been proposed in the literature. Such choice-based architectures have been envisioned in literature as realizing an economy of networking services that can give rise to a beneficial ecosystem of providers and consumers over time. Such an architecture would use an...
Open marketplaces of path services are the next step towards realizing “routing-as-a-service.” Such marketplaces will enable users to select from a set of path services offered by multiple competing network providers so as to construct customized end-to-end paths for their applications. This is analogous to online travel marketplaces that allow users to explore travel options and book their travel...
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...
Deployment of innovative new networking services requires support by network providers. Since economic motivation plays an important role for network providers, it is critical that a network architecture intrinsically considers economic relationships. We present the design of a protocol that associates access to network services with economic contracts. We show how this protocol can be realized in...
