Fee-based message delivery system

Abstract: The present invention relates to a system and method for fee-based messaging over a global communication network. A method is disclosed wherein a prospective recipient of messages establishes prices for a variety of services and for various tiers of senders. Generally, all messages to a recipient pass to a service provider which informs the sender of the price for a set of possible services, one example of which is the reading of an email text message. The sender then generally pays the price corresponding to the service requested, and the message is transmitted to the recipient.

Service engineering to intensify service contents in product life cycles

Abstract: This paper discusses how to establish service engineering that is intended to intensify service contents of product life cycles. Intensification of service and knowledge contents within product life cycles is considered crucial for dematerialization, in particular, to design optimal product-service systems from the viewpoint of environmentally conscious design and manufacturing in advanced post industrial societies. The paper tries to define service as an activity that changes the state of a service receiver. Service contents of the service is provided by a service provider and delivered through a service channel. Artifacts are either the service contents or the service channel. Service engineering looks at development, design, and production of services and aims at improving the efficiency and quality of the service as well as its delivery. To establish service engineering, the paper then proposes a modeling technique of service.

A Scalable Algorithm for the Placement of Service Function Chains

Abstract: Network function virtualization (NFV) decouples software implementations of network functions from their hosts (or hardware). NFV exposes a new set of entities, the virtualized network functions (VNFs). The VNFs can be chained with other VNFs and physical network functions to realize network services. This flexibility introduced by NFV allows service providers to respond in an agile manner to variable service demands and changing business goals. In this context, the efficient establishment of service chains and their placement becomes essential to reduce capital and operational expenses and gain in service agility. This paper addresses the placement aspect of these service chains by finding the best locations and hosts for the VNFs and to steer traffic across these functions while respecting user requirements and maximizing provider revenue. We propose a novel eigendecomposition-based approach for the placement of virtual and physical network function chains in networks and cloud environments. A heuristic based on a custom greedy algorithm is also presented to compare performance and assess the capability of the eigendecomposition approach. The performance of both algorithms is compared to a multi-stage-based method from the state of the art that also addresses the chaining of network services. Performance evaluation results show that our matrix-based method, eigendecomposition of adjacency matrices, has reduced complexity and convergence times that essentially depend only on the physical graph sizes. Our proposal also outperforms the related work in provider’s revenue and acceptance rate.

Software and hardware for publishing and viewing products and services for sale

Abstract: A computer system that utilizes client/server software to allow users of the client software to log into a server and publish information about a product or service. Once the information is published, other users of the client software may log into the server to browse or search for the information. This system is designed to help extractors and manufacturers of products, as well as service providers, to advertise their product or service to other extractors, manufacturers, service providers, distributors, retailers or other consumers to help aid in the distribution of those products or services. The system is also designed to help reach these establishments over a wide area, limited only by communication networks, and the system is kept current through the use of the established users of the client allowing rapid change.

PolyViNE: policy-based virtual network embedding across multiple domains

Abstract: Intra-domain virtual network embedding is a well-studied problem in the network virtualization literature. For most practical purposes, however, virtual networks (VNs) must be provisioned across heterogeneous administrative domains managed by multiple infrastructure providers (InPs). 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 – basd on a hierarchical addressing scheme (COST) and a location awareness protocol (LAP) – to allow faster embedding. We outline scalability and performance characteristics of PolyViNE through quantitative and qualitative evaluations.
