TL;DR: In this paper, Service Capability Interaction Manager (SCIM)-type functionality is provided at a horizontal service layer in an Service Oriented Architecture (SOA)-based approach.
Abstract: Service Capability Interaction Manager (SCIM)-type functionality is provided at a horizontal service layer in an Service Oriented Architecture (SOA)-based approach. SCIM composition is provided at multiple levels, including the level of composition where servlets have full access to the context information of the service layer. SCIM composition also occurs at the level of an application dispatching messages to multiple applications/services for processing the messages. The functionality at the service layer also can be programmed using policies, such that routing decisions can be made dynamically as the result of processing conditions and actions. An incoming message can result in a Web service being triggered that in turn triggers a BPEL or SOA workflow, the workflow calling multiple operations to process the message as a result of a routing table or header, environmental and contextual information at the service level, and other information such as user preference or presence information.

TL;DR: This paper provides the first study of the managerial issues related to the design and provisioning of incentive-compatible caching services and finds that declining bandwidth costs will put negative pressure on cache operator profits, unless consumer adoption of broadband connectivity and the availability of multimedia content provide the necessary increase in traffic volume for the caches.
Abstract: Network caches are the storage centers in the supply chain for content delivery-the digital equivalent of warehouses. Operated by access networks and other operators, they provide benefits to content publishers in the forms of bandwidth cost reduction, response time improvement, and handling of flash crowds. Yet, caching has not been fully embraced by publishers, because its use can interfere with site personalization strategies and/or collection of visitor information for business intelligence purposes. While recent work has focused on technological solutions to these issues, this paper provides the first study of the managerial issues related to the design and provisioning of incentive-compatible caching services. Starting with a single class of caching service, we find conditions under which the profit-maximizing cache operator should offer the service for free. This occurs when the access networks' bandwidth costs are high and a large fraction of content publishers value personalization and business intelligence. Some publishers will still opt out of the service, i.e., cache bust, as observed in practice. We next derive the conditions under which the profit-maximizing cache operator should provision two vertically differentiated service classes, namely, premium and best effort. Interestingly, caching service differentiation is different from traditional vertical differentiation models, in that the premium and best-effort market segments do not abut. Thus, optimal prices for the two service classes can be set independently and cannibalization does not occur. It is possible for the cache operator to continue to offer the best-effort service for free while charging for the premium service. Furthermore, consumers are better off because more content is cached and delivered faster to them. Finally, we find that declining bandwidth costs will put negative pressure on cache operator profits, unless consumer adoption of broadband connectivity and the availability of multimedia content provide the necessary increase in traffic volume for the caches.

TL;DR: In this article, a label switch path is managed by comparing at least one packet field value included in a packet of data to mapping field values of a mapping that correlates the mapping fields values with queues.
Abstract: Differentiated service classes on a label switch path are managed by comparing at least one packet field value included in a packet of data to mapping field values of a mapping that correlates the mapping field values with queues. The packet is stored into one of the queues based on the comparing. A first subset of the queues is scheduled using a first queue scheduling algorithm and a second subset of the queues is scheduled using a second queue scheduling algorithm. The packet is transmitted onto the label switch path in accordance with a predefined scheduling order of the first subset of the queues and the second subset of the queues.

TL;DR: A descriptive structure for the analysis of this complexity which combines graph theory and network flows with economic tools is offered and can be used to analyze service systems in terms of the value they deliver, how they deliver it, and how value can be discovered and increased.
Abstract: The economic structure of service systems has steadily increased in complexity in recent years. This is due not only to specialization in direct material production and services offered, but also in the ownership and management of resources, the role of intangible assets such as process knowledge, and the context in which goods and services are consumed. This increase in complexity represents both a challenge and an opportunity in a service-oriented economy. In this paper, we offer a descriptive structure for the analysis of this complexity which combines graph theory and network flows with economic tools. Our analysis is based on publicly observable information and can be used to analyze service systems in terms of the value they deliver, how they deliver it, and how value can be discovered and increased. We show how this analysis can be applied (in the example of a car manufacturer and its service system for suppliers and dealerships) to improve customer satisfaction and provide options and analysis models for outsourcing decision makers.

TL;DR: In this article, a system is described that provides functionality for mobile communications service bridging with distributed service gateway call managers that allow application clients running on users' communication devices to be served by any of the available service gateways, preferably in an active active load balance configuration.
Abstract: A system is disclosed that provides functionality for mobile communications service bridging with distributed service gateway call managers that allow application clients running on users' communication devices to be served by any of the available service gateways, preferably in an active-active load balance configuration. Each service gateway instance may bridge the application client to a range of network services such as voice origination and termination services, IM services, messaging services, online community services, IP voice services, and premium services such as multiparty click-to-conference, directory services, and voice mail.
