Fault tolerance schemes can be used to increase the availability and reliability of network services. One aspect of such schemes is service failover — the reconfiguration of available resources and restoration of state required to continue providing the service despite the loss of some of the resources and corruption of parts of the state. We have previously presented CoRAL, a fault tolerance s...

AbstrAct: Muti-objective optimization deals with the simultaneous optimization of two or more conflicting objective functions in real-life systems. This paper deals with the multi-objective optimization in service systems. The goal of service systems is to provide cost-efficient service to customers, while at the same time, reducing the customer waiting time for service. In general, a low cost ...

Service composition is emerging as an important paradigm for constructing distributed applications by combining and reusing independently developed component services. One key issue of service composition is how to identify relevant service operations so as to compose services rapidly and correctly. A promising approach to simplifying the search of relevant service operations in service composi...

The most straightforward but also most inflexible configuration approach for invocation of remote services is to hard wire the location, interface, behavior and other properties of remote services into the local application. Loosely coupled decentralized systems call for solutions that are more flexible and can seamlessly adapt to changing conditions. While advances have recently been made in t...

Operators are adopting end-to-end Service Delivery Platforms (SDPs) to increase service revenue growth and retain customers. They require these additional SDP enablers to achieve efficient service lifecycle management. Rapid rollout, operation and retirement of services are necessary to optimise service revenues. Historical operator experiences clearly highlight the significant risks associated...

Small and medium-sized enterprises public service platform(SMEPSP for short in the following paper) is a comprehensive service platform to provide services such as technology innovation, financing guarantee, business supporting and management consulting to small and medium-sized enterprise(SME for short in the following paper). This article is based on questionnaire surveys and interviews to th...

This paper describes basic concepts of information technology service management and its association with theory of normatively regulated activities. Normatively regulated activities are characterized by precise objective or purpose, participation of actors as role-holders, and norms and rules that govern the performance of these activities. At the same time primary objective of service managem...

This document specifies an automatic tunneling mechanism tailored to advance deployment of IPv6 to end users via a service provider’s IPv4 network infrastructure. Key aspects include automatic IPv6 prefix delegation to sites, stateless operation, simple provisioning, and service, which is equivalent to native IPv6 at the sites that are served by the mechanism.

In der Literatur zur ServiceOrientierten Architektur (SOA) wird der Begriff des Service häufig synonym zu den in der Softwaretechnik etablierten Begriffen Komponente, Schnittstelle und Operation verwendet. In dem Artikel wird eine alternative Definition vorgestellt, welche den Service in den Kontext der Geschäftsarchitektur eines Unternehmens stellt. Zusammenhänge zu den in der Softwaretechnik ...

Under deregulation, the competition for air general cargo business between all-cargo airlines and combination airlines is foreseeable. This paper proposes a model structure that analyzes the pricing and service strategies between two kinds of carriers within a competitive framework, and evaluates airline profits based on game theory and a microeconomic theory of airline behavior. The model is a...
