Service Providers often struggle with fluctuating demand of service requests which can lead to prolonged waiting times and hence to dissatisfaction of customers. Therefore, service providers strive for volume flexibility to cope with this challenge. In manufacturing context, a shift of excess demand to an external partner is already common practice while service providers reacted reluctantly to...

the author in this research has tried to link the alexander pattern language theory, which is based on human oriented and spatial factors, to landscape design, which could come to a cyclic model of “a pattern language for landscape design” in iranian schools of architecture. so, a landscape design process based on the value of human-oriented approach, which is extracted from other values, and t...

The SOA Innovation Lab has investigated the use of standard software packages in a service-oriented context. As a result, we present a holistic approach for developing a service-oriented enterprise architecture with custom and standard software packages. It starts on enterprise level with the identification of domains where both the SOA paradigm and standard software are of relevance. Here SOA ...

The high competition among network providers places a demand for new ways to design network services with near zero development time, low cost, and high degrees of customization and evolution. Customization allows to fit the service according to the customers’ requirements, while evolution allows to adapt the service as soon as these requirements change. Moreover, customers are demanding the ab...

Recent peer-to-peer architectures do not fulfill the idea of a service-oriented architecture to allow the flexible composition of services towards concrete applications. This can be justified by the absence of flexible notations for the composition of services that incorporate the dynamic nature exposed by peer-to-peer architectures. In this work, the peer-to-peer architecture DeEvolve is prese...

For quite a long time already, great importance has been attached to the concept of Service-Oriented Architectures for future IT-architectures. However, a major challenge in implementing this concept lies in the gap between the functional department and IT department. Mashups, an architecture also based on services, try to avoid this gap by letting the user himself integrate the services. The f...

An emergent domain that raises some unique engineering challenges is that of software architectures to convert large bodies of unstructured data to human-usable knowledge, such as in the domain of socio-cultural information analysis. We report on an architecture based on Service-Oriented Architectures that we are applying in this domain. We list the requirements that such an architecture must s...

Anycast is a new IPv6 feature that supports service–oriented address assignments in IPv6 networks. However, because there are no protocol standards or even consensus on routing protocols, inter–segment anycast communications are not yet available. In this paper, we first discuss problems and solutions on inter–segment anycast communications. Based on our findings, we propose two routing protoco...

The material presented in this paper is focused on the characteristics of open computational systems and, in particular, the issue of coordinating behavior in such systems, i.e. systemic coordination. Firstly, we introduce a conceptual framework for characterizing systemic coordination at different levels abstraction. Secondly, challenges and opportunities of this framework is outlined as a mat...
