The more learner information is shared across a wide range of heterogeneous applications and tools, the more learner profiles will be relevant, reusable and useful for many systems and environments. This proposal stands on a widely used management standard, and introduces an open and generic learner profile supported by a service-oriented architecture ensuring exchange and reuse of learner information...
The definition of advanced and distributed management frameworks is one of the key research issues that still need to be addressed in the network and service management research field. As part of this effort, the use of Web service technologies provides some advanced features such as improved interoperability and flexibility. This paper describes the main requirements and key components of a Web service-based...
As a macro complex systematic engineering, the Digital Ocean project is an ongoing task in china. The mission of the Digital Ocean is to build an interactive network information system based on a three-dimensional globe. The Digital Ocean can help provide integrated information on historical, current and future states of ocean and coastal zone. This paper addresses the architecture of Digital Ocean,...
Distributed software systems are characterized by increasing autonomy. They often have the capability to sense the environment and react to it, discover the presence of other systems and take advantage of their services, adapt and re-configure themselves in accordance with the internal as well as the global state. Testing this kind of systems is challenging, and systematic and automated approaches...
We developed a quality of service (QoS) management system to support service level management (SLM) for global enterprise services. The QoS management system is integrated with one of our enterprise services in a preproduction system, an identical system as the production system but in a test environment. Lab experiments showed that our integrated solution helps global enterprise services to better...
