Context Management Model Of Internet-ware Supporting Environment Shanghai Jiao Tong University

As development of Internet, more and more people treat it not just a information platform, but a computing platform with huge potential. So, static, closing computing environment is no longer suit for the software nowadays. In order to tackle the challenges bring by new computing environment, the distributed computing paradigm is become a hot research area. Many new computing model and related methods and technologies have been proposed by different researchers and experts, includes grid computing[3], Ubiquitous computing[4] and Web Services[5] and so on. The most recent one is the concept of Internetware[1] which is proposed by researchers from Peking University and Nanjin University.In the area of Internetware, context acquisition is the basic of aggregation and evolving of the Internetware, but most researches is focus on how service entities aggregate to form Internetware and how a service entity adjust its behaviors with the changing environment, but no systematized and practical achievements for how to represent Internet context, how to aware Internet context and how to manage Internet context.This paper proposes an Internet context awareness model which used to support the development, deployment and running of Internetware. First, we use the Ontology method to modeling the context in Internetware paradigm. Then, an extensible context management framework was proposed to help service entities in Internetware paradigm to access and operate the context. In this framework, we extend the Probe-Gauge mechanism to collect context in Internetware environment, and we use ontology library to maintain and store such context. Meanwhile, in order to let other applications can access the context without knowing the detail of how the context was stored, we also provide accessing interfaces.
