Resource discovery in large scale network infrastructure

Semantic web technologies provide a standardized mechanism for describing and accessing the services of underlying infrastructure. These technologies facilitate the inclusion of the quality of network services in the control loop of high level applications and allow applications to tune the system level performance with additional quality dimensions. However, the descriptions of a large infrastructure are often composed and maintained by different parties and can have different levels of details because of the administration policies. These facts make the development of high level applications unnecessarily difficult. We present a pre-processing framework to hide these difficulties from high level application developers by transforming, integrating, and filtering raw descriptions of the infrastructure into proper information content that these applications need.
