An Application Service Provider (ASP) is a business that provides computer-based services to customers over a network. Software offered using an ASP model is also sometimes called On-demand software or Software as a Service (SaaS). The most limited sense of this business is that of providing access to a particular application program (such as customer relationship management) using a standard protocol such as HTTP. In this paper, the authors proposed a novel knowledge extraction mechanism which based on E-delivery pattern. The new mechanism can solve efficiently some problem coming from nodes having data resources but lack of computing power, or some node with computing power but no data resource and low transmission bandwidth.
