RGPS

Abstract

Networked software, a special kind of applications in service-oriented computing and ultra-large-scale systems, is a complex software system deploying on network environment. Requirements engineering of networked software poses many problems owing to the dynamic topology structure, users' uncertainty, and continuous growing requirements. Towards these problems, a unified requirements meta-modeling frame for networked software named RGPS is proposed by merging functional and nonfunctional requirements. Particularly, two kinds of nonfunctional requirements, context and trustworthy requirements, are taken into account in this paper. RGPS serves as a unified basis for requirements engineering of networked software. Meta-models of the RGPS frame are introduced in detail. In addition, a case study in urban transportation domain is illustrated to explain the RGPS frame.
