Current development of network infrastructures is undergoing rapid transformation. With the emergence of the Open Grid Service Architecture and Globus Toolkit as incubators for evolving ASP business model to maintain profitability, this paper presents an in-depth analysis of the hypothetical Grid Service Provision (GSP) model by firstly giving an historical account of evolutionary factors in Internet architectures leading to Grid and P2P and secondly, investigating GSP model in the contexts of Service Level Agreements metrics and GSP implementation details. It is acknowledged by some experts that this hypothetical model is technologically feasible in reality.
