Grid computing enables virtual organizations to share geographically distributed resources as they pursue common goals, assuming the absence of central location, central control, omniscience, and an existing trust relationship. A recent survey ranked grid computing as sixth on priority lists for IT spending among industry professionals. This paper details the grid protocol architecture. Workflow is the orchestration of a set of activities to accomplish a larger and sophisticated goal. In this paper, the authors review various workflows and the management of workflow in grids and a data transfer scheme of grid workflow based on weighted directed graph. The scheme selects data transfer model according to the job's data processing rate.
