Access Grid协作系统研究综述

访问网格（AG）是网络、计算能力和交互资源的整体。目前，第一代AG已经发展并形成有史以来最大的群体协作试验床。但随着网络技术的进步，用户对AG提出了更高的要求，而且需要普及。为此，Rick Stevens和Futures实验小组充分考虑Web和P2P设计了下一代AG2结构，并重点对虚拟场所服务、安全性、工作空间对接、节点管理、异步协作进行了研究。AG将向使用了几十年的桌面应用模式提出挑战。

The Overview of Access Grid Cooperation System

The access grid(AG) is the frame for the network,the ability of computation,and the resource exchanging.Now,the first AG has been becoming the biggest group cooperation experimental flat in history.The users put forward more requests in AG as the grid technology progress.Hence,Rick Stevens and Futures group design the next AG2 frame considering the Web and P2P.The group put emphasize on the virtual ground service,security,and interlinkage of working space,management of nodes,asynchronism cooperation in the AG2.AG technology will challenge the traditional desktop application mode in the future.
