摘　　要：访问网格(AG)基于开放网格服务体系结构,结合视频会议、网络、网格等技术集成,从而建立起群组可视化交流环境,它是网络、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,它包含许多不同格式的多媒体内容显示、演示和交互软件环境,也存在着大量的网格中间件接口和远程可视化环境。但随着网络技术的进步,用户对AG提出更高的要求,而且需要普及。为此,充分考虑Web和P2P设计出下一代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、异步协作进行研究。AG将不仅向使用几十年的桌面应用模式提出挑战,而且在网格其它相关技术的支持和推动下,将支持用户顺畅地与多个异地同事保持同时在线,又为用户提供结构化会议的空间,最终成为网格环境下广域交互的主流。The access grid （AG） is the servicing architecture based on open-grid, combining the video conference, network, and grid to form the group video communication circumstance. It is the integrality of computational ability and the resource exchanging. Now, the first AG has been becoming the biggest group cooperation experimental flat in history, which including different format multimedia display, demonstration, mutual software circumstance, ports for middleware, and long range video circumstance. The users put forward more requests in AG as the grid technology progress. Hence, it is necessary for the designing the next AG2 frame by considering the Web and P2P. The virtual ground service, security, and interlinkage of working space, management of nodes, asynchronism cooperation in the AG2 are emphasized. As the supporting and promoting by the other technology of grid, the AG technology will not only challenge the traditional desktop application mode in the future, but also can support more users keeping in touch with his workmates located different place on line swimmingly, also can providing the space of architectural conference for users. It will be main flow of wide area communication on the network.
