摘　　要：网格可以看成是一种新兴的基础设施,它为大型的网络服务提供相应的资源支持,即组织大规模分布式的资源,包括计算能力、存储资源和带宽等。网格需要解决网络的异构性、动态性和伸缩性等问题,尤其是网格服务的部署;而网格服务部署的关键是网络拓扑。文中提出了一种用于网格服务部署的拓扑模型。该模型有明显的简单性,且具有动态的、可伸缩的特点,也考虑到了网络的异构性,可以描述那些有不对称链路、防火墙、非IP网络、非分层拓扑等复杂情况的网络拓扑。同时还给出了相应的XML描述。Grid can be considered a new infrastructure as the resource surports for large network service that it organizes distributed resoure including computing,storing capability and bandwith,ete. It is necessary for grid to deal with heterogeneity,dynamics and sealability,speeially in grid service deployment;and the key of the grid service deployment is network topology. Here provide a topology model for deploying grid service, obviously this model is simple,and includes dynamic,scalable and heterogeneous characteristic, so it can describe complex network topology such as asymmetric links, firewalls, non - IP networks and non - hierarchical topologies. And the corresponding XML description is given here.
