基于代理的资源请求中间件的实现

Implementation of resource request middleware based on agent

针对网格资源管理中资源请求问题,提出一种基于代理的中间件实现方案。用户作业信息和需求由客户端通过https协议传输给网格数据库,并触发网格资源请求代理做出相应的动作。基于代理的资源请求中间件负责查询资源信息服务器,为用户在整个网格中寻找合适资源,同时对用户提交的作业进行调度。网格服务端(资源提供方)动态向信息服务器注册资源信息,资源请求代理通过向信息服务器查询,可获取当前网格中的各种实时资源,也可以向网格服务端直接查询其当前的资源情况。对基于代理的中间件的工作机制和实现方法也作了说明。

To deal with the resource request problem, we propose a middleware realization method based on agent. The information of user jobs and requirements are safely transmitted to the grid database by the client through https protocols. Then they trigger the grid request broker to act correspondingly. The resource request middleware based on agent is responsible for querying the resource information sever, finding the appropriate resource for the users from the whole grid, and scheduling the jobs submitted by the users. The grid sever （the resource provider） dynamically registers resource information to the information sever. By querying the information sever, the resource request broker can get all sorts of real-time resources in the current grid. It can also query the grid sever directly to get the information in the current grid. The work mechanism and implementation techniques of the middleware based on agent are also illuminated.
