Being associated with the project " capp system in network for chengdu construction machinery group company " which we developed with sichuan university , author participated in the design and development of capp system . configuration and an implementing scheme of distributed process resources management system for mechanical manufacturing is also put forward 本文以我们与四川大学合作开发的“成都工程机械(集团)公司网络化capp系统”项目为背景，参与了capp系统的方案设计和开发工作，同时针对制造工艺资源信息管理系统的实际需求，提出了建立制造工艺资源的分布式管理系统的体系结构和实施方法。
Beside of related knowledge and key technologies about vod system , this paper describes several aspects bellowed : 1 a kind of architecture of distributed vod system ; 2 detailed design of every part of distributed vod system ; 3 design and implementation of distributed managing server ; 4 design and implementation of client 本文出了介绍视频点播系统的相关知识和关键技术外，重点描述了作者在以下几个方面的工作： 1 、一种分布式视频点播系统的体系结构2 、分布式视频点播系统的各组成部分的详细设计3 、分布式管理服务器软件的设计和实现4 、客户端的设计和实现
Another difficult research point is to develop a com - supported web server which can be used and introduced widely in the market . based on the practice , the sub - system of project management solves the problem of data input by the project dispatcher through project templates . the sub - system of project monitor resolves the difficult problem of monitoring the project ' s real - time status by the managers and has a certain analytic function for the statistic data 作为本系统的研究重点，用户管理子系统解决了远程分布式管理用户的问题；另一个开发难点是支持插件的web服务器，它具有较好的应用推广价值；项目管理子系统从实际出发，利用项目模板的形式解决了项目调度人员在创建项目时的数据录入问题；项目监控子系统解决了各级管理人员监控项目进展情况的难点问题，并具有一定的统计分析功能。
As corba does not provide the function of scope , filtering and multi objects or attributes to access , which will cause too much traffics and violate such principle as that management traffic can not affect more on network performance , combined with the advantages of corba and osi management , this article has put forward a mhnm ( multi - hierarchy network management ) architecture in the domain of the management of telecommunications network , using pseudo - agent distributed management and grouping managed objects to cache . it has assured the performance of network management by providing multi object or attributes quick access . 2 针对corba管理本身不支持对象的定界、过滤和多个对象的访问功能，以及在corba管理实用化时，可能导致网管流量急剧增大的不足，基于corba管理与osi系统管理的各自特点，我们提出了一种基于corba的多级网络管理体系结构mhnm ( multi - hierarchynetworkmanagement ) ，该结构结合了osi系统管理与corba的优点，采用pseudo - agent分布式管理和被管对象分类预取值cache技术，提供多对象快速访问的功能支持，解决了corba “单个对象访问”造成的网络管理性能下降问题。
