What was needed was a remote transport technology that combined the small footprint of java s rmi remote method invocation and the sturdiness of the more mature corba common object request broker architecture technology 所需要的就是一种远程传输技术，它兼有java的rmi （ remote method invocation ，远程方法调用）较少的资源占用量和更成熟的corba （ common object request broker architecture ，公共对象请求代理体系结构）技术的健壮性。
Multithreading is a kind of important feature for real - time ability of a general operating system , and at the same time it provides a solution to implement the concurrency ability of orb ( object request broker ) core and a effective way to control computing resources for a real - time orb 多线程机制是通用操作系统平台实时能力的一个重要方面，并且为orb ( objectrequestbroker ，对象请求代理)内核支持并发和实时orb控制计算资源提供了有效的解决途径。
Based on no - preemptive priority queuing network model , new infinitesimal perturbation analysis schemes were presented to estimate the dynamic time performance of dms based on common ojbect request broker architecture ( corba ) and dimensional measurement interface standard ( dmis ) 针对基于公共对象请求代理结构和尺寸测量接口规范的分布式测量系统，根据多用户非抢占优先排队网络静态性能模型，提出基于无穷小摄动分析的分布式测量系统动态性能评价算法。
Thirdly , integration of spatial data based on corba is explained in detail . the object of corba transfer mechanism is analyzed , including client , the implement of object and agent of object request , the strategy and structure of corba ' s mechanism is concerned 分析了corba的对象调用机制包括客户、对象实现和对象请求代理三大部分，对corba的集成实现策略和结构进行了剖析，认为corba能够最大限度地满足异构和多层次的网络环境下webgis系统的开发。
In this paper , we expatiate on the mechanism of the implement of aaa by the peculiarities of the structure of hfc , and narrate the role of corba in the community network management , and analyze the use of corba in the aaa management . moreover , we are able to provide design model of aaa management 本文根据hfc网络特点阐述了其aaa的实现机制，并且阐述了通用对象请求代理体系结构（ commonobjectrequestbrokerarchitecture ， corba ）在网络资源管理系统中的地位，以及详细的分析了aaa的整体框架和实现。
With the development of computer technology and modern communication technology , the network and component technology are widely used in the automation software of power system . the process bus of substation bay level and power utility integration bus of control center , thus , will be interconnected . a lot of soap - based technology , such as corba , ejb , dcom and xml web service , will be applied on power system automation & control 随着计算机技术和现代通讯技术的飞速发展，电力系统自动化软件业正在掀起网络化、组件化的浪潮，从厂站侧间隔级的过程总线到主站侧的电力系统企业集成总线将全面组网和互联， it流行的公共对象请求代理体系结构corba ( commonobjectrequestbrokerarchitecture ) 、企业java组件ejb ( enterprisejavabeans ) 、分布式对象组件模型dcom ( distributedcomponentobjectmodel )和基于简单对象访问协议soap ( simpleobjectprotocol )的xmlwebservices等组件模型开始运用于电力系统自动化的解决方案。
In this thesis , the work mode of dispatching command sheet based on advanced three - tier browser / server has been put forward and established , furthermore steps and methods based on corba have been summed up through analyzing in detail the foundation mechanism of dispatching command sheet and lucubrating popular distributing component technology , especially corba ( common object request broker architecture ) technology . applying methods above , an architecture of dispatching command sheet expert system based corba and on - line data has been presented , and several modules have been designed and implemented , including knowledge base management module , dispatching command sheet management module , user security management module and statistic information management module etc . in the thesis , two following aspects have been discussed about dispatching command sheet expert system : firstly , aiming at it ' s reliability , a scheme combining on - line and off - line expert system has been put forward 本文结合实际科研项目的开发过程，总结国内外对此类系统的研究成果，通过对电厂操作票建立机制的全面分析，并对当前流行的组件技术，特别是corba (公用对象请求代理结构)技术进行了深入研究之后，提出和建立了一套基于先进的三层b s体系结构的操作票专家系统工作模式，总结出了开发corba应用程序的步骤和方法，在此基础上设计并实现了包括知识库管理、操作票管理、用户安全管理及统计信息管理等在内的主要功能模块。
The user ' s vision is one directly presented by edge switches , while the backstage server is invisible to users . the two - vision view is helpful to appreciate the working principle and has guided the implementation described in this dissertation . another contribution to system representation involves clarification of the function of the authenticator system , i . e . as a server agent at the client side and as a client agent at the server side 本论文对802 . 1x认证服务的工作过程采用了客户机/服务器的应用系统模式的观点来进行描述，较清晰地反映出处于“运营商域”内认证代理系统的双重功能：在客户系统侧扮演认证服务器代理的角色和在认证服务器侧扮演客户认证请求代理的角色。
It gives the description of an existing system finished based on the analysis above , which deals the global data and the local data with three kinds of methods which include : processing directly with relational data ; first changing it into object type then storing it into oracle database with some modal data which can not be classified into relational data ; and to some data which is not easy to change into object type , integrating it through open i - deas " s object oriented interfaces based on corba 该系统对oracle数据库系统管理的全局数据与大型cad软件i - deas管理的局部数据分为三种情况进行的集成处理：对关系型数据直接进行集成；对部分非关系型模型数据先进行对象化，再按照oracle中对象类型数据的方法进行存储集成；对于难以对象化的模型数据，通过openi - deas提供的公共对象请求代理体系结构corba对象接口进行集成。
Then , we introduce the common object request broker architecture . base on these research , bring forward the design of new distributing transmission unify network management platform base on the component technology . we describe in detail the platform ’ s truss model , the public model design , the structure of system model , the running structure , the command and message processing flow , the component illuminate of server subsystem and the client subsystem 然后介绍了分布式对象请求代理体系( corba ) ,在此基础上介绍了中兴通讯新一代的基于组件技术的分布式传输统一网络管理平台的设计,详细描述了统一网络管理平台的架构模型、公用模块设计、系统模块结构、运行结构,命令和通知处理流程、服务器子系统和客户端子系统的构件说明。
