【摘要】 本文论述了基于服务元网络体系结构的实时数据传输的处理。服务元网络体系结构是一种基于服务元的全新型的网络体系结构,它不同于层次网络系统结构,具有简洁、可扩展和容易实现的特点。本文详细阐述了服务元网络体系结构原型主机的总体设计、模块的划分、各模块的功能以及为用户提供的服务。本人的主要工作是完成服务元网络体系结构中的对实时数据传输服务的功能实现。因此,本文中对于实时数据的特性,传统网络中对于实时数据的处理,以及服务元网络体系结构中对于实时数据的处理都进行了深入的研究。服务元网络体系结构中对于实时数据的处理,包括应用程序部分处理及实时传输处理两在部分。对比于传统网络对实时数据的处理,本文详述了服务元网络体系结构中实时传输服务元对实时数据的传输处理,也详细介绍了应用程序部分对于实时数据的处理。并在linux开发环境下,用c语言实现了基于服务元网络体系结构的实时数据的传输服务功能。测试结果表明,在功能上,无论是应用程序部分还是数据传输部分,都能正常实现对实时数据的处理。在性能上,主要测试了实时数据传输部分,测试结果表明服务元网络体系结构下实时数据的传输在性能上优于传统层次网络下实时数据的传输。本文取自于纵向项目XXX创新基金。由于实现基于服务元网络体系结构的实时数据传输原型是前人没有做过的,我们在整个过程中不可避免的遇到了更多的难题,但是通过我们对已有技术的借鉴,各位老师的悉心指导,以及与同项目组同学的积极讨论,这些问题都得到了解决。更多还原

【Abstract】 This thesis has a discussion on the transport of real-time data based on a new network architecture named Service Unit Network Architecture(SUNA). Service Unit Network Architecture is a kind of new network architecture based on the service unit. It is different from the hierarchical architecture and it has simple, easy expanded and easy realized features.This thesis expatiates the total design of the Service Unit Network Architecture, the demarcation and function of the module, and the service provided for users .In the real-time data transport service based on Service Unit Network Architecture,my main task is accomplishing the service of real-time data transport based on Service Unit Network Architecture.Therefore, this thesis focuses on the characteristics of real-time data, the processing of the real-time data in the traditional network and Service Unit Network Architecture.In Service Unit Network Architecture, the processing of the real-time data includes applications software and real-time transport service unit.Contrast in the processing of the real-time data based on traditional network architecture, this paper expatiates the transport processing of real-time data in real-time transport service unit based on Service Unit Network Architecture and present the processing of the real-time data in applications software. I code this program with the c langusge under Linux and the testing result shows that this module can meet the requirement of the user.The finally test result indicates that the performance of the real-time data transport under SUNA is better than that of traditional hierarchical architecture.The task of this thesis come from the xxx creative fund. Because no one has done this prototype host before, we have met some difficulties. We utilized some advanced technology, discussed with our professors and teamates and finally get the solutions.更多还原
