基于微通信元系统构架的支持QoS路由器原型的设计与实现
摘要
现在对网络体系结构的研究表现在两个方面,一个是在TCP/IP体系结构上进行改进,难以解决层次结构自身存在的问题。另一种研究就是针对现在网络通信技术发展的特点,结合网络应用的需要,进行新型网络体系结构的研究,这是解决层次网络体系结构存在问题的根本途径。
本文介绍了一种新型的网络体系结构-服务元网络体系结构,主要分析了服务元网络体系结构的特点、节点模型、服务元的定义以及提供的服务等。并引出了微通信元系统构架,这是基于服务元网络体系结构的第一个网络系统,是服务元网络体系的具体实现。
我的这篇论文主要讲述了基于微通信元构架的支持QoS的路由器原型的设计和实现,目标是在PC机上模拟实现基于微通信元系统构架的支持QoS路由器模型,在数据包的传送过程保证服务质量。
全文分为七章。首先介绍了服务元网络体系结构;接着介绍微通信元系统构架的参考模型;第三章介绍了QoS概念和QoS技术;第四章则介绍了基于微通信元系统构架对QoS的支持;第五章介绍了基于微通信元系统构架对QoS的支持的路由器原型的设计和实现;第六章介绍了该路由器原型的测试方法及测试结果。第七章进行了全文总结。
本论文具有原创性。包括两个方面,不仅是新型网络体系结构是原创的,而且对QoS的支持也是原创的。
At the present time, the practical network structures are all layered architecture, and TCP/IP dominates the internet. TCP/IP was developed for narrowband text transfer.Now, with the rapid development of global internet,people avail the network and depend on it more and more, but because of the original designing mechanism,the layered architecture can't satisfy peoples demand correspondingly,and the disadvantage of TCP/IP becomes obvious in such cases.This paper introduces a Service Unit based Network Architecture (SUNA), and mainly analyses the features of the structure, then the Micro Communication Element System (MCES) is educed, that is the first network system instance presented for SUNA.This paper describes how to design and realize the router model supporting QoS, which is based on the MCES, and its target is to realize the router model in PC machine. There are seven chapters in all. Fisrtly, SUNA is overviewed; Then, MCES is outlined; Chapter Three introduces QoS concept and techniques; Chapter Four shows how MCES supports QoS; Chapter Five introduces the design and realization of the router model; Chapter Six depicts the test method and result about the router model; Finally, Chapter Seven summarises the whole work.This paper is originally creative, it includes two parts: one is that SUNA is originally creative; the other is that support to QoS is originally creative, too.
