This paper introduces basic principles of policy - based network concept to simplify the management of ip qos network 本文引入了基于策略的網絡管理機制來簡化對ipqos的管理。
As a basic mechanism for providing qos in ip network , diffserv architecture have a great deal of advantages to network operation Diffserv體系作為ipqos的一種實現(xiàn)帶給網絡運營諸多好處,但是它的實現(xiàn)會增加ip網絡的管理負擔。
With the rapid transformation of the internet into a commercial infrastructure , demands for service quality have rapidly developed Ipqos的解決對于提高ip電話的服務質量至關重要。 diffserv模型被認為是當前效率和擴展性最好的ipqos解決方案。
Finally , this paper will conclude with the qos issue , comparing the major qos models , exploring various implementation approaches on the application level 最后討論端到端的qos保證,對主要的ipqos模型進行比較分析,探討了應用層實現(xiàn)qos的各種實現(xiàn)方案。
In chapter 2 , we mainly introduce two well - found ip qos models : the intserv and the diffserv , and do some transverse comparative works on their advantage and disadvantage 第二章中簡單介紹了intserv和diffserv兩種比較成熟的ipqos服務模型,并對它們的優(yōu)缺點進行橫向比較。
To solve the problem , many blue prints of ip qos have been brought forward at present , among which there are three representational theories : intserv , diffserv and mpls 針對這一問題,目前已經有了很多解決ipqos的方案,其中比較有代表性的理論是intserv , diffserv和mpls三種。
On the basis of study on various kinds of implements of qos and policy - based network management model , this paper addresses the design and the partial implementation of policy - based qos management framework in diffserv netwoks 在對各種qos實現(xiàn)機制進行研究的基礎上,結合基于策略的網絡管理模型,設計并部分實現(xiàn)了基于策略的ipqos網絡管理框架。
At last , this paper analyzes the time delay problem existing in the most remote control robot system based on the internet , and discusses the feasibility and rationality of a method based on ip qos technology 最后,本文就基于internet的遠程控制機器人系統(tǒng)普遍存在的時間延遲問題進行了細致的分析,并探討了一種基于ipqos技術的解決方案的可行性與合理性。
Diffserv model is one important model of the ip qos , this model works on the basis of packet classification granularity , so it can overcome the limitation of the intserv / rsvp model and it is easy to be realized on the big networks Diffserv模型是當前實現(xiàn)ipqos的主要模型之一,這一模型工作在分組類的粒度上,克服了intserv rsvp模型在分組流粒度工作上的缺陷,因而容易在大規(guī)模網絡上實現(xiàn)。
In chapter 5 , we expatiate a new mixed architecture of ip qos model , which uses mpls as its main body and uses the advanced ideas of intserv & diffserv as its assistant . mainly focus on the idea in design and the architecture of the model 第五章中以mpls為框架,以intserv和diffserv的模型中比較先進的思想為輔助,提出一種新的混合式的ipqos服務模型,并著重分析了模型的設計思想和體系結構。
