Theoritically , intserv / rsvp can guarantee real - time services of low latency , small jitter and high quality supplied by ip network . because of its intrinsic defect of awful expansibility , intserv / rsvp cannot apply to the network of large scale . however , diffserv classifies and divides the data streams in the networks , the quantities of status information are proportional to the types of service and independent of the quantities of stream 從理論上來說, intserv rsvp確實能保證ip網絡提供時延低、抖動小、質量高的實時性能服務,但是, intserv rsvp擴展性差等固有的缺點,使其無法應用于大規模網絡;而diffserv對網絡上的數據流進行分類,劃分優先級,其狀態信息量與服務類型數量成正比,而與流的數量無關,伸縮性較好,便于實現,彌補了intserv rsvp的不足。

Also the very important factor quality of service ( qos ) is investigated , the different qos supports in the ip packet switch network are given and analyzed , including intr - serv mode and related rsvp and diff - serv qos mode . the architecture to guarantee the end - to - end qos over the different protocols and different network domains in transmitting the real time vocal data flow is provided 此外,論文對于實時語音數據網絡的服務質量qos保障進行了闡述,對于正在發展的ip網絡qos保障協議包括資源預留協議、區分服務模式和多標簽交換協議進行了探討,并結合語音的ip網絡特點,提出在整個系統中實現端到端的有保障qos的實現方式。

Chapter 1 , we introduce this paper . chapter 2 , we anatomy active signaling and probe particularly . active signaling protocol ( asp ) is an important application in active network . probe is a model to debug and inspect active environment . furthermore , we analyse rsvp and its employmet process . chapter 3 , we bring forward the active signaling and probe model to scout the network state . chapter 4 , we analysys key class and object in the model . chapter 5 , we design programmes for user and deploy it to linux 9 . 0 operating system so we can experiment partly . chapter 6 , we sum up and analysis work for later 在第三章中,我們提出了主動信令和探針的結合模型,并用主動探針對網絡狀態進行監視。在第四章中,我們對于模型中的關鍵類和對象進行了分析。第五章我們對探針程序及用戶端程序進行了設計,并在linux9 . 0中配置ee環境,對本文提出的處理模式進行了部分實驗。

Intserv / rsvp reserves the end - to - end bandwidth and buffers with rsvp signaling protocol to guarantee qos . as the most promising technology at present . diffserv aggregates the data streams of the same type to supply all kinds of services for clients Intserv rsvp利用rsvp信令協議在端到端之間預留帶寬和緩沖區等資源,從而確保所需的服務質量;而作為目前最有發展前途的ip網絡qos支持技術的diffserv ,將具有相同特性的數據流聚合,以向用戶提供若干種類的服務。

A study on signaling mechanism in gmpls traffic engineering is also provided here . a deep analysis and comparison between the two different signaling process rsvp - te and cr - ldp is given , providing a theoretical standard for operators in their choice of signaling protocols 本文還對gmpls流量工程中的信令機制進行了研究,對rsvp - te與crldp兩種信令過程進行了較為深入的分析和比較,為運營商選擇合適的信令協議提供了一定的理論依據。

So many qos mechanism was brought forward , such as one traffic ( or one class ) based qos technology - inteserv diffserv , and macrocosmic qos guarantee - te . rsvp is based on control signal which need save state information , it is more difficult than diffserv 鑒于此,許多支持qos的協議機制被提出,如基于單個(或一類)流量的直接qos機制? ?集成服務( inteserv )和區分服務( diffserv ) ,以及從宏觀上實現整個網絡的qos優化的流量工程( te ) 。

It is possible to setup integrated streams defined perfectly and can be led to pipe with constant bandwidth , if diffserv authenticates and classifies data streams of constant bit rate using the rsvp parameters or according to the types of special application 如果diffserv使用rsvp參數或根據專門應用類型對恒定比特率( cbr )數據流進行鑒別和分類,就可能建立完全定義的綜合流,它能夠被引導成為固定帶寬的管道。

We used this algorithm in our gigabits router and it works well . chapter five compares the differences between two resource reservation protocols used in qos control , rsvp and yessir , ad hoc to implementing complexity and degree of acknowledgement 第五章從應用實際出發,詳細分析和對比了兩種網絡資源預留協議: rsvp和yessir ,就這兩種協議在實現復雜程度、業界認可程度等方面進行了較詳細的分析和對比。

The capability of ip network to carry multimedia has a great progress with development of multimedia compression coding technology and the emergence of some new protocols supporting multimedia communication such as rsvp . rtp / rtcp . rtsp . mms 近幾年,隨著多媒體壓縮編碼技術的發展以及支持多媒體通信的一些新協議如rsvp 、 rtp / rtcp 、 rtsp 、 mms等的出現, ip網絡承載多媒體業務方面的能力已經有相當大的進展。

On the basis of resource reserving method , this thesis give out two level muti _ agents resource manage mechanism , and in order to realize communication among different nodes , it modifies rsvp and cops protocol to contain diffserv model characters 論文中,提出了基于資源預約的兩級多代理的資源管理機制,并改進了rsvp和cops協議來表示diffserv模型的特征,用于實現資源管理時不同節點之間的通信。

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,因而容易在大規模網絡上實現。

Then , we talk about the inside details of this new qos model , describe the interfaces between mpls and prelate rsvp , between mpls and qos routing , between mpls and diffserv , and so on 之后把這一qos服務模型展開,分別闡述了mpls如何同diffserv的集成, mpls如何同qos約束路由的集成以及mpls同輕量級rsvp的接口等。
