Network - based collaborative design ( ncd ) is a new design pattern . during this process a design team devises a product concurrently and cooperatively , aiming at team work , and aided by a distributive collaborative environment provided by computer communication network 網(wǎng)絡(luò)化協(xié)同設(shè)計(jì)是一種新的設(shè)計(jì)模式,是指一個(gè)產(chǎn)品開發(fā)團(tuán)隊(duì),在計(jì)算機(jī)通信網(wǎng)絡(luò)提供的分布式協(xié)同環(huán)境支持下,以群體工作目標(biāo)為核心,并行、協(xié)同地設(shè)計(jì)產(chǎn)品的過程。
Furthermore , with regard to the flow regulation of multicast flows in high - speed computer communication networks , the present paper proposes a class of sender - driven single rate congestion controllers based on a many - to - many multicast model 接著,本文針對(duì)計(jì)算機(jī)高速互聯(lián)網(wǎng)中組播的速率調(diào)節(jié)問題,在多點(diǎn)對(duì)多點(diǎn)的組播流量模型基礎(chǔ)上,提出了一類新的由發(fā)送方驅(qū)動(dòng)的單速率組播擁塞控制器pid ( proportionalintegrativeplusderivative )的設(shè)計(jì)方案。
In the contemporary computer communication networks , with continuous expandability of the networks data business , it is neccesary and objective for the clients to provide to guarantee both quality and quantity service because the traditional service which is charactered by " best of efforts " hatofenot been able to satisfied the more and more business service demands 在當(dāng)代的計(jì)算機(jī)通訊網(wǎng)絡(luò)中,隨著網(wǎng)絡(luò)數(shù)據(jù)業(yè)務(wù)的不斷擴(kuò)大,由于在傳統(tǒng)意義上的盡力而為服務(wù)已經(jīng)不能滿足越來越多的業(yè)務(wù)需求的要求,這樣,為客戶提供保質(zhì)保量的服務(wù)已經(jīng)是網(wǎng)絡(luò)服務(wù)的一個(gè)客觀要求。
With regard to the flow regulation of the best - effort traffic , the controllable traffic in high speed computer communication networks , the present paper proposes a novel control theoretic approach that designs a proportional - integrative ( pi ) controller based on multi - rate sampling for congestion controlling . based on the traffic model of a single node and on system stability criterion , it is shown that this pi controller can regulate the source rate on the basis of the knowledge of buffer occupancy of the destination node in such a manner that the congestion - controlled network is asymptotically stable without oscillation in terms of the buffer occupancy of the destionation node ; and the steady value of queue length is consistent with the specified threshold value 本文從控制理論的角度出發(fā),針對(duì)計(jì)算機(jī)高速互聯(lián)網(wǎng)中最大服務(wù)交通流即能控交通流的調(diào)節(jié)問題提出了一種基于多速率采樣的具有比例積分( pi )控制器結(jié)構(gòu)的擁塞控制理論和方法,在單個(gè)節(jié)點(diǎn)的交通流的模型基礎(chǔ)上,運(yùn)用控制理論中的系統(tǒng)穩(wěn)定性分析方法,討論如何利用信終端節(jié)點(diǎn)緩沖占有量的比例加積分的反饋形式來調(diào)節(jié)信源節(jié)點(diǎn)的能控交通流的輸入速率,從而使被控網(wǎng)絡(luò)節(jié)點(diǎn)的緩沖占有量趨于穩(wěn)定;同時(shí)使被控網(wǎng)絡(luò)節(jié)點(diǎn)的穩(wěn)定隊(duì)列長(zhǎng)度逼近指定的門限值。
