【摘要】：隨著網(wǎng)絡(luò)通信業(yè)務(wù)尤其是實(shí)時(shí)業(yè)務(wù)的不斷發(fā)展,用戶對(duì)網(wǎng)絡(luò)數(shù)據(jù)傳輸?shù)馁|(zhì)量和可靠性提出了越來(lái)越高的要求。為此人們進(jìn)行了不懈的努力去提高網(wǎng)絡(luò)的物理性能,其中包括對(duì)網(wǎng)絡(luò)設(shè)備進(jìn)行升級(jí),增加網(wǎng)絡(luò)帶寬等直接投資擴(kuò)充網(wǎng)絡(luò)的方法,顯然這種方法需要付出昂貴的代價(jià)。本論文給出另外一種方法,稱為多路徑通信方法,可以在不增加網(wǎng)絡(luò)容量情況下提高用戶體驗(yàn),從而提高網(wǎng)絡(luò)服務(wù)的性價(jià)比。利用多路徑傳輸可以顯著提高網(wǎng)絡(luò)傳輸?shù)馁|(zhì)量以及魯棒性,然而IP網(wǎng)絡(luò)并不能很好的支持多路徑傳輸,嚴(yán)重限制了這種方法的實(shí)施。為此,本文采用了一種網(wǎng)絡(luò)新技術(shù),即向量網(wǎng)(VectorNetwork,VN),它是一種分形體系架構(gòu)的、以向量地址為基礎(chǔ)的新型數(shù)據(jù)通信網(wǎng),不僅非常適合多路徑傳輸,而且多路徑傳輸幾乎不增加成本。VN根據(jù)向量地址確定數(shù)據(jù)轉(zhuǎn)發(fā)路徑,以無(wú)連接的代價(jià)實(shí)現(xiàn)有連接的效果,本身的多路徑特性決定了其比其它網(wǎng)絡(luò)可以更好的支持多路徑通信。本文在分析了現(xiàn)有的多路徑通信方法基礎(chǔ)上,結(jié)合向量網(wǎng)的諸多特征,設(shè)計(jì)了一種VN交換網(wǎng)絡(luò)的多路徑通信方法。主要工作和成果是:(1)設(shè)計(jì)了多路徑通信的基本方法,其中主要包括傳輸路徑故障發(fā)現(xiàn)方法以及丟包重傳機(jī)制。采用端對(duì)端的傳輸路徑故障發(fā)現(xiàn)方法可以在很大程度上減少傳統(tǒng)路徑故障檢測(cè)方法的開銷;通過在端系統(tǒng)定量緩存數(shù)據(jù)包,在路徑切換時(shí)實(shí)現(xiàn)快速重傳,可以有效減少由于路徑故障所產(chǎn)生的丟包。(2)設(shè)計(jì)了主路徑傳輸和多路徑輪流傳輸兩種不同的多路徑傳輸策略,以滿足不同業(yè)務(wù)的傳輸需求。并在充分分析不同傳輸策略優(yōu)缺點(diǎn)的基礎(chǔ)上,針對(duì)實(shí)時(shí)流媒體以及域名服務(wù)等應(yīng)用的傳輸特點(diǎn),分別設(shè)計(jì)了相應(yīng)的多路徑傳輸方案。(3)通過網(wǎng)絡(luò)編程對(duì)所提出的兩種多路徑傳輸策略進(jìn)行了網(wǎng)絡(luò)仿真實(shí)驗(yàn),驗(yàn)證了本文設(shè)計(jì)的多路徑傳輸策略的可行性,同時(shí)也證明了本文提出的故障發(fā)現(xiàn)算法和丟包重傳機(jī)制的合理性,達(dá)到了提高網(wǎng)絡(luò)傳輸質(zhì)量以及魯棒性的目的。
[Abstract]:With the continuous development of network communication services, especially real-time services, users put forward higher and higher requirements for the quality and reliability of network data transmission. Therefore, people make unremitting efforts to improve the physical performance of the network, including upgrading the network equipment, increasing network bandwidth and other direct investment methods to expand the network, it is obvious that this method has to pay a high price. This paper presents another method, called multipath communication, which can improve the user experience without increasing the network capacity and thus improve the performance / price ratio of network services. Using multipath transmission can significantly improve the quality and robustness of network transmission. However, IP network can not support multipath transmission well, which seriously limits the implementation of this method. Therefore, this paper adopts a new network technology, Vector Network VN, which is a new data communication network based on vector address, which is a fractal architecture, which is not only suitable for multipath transmission. Moreover, the multipath transmission almost does not increase the cost. VN determines the data forwarding path according to the vector address, and realizes the effect of connection at the cost of no connection. The multipath characteristic of the multipath determines that it can support multipath communication better than other networks. Based on the analysis of the existing multipath communication methods and the characteristics of vector networks, a multipath communication method for VN switching networks is designed in this paper. The main work and result is: (1) the basic method of multipath communication is designed, which includes transmission path fault detection method and packet loss retransmission mechanism. Using the end-to-end transmission path fault detection method can greatly reduce the overhead of the traditional path fault detection method. It can effectively reduce packet loss caused by path fault. Two different multipath transmission strategies are designed, which are main path transmission and multipath rotation transmission to meet the transmission requirements of different services. And on the basis of analyzing the advantages and disadvantages of different transmission strategies, aiming at the transmission characteristics of real-time streaming media and domain name service, The corresponding multipath transmission scheme is designed respectively. (3) the network simulation experiments of the two proposed multipath transmission strategies are carried out by network programming, and the feasibility of the proposed multipath transmission strategy is verified. At the same time, it also proves the rationality of the proposed fault detection algorithm and packet loss retransmission mechanism, and achieves the purpose of improving the network transmission quality and robustness.
