【摘要】：隨著移動互聯(lián)網(wǎng)的發(fā)展,大數(shù)據(jù)業(yè)務(wù)的興起,人們需要一個在任何時間、任何地點(diǎn)以及以任何形式都可以進(jìn)行通信信寬帶接入網(wǎng),可以說為了應(yīng)對用戶日益增長的需求下一代接入網(wǎng)面臨著較大的挑戰(zhàn)。目前較常用的接入技術(shù)主要有光纖接入和無線接入。光纖接入的方式可以提供足夠大的帶寬,并且具有較低的誤碼率、防電磁干擾能力強(qiáng)等特性,但傳輸路徑固定、靈活性較差；無線接入方式能夠?yàn)橛脩籼峁└叨褥`活、無處不在的網(wǎng)絡(luò)接入,但由于無線自身的特點(diǎn)導(dǎo)致其傳輸數(shù)據(jù)速率受限、易受干擾。可以說光纖通信與無線通信在各自的應(yīng)用領(lǐng)域都有不錯的發(fā)展,但是如何能夠滿足用戶日益增長的需求,為用戶提供高性價比的服務(wù),將兩個技術(shù)進(jìn)行融合,優(yōu)勢互補(bǔ),是業(yè)界面臨的問題之一。為了解決光接入方式與無線接入方式各自的不足,提出了光接入與無線接入異構(gòu)融合的網(wǎng)絡(luò)。目前,光與無線融合是國際上研究與開發(fā)的下一代接入網(wǎng)技術(shù)的熱點(diǎn)之一,其中具代表性的是融合接入網(wǎng),它是基于無線Mesh網(wǎng)絡(luò)和PONFiWi (Fiber-Wireless)無源光網(wǎng)絡(luò))的一種光與無線融合組(Passive Optical Network,網(wǎng)。雖然關(guān)于光與無線融合接入網(wǎng)已經(jīng)得到了廣泛關(guān)注,有較好的發(fā)展前景,但關(guān)于其組網(wǎng)問題業(yè)界尚無統(tǒng)一定論。網(wǎng)絡(luò)虛擬化技術(shù)為融合問題提供了一種解決方案。網(wǎng)絡(luò)虛擬化技術(shù)將互聯(lián)網(wǎng)服務(wù)提供商)分離為兩大獨(dú)立的部分：InPISP (Internet Service Provider,基礎(chǔ)設(shè)施提供商)和(Infrastructure Provider,Provider,服務(wù)提供商),真正意義上實(shí)現(xiàn)了控制與轉(zhuǎn)發(fā)分離。SP (Service本文首先分析了當(dāng)前接入網(wǎng)的發(fā)展需求以及對下一代接入網(wǎng)提 出的挑戰(zhàn),并對下一代接入網(wǎng)的研究進(jìn)展做了詳細(xì)的介紹,包括下一代無線接入網(wǎng)以及下一代光接入網(wǎng),通過分析闡述下一代光與無線融合接入網(wǎng)發(fā)展的必然趨勢。本文重點(diǎn)研究對象是融合接入網(wǎng),FiWi在第三章提出了光與無線融合接入網(wǎng)組網(wǎng)架構(gòu)以及網(wǎng)絡(luò)虛擬化FiWi模型,并結(jié)合具體的多路徑接入問題闡述網(wǎng)絡(luò)虛擬化技術(shù)的應(yīng)用,以及虛擬資源管理控制器的工作流程。本文在第四章利用SDN/OpenFlow技術(shù)進(jìn)行組網(wǎng)來驗(yàn)證虛擬網(wǎng)絡(luò)之間的隔離性并對FiWi網(wǎng)絡(luò)多路徑接入的網(wǎng)絡(luò)性能進(jìn)行了仿真,驗(yàn)證了基于網(wǎng)絡(luò)虛擬化技術(shù)的FiWi融合接入網(wǎng)的優(yōu)越性能。在最后對本文所做工作進(jìn)行了總結(jié)并對未來接入網(wǎng)的發(fā)展進(jìn)行了展望。
[Abstract]:With the development of mobile Internet, the rise of big data business, people need one at any time, any place, in any form can communication channel broadband access network, it can be said in response to the growing demand of users in next generation network is facing greater challenges. Currently more commonly used optical fiber access technology access and wireless access. Optical access can provide enough bandwidth, and has low BER, anti electromagnetic interference ability and other characteristics, but the transmission path is fixed, poor flexibility; wireless access mode can provide users with highly flexible and ubiquitous network access, but because of their own due to the characteristics of wireless the data transmission rate is limited, vulnerable to interference. It can be said that the optical fiber communication and wireless communication have a good development in their respective application domain, but how to meet the users The growing demand, to provide high quality service for the users, the two technology integration, complementary advantages, is one of the industry's problems. In order to solve the problems of optical access and wireless access of the proposed optical access and wireless access in heterogeneous network. At present, optical and wireless converged is one of the hot spots the research and development of next-generation access network technology in the world, which is representative of the converged access network, which is based on PONFiWi and wireless Mesh network (Fiber-Wireless) passive optical network) is a kind of optical and wireless converged group (Passive Optical Network, while on the network. Optical and wireless converged access network has been attention, there are good prospects for development, but on the networking industry. There is no unified theory of network virtualization technology for fusion provides a solution for network virtualization technology will be. The network service provider) is separated into two independent parts: InPISP (Internet Service Provider, infrastructure providers (Infrastructure) and Provider, Provider, service provider), to achieve a true sense of separation of control and forwarding.SP (Service in this paper the development needs of the current access network and the next generation network.
The challenges and research progress of the next generation network is introduced in detail, including the next generation of wireless access network and the next generation optical access network, through the analysis of the trend of the next generation of optical and wireless converged access network development. The research object of this paper is focused on integration of access network, FiWi proposed optical network architecture and wireless integrated access network and network virtualization FiWi model in the third chapter, combined with the application of multi path access specific description of network virtualization technology, and workflow of virtual resource management controller. In the fourth chapter of this paper is to verify the performance of the network virtual network between the network and the access path isolation the FiWi network is simulated using SDN/OpenFlow technology to verify the superior performance of network virtualization technology FiWi integration based on access network. In the end of the paper, we summarize the work and The development of the future access network is prospected.
