【摘要】：隨著移動互聯(lián)網(wǎng)的發(fā)展,大數(shù)據(jù)業(yè)務的興起,人們需要一個在任何時間、任何地點以及以任何形式都可以進行通信信寬帶接入網(wǎng),可以說為了應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、防電磁干擾能力強等特性,但傳輸路徑固定、靈活性較差；無線接入方式能夠為用戶提供高度靈活、無處不在的網(wǎng)絡接入,但由于無線自身的特點導致其傳輸數(shù)據(jù)速率受限、易受干擾�？梢哉f光纖通信與無線通信在各自的應用領域都有不錯的發(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,將兩個技術進行融合,優(yōu)勢互補,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融合的網(wǎng)絡。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)技術的熱點之一,其中具代表性的是融合接入網(wǎng),它是基于無線Mesh網(wǎng)絡和PONFiWi (Fiber-Wireless)無源光網(wǎng)絡)的一種光與無線融合組(Passive Optical Network,網(wǎng)。雖然關于光與無線融合接入網(wǎng)已經(jīng)得到了廣泛關注,有較好的發(fā)展前景,但關于其組網(wǎng)問題業(yè)界尚無統(tǒng)一定論。網(wǎng)絡虛擬化技術為融合問題提供了一種解決方案。網(wǎng)絡虛擬化技術將互聯(lián)網(wǎng)服務提供商)分離為兩大獨立的部分：InPISP (Internet Service Provider,基礎設施提供商)和(Infrastructure Provider,Provider,服務提供商),真正意義上實現(xiàn)了控制與轉發(fā)分離。SP (Service本文首先分析了當前接入網(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)的研究進展做了詳細的介紹,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)架構以及網(wǎng)絡虛擬化FiWi模型,并結合具體的多路徑接入問題闡述網(wǎng)絡虛擬化技術的應用,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技術進行組網(wǎng)來驗證虛擬網(wǎng)絡之間的隔離性并對FiWi網(wǎng)絡多路徑接入的網(wǎng)絡性能進行了仿真,驗證了基于網(wǎng)絡虛擬化技術的FiWi融合接入網(wǎng)的優(yōu)越性能。在最后對本文所做工作進行了總結并對未來接入網(wǎng)的發(fā)展進行了展望。
[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.
