【摘要】：隨著互聯(lián)網(wǎng)的發(fā)展與普及,網(wǎng)絡(luò)早已經(jīng)成為了當(dāng)代人們生活、工作和娛樂學(xué)習(xí)等各個方面的基礎(chǔ)支持之一。然而,現(xiàn)有的網(wǎng)絡(luò)架構(gòu)已經(jīng)越來越難以滿足個人、企業(yè)及運(yùn)營商的需求。OpenFlow,這種集中式網(wǎng)絡(luò)體系架構(gòu)順應(yīng)時代的需求逐漸得到了發(fā)展。在這種新型網(wǎng)絡(luò)體系架構(gòu)下,云計算,網(wǎng)絡(luò)虛擬化等等技術(shù)也有了快速的發(fā)展。本文基于OpenDayLight開源控制器,以網(wǎng)絡(luò)虛擬化為目標(biāo),利用OpenFlow網(wǎng)絡(luò)控制器集中控制網(wǎng)絡(luò)的特性,統(tǒng)一管理底層物理網(wǎng)絡(luò),進(jìn)行網(wǎng)絡(luò)虛擬化,為上層業(yè)務(wù)控制器提供一個虛擬的網(wǎng)絡(luò)環(huán)境。為了更好地提供網(wǎng)絡(luò)虛擬化服務(wù),本文通過讀取數(shù)據(jù)庫配置來動態(tài)分配虛擬網(wǎng)絡(luò)資源,模擬交換機(jī)連接為上層的業(yè)務(wù)控制器提供了標(biāo)準(zhǔn)的OpenFlow協(xié)議接口,下發(fā)初始流表至底層交換機(jī)對數(shù)據(jù)平面的流量進(jìn)行隔離。處理交換機(jī)與控制器之間的控制消息,完成對網(wǎng)絡(luò)資源的隔離。然后,本文詳細(xì)描述了支持多協(xié)議虛擬網(wǎng)絡(luò)控制管理組件的設(shè)計與實現(xiàn),主要包括虛擬化控制器與擴(kuò)展交換機(jī)接口,虛擬網(wǎng)絡(luò)配置管理,控制消息的處理,多協(xié)議配置與網(wǎng)絡(luò)管理可視化接口等。最后,論文給出了一系列的系統(tǒng)測試方案和測試結(jié)果分析,對多協(xié)議解析功能、虛擬網(wǎng)絡(luò)資源隔離以及虛擬網(wǎng)絡(luò)業(yè)務(wù)支持功能進(jìn)行了驗證。
[Abstract]:With the development and popularization of the Internet, the Internet has already become one of the basic support of modern people's life, work and entertainment study and so on. However, the existing network architecture has become more and more difficult to meet the needs of individuals, enterprises and operators. OpenFlow. this centralized network architecture has gradually developed to meet the needs of the times. In this new network architecture, cloud computing, network virtualization and other technologies also have a rapid development. Based on OpenDayLight open source controller and network virtualization, this paper makes use of the characteristics of OpenFlow network controller to control the network centrally, manages the underlying physical network uniformly, and implements network virtualization. Provides a virtual network environment for the upper layer service controller. In order to better provide network virtualization service, this paper dynamically allocates virtual network resources by reading database configuration, and simulates switch connection to provide standard OpenFlow protocol interface for upper layer service controller. Send down the initial flow table to the underlying switch to isolate the traffic in the data plane. Handle the control message between the switch and the controller to isolate the network resources. Then, this paper describes the design and implementation of supporting multi-protocol virtual network control management component in detail, including virtualization controller and extended switch interface, virtual network configuration management, control message processing. Multi-protocol configuration and network management visual interface. Finally, a series of system test schemes and test results are presented, and the functions of multi-protocol resolution, virtual network resource isolation and virtual network service support are verified.
