【摘要】：隨著大數(shù)據(jù)時代的來臨,數(shù)據(jù)中心越來越與人們的生活朝夕相關(guān)。而數(shù)據(jù)中心的—個標(biāo)志性技術(shù)就是虛擬化,也就是在一臺實體服務(wù)器上同時配有多臺虛擬機,利用這種技術(shù)可以大大提高服務(wù)器的運行效率。但是服務(wù)器上的數(shù)據(jù)最終要傳輸?shù)矫總�人的手里,于是就要用到網(wǎng)絡(luò)通信設(shè)備,也就是常說的交換機。問題隨之而來,如何去轉(zhuǎn)發(fā)、控制、監(jiān)控這些虛擬機與交換機之間流通的數(shù)據(jù),這就是EVB(802.1Qbg)協(xié)議所產(chǎn)生的原因。 本論文結(jié)合在某網(wǎng)絡(luò)通信公司所做的項目,在EVB協(xié)議的基礎(chǔ)上,在交換機上實現(xiàn)它的主要內(nèi)容,最終目的是實現(xiàn)虛擬機與交換機之間信息交互的一種方法,也就是本文中所提到的S通道的建立。S通道是指,為了在虛擬機與交換機之間同一物理接口上隔離各個交換實體的通道,采用了端口映射的S-Vlan組件技術(shù),將一個物理接口分出的多個虛擬通道。 首先,給出相關(guān)背景知識的介紹并結(jié)合實際硬件及軟件開發(fā)環(huán)境,設(shè)計出該模塊總體架構(gòu)圖,與其他模塊間交互的關(guān)系。 其次,重點描述作者在項目中所參與部分的開發(fā)內(nèi)容。這包括EVB功能使能的開發(fā),以及S通道的實現(xiàn)。EVB使能的開發(fā)需要涉及到基礎(chǔ)模塊初始化和本地行為初始化,各個子模塊初始化完成后,通過系統(tǒng)提供的不同類型的套接字來完成通信,并且可以將套接字加入epoll中,利用epoll來實現(xiàn)多路復(fù)用的功能。當(dāng)EVB進(jìn)程收到配置消息后,解析EVB TLV,將配置下發(fā)到物理口的配置數(shù)據(jù)結(jié)構(gòu)中。完成了EVB功能使能之后,需要創(chuàng)建S通道。創(chuàng)建之前,為了防止錯誤發(fā)生,配置方式需要檢查創(chuàng)建條件；CDCP協(xié)商則設(shè)計了三條鏈表的算法。S通道創(chuàng)建過程中,本模塊需要和接口管理以及驅(qū)動建立聯(lián)系,幾方共同交互最終實現(xiàn)功能。 最后,對于所開發(fā)的功能給予測試,驗證本設(shè)計的成果。
[Abstract]:With the advent of big data's time, data centers have become more and more relevant to people's lives. One of the iconic technologies of data centers is virtualization, in which multiple virtual machines are installed on one physical server at the same time. Using this technology can greatly improve the efficiency of the server. But the data on the server will eventually be transferred to everyone's hands, so it will use network communication equipment, which is often referred to as the switch. How to forward, control and monitor the data flowing between these virtual machines and switches is the reason of EVBU 802.1Qbg. protocol. Based on the EVB protocol, this paper realizes the main contents of the switch based on the project of a network communication company. The ultimate goal is to realize the information exchange between the virtual machine and the switch. That is, the establishment of the S-channel in this paper means that in order to isolate the channels of each switching entity on the same physical interface between the virtual machine and the switch, the S-Vlan component technology of port mapping is used. A plurality of virtual channels that separate a physical interface. Firstly, the related background knowledge is introduced and combined with the actual hardware and software development environment, the overall architecture diagram of the module is designed, and the relationship between the module and other modules is designed. Secondly, the author's participation in the development of the project is described, which includes the development of the EVB functional enabling, and the development of the S-channel implementation .EVB.The development needs to involve the initialization of the basic module and the initialization of the local behavior. After each sub-module is initialized, the communication is accomplished by the different types of sockets provided by the system, and the socket can be added to the epoll, and the function of multiplexing can be realized by using epoll. When the EVB process receives the configuration message, Parse the EVB tv to send the configuration to the configuration data structure of the physical port. After completing the EVB functionality, you need to create the S channel. In the process of constructing three linked lists, the module needs to establish the connection with the interface management and driver, and finally realizes the function through the interaction of several parties. Finally, the developed functions are tested to verify the results of the design.
