【摘要】：隨著網(wǎng)絡信息量的不斷膨脹,數(shù)據(jù)中心作為信息處理的設施,正發(fā)揮著不可替代的作用。而傳統(tǒng)數(shù)據(jù)中心下的服務器已暴露出資源利用率低的缺點。與傳統(tǒng)數(shù)據(jù)中心相比,云計算環(huán)境下推出的數(shù)據(jù)中心順應時代的發(fā)展,采用虛擬化技術來提高服務器資源的利用率。通過虛擬化技術,服務器內(nèi)部虛擬出多個虛擬機,這些虛擬機之間需要交互信息。解決虛擬機間通信的技術主要包括傳統(tǒng)的虛擬交換機VEB(Virtual Ethernet Bridge)模式和虛擬以太網(wǎng)端口匯聚VEPA(Virtual Ethernet Port Aggregator)模式。VEB模式在服務器內(nèi)部引入虛擬交換機來完成虛擬機間信息交互的工作,而VEPA模式的提出旨在減輕服務器的工作負擔,解決服務器與網(wǎng)絡之間管理邊界模糊的問題,同時達到網(wǎng)絡管理系統(tǒng)統(tǒng)一部署網(wǎng)絡的目的。 本論文研究的虛擬機間通信技術主要是在杭州華三通信技術有限公司(簡稱H3C)的EVB(Edge Virtual Bridging,邊緣虛擬網(wǎng)橋)開發(fā)項目上進行的。根據(jù)IEEE提出的802.1Qbg標準體系,EVB的實現(xiàn)采用VEPA模式,對與服務器相連的外部交換機設備進行改進,將虛擬機接口映射到交換機端口上,即在服務器與交換機之間建立虛擬通道,使得虛擬機間的通信數(shù)據(jù)經(jīng)由虛擬通道轉(zhuǎn)發(fā)。本文作者參與了EVB項目的整個研發(fā)過程,包括需求分析、概要設計、詳細設計、代碼編寫、單元測試和系統(tǒng)測試各個環(huán)節(jié)。 本文主要內(nèi)容是,在IEEE802.1Qbg EVB技術標準下研究HXC-EVB虛擬化系統(tǒng),對接入交換機進行虛擬化設計,實現(xiàn)服務器與交換機之間連接通道的建立。本文的主要工作包括如下幾方面： 1、研究兩種虛擬機間的通信方式,即VEB模式和VEPA模式。通過對比得出EVB虛擬化技術基于的VEPA模式的優(yōu)勢。 2、研究HXC-EVB虛擬化系統(tǒng)的框架結構,結合協(xié)議需求提出虛擬通道的實現(xiàn)方案。在Comware軟件開發(fā)平臺中,對EVB功能進行模塊化設計,主要分為EVB內(nèi)核模塊、EVB守護進程模塊、EVB命令行管理插件和管理對象庫模塊四部分,并在系統(tǒng)中其他基礎模塊的配合下完成配置處理和協(xié)議報文收發(fā)處理。并且,就如何實現(xiàn)HXC-EVB虛擬化系統(tǒng)中的通信機制進行闡述。通信情況包括進程間的通信和各物理板間的通信,使用套接字Socket支持的LIPC協(xié)議族和epoll多路復用技術實現(xiàn)進程間的通信,使用mesh組件函數(shù)實現(xiàn)板間的通信。 3、對HXC-EVB虛擬化系統(tǒng)實現(xiàn)的特性功能進行系統(tǒng)測試,驗證服務器與交換機之間連接通道的實現(xiàn)。主要包括命令行和協(xié)議報文創(chuàng)建虛擬通道、虛擬通道對協(xié)議報文的收發(fā)情況及有關策略控制的流量測試,并對測試結果進行分析和總結。
[Abstract]:With the expansion of network information, data center is playing an irreplaceable role as an information processing facility.
