基于OpenDaylight的虛擬網絡QoS控制系統的設計與實現
首發時間:2018-06-12
摘要:隨著網絡規模和網絡流量的爆炸式增長,網絡管理的難度越來越大。在傳統網絡中QoS(Quality of Service,網絡服務質量)由于高復雜度和高開銷,一種直沒有一個很好的實現方案。SDN(Software Defned Network,軟件定義網絡)中控制與轉發分離的特性,給QoS的實現提供了一個非常好的機會。ODL(OpenDaylight)是功能最強大的SDN網絡控制器平臺,VTN(Virtual Tenant Network,虛擬租戶網絡)是基于ODL的虛擬租戶網絡模塊,在物理網絡上為網絡租戶創建安全可靠的虛擬私有網絡。本文利用VTN搭建了一個網絡監督和管理平臺,能夠實時監控網絡的時延和帶寬信息。該平臺修改了ODL 源代碼,添加了時延探測功能,并能夠為網絡中的流量實施不同的選路策略。同時,該平臺還提供了用戶友好的界面和使用方式,用戶能夠通過訪問瀏覽器,簡單地對網絡進行監督和管理。

Design and Implementation of QoS System of Virtual Network in OpenDaylight
Abstract:With the explosive growth of network scale and network traffic, network management is becoming more and more difficult. In traditional networks, QoS (Quality of Service) has not implemented a good solution because of its high complexity and high overhead. The separation of controlling and forwarding in SDN (Software Defined Network) provides a very good opportunity for the realization of QoS. ODL (OpenDaylight) is the most powerful SDN network controller platform. VTN (Virtual Tenant Network) is a virtual tenant network module based on ODL to create a secure and reliable virtual private network for network tenants on a physical network. This paper builds a network monitoring and management platform based on VTN. The platform can monitor network delay and bandwidth information in real time, and can implement different routing strategies for traffic in the network. At the same time, the platform also provides a user-friendly interface. Users can simply access the browser to supervise and manage the network.
