发布时间：2018-08-07 11:17
【摘要】：随着互联网的发展与普及,网络早已经成为了当代人们生活、工作和娱乐学习等各个方面的基础支持之一。然而,现有的网络架构已经越来越难以满足个人、企业及运营商的需求。OpenFlow,这种集中式网络体系架构顺应时代的需求逐渐得到了发展。在这种新型网络体系架构下,云计算,网络虚拟化等等技术也有了快速的发展。本文基于OpenDayLight开源控制器,以网络虚拟化为目标,利用OpenFlow网络控制器集中控制网络的特性,统一管理底层物理网络,进行网络虚拟化,为上层业务控制器提供一个虚拟的网络环境。为了更好地提供网络虚拟化服务,本文通过读取数据库配置来动态分配虚拟网络资源,模拟交换机连接为上层的业务控制器提供了标准的OpenFlow协议接口,下发初始流表至底层交换机对数据平面的流量进行隔离。处理交换机与控制器之间的控制消息,完成对网络资源的隔离。然后,本文详细描述了支持多协议虚拟网络控制管理组件的设计与实现,主要包括虚拟化控制器与扩展交换机接口,虚拟网络配置管理,控制消息的处理,多协议配置与网络管理可视化接口等。最后,论文给出了一系列的系统测试方案和测试结果分析,对多协议解析功能、虚拟网络资源隔离以及虚拟网络业务支持功能进行了验证。
[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.
