1、 本本 科科 毕毕 业业 设设 计(论文)计(论文) 题题 目:基于目:基于 SDNSDN 的网络带宽保障系统的网络带宽保障系统 流量分析流量分析 学生姓名: 学 号: 专业班级:计算机科学与技术 11-1 班 指导教师: 2015 年 6 月 14 日 基于 SDN 的网络带宽保障系统 流量分析 摘 要 为解决传统网络在发展过程中出现的一系列问题, SDN 技术应运而生。 由于数据中 心数据流量巨大,设备管理复杂,对服务器和虚拟机的快速配置和数据迁移都有较高的 要求,SDN 的应用可以提高数据交换的效率,增加数据中心可控性。但数据中心一般只 尽力转发多种业务,并不为某一业务提供额外的带宽保障
2、。为确保某些关键业务的服务 质量得到保障,需要为其进行带宽预留与保障。 本课题旨在研究通过 SDN 控制器利用 REST API 获取网络信息, 并经过处理转化为 直观的图形用户界面显示。通过流量监控客户端,用户可直接观察全网拓扑和实时的流 量状态,为下达保障策略提供支持。 关键关键词词:SDN;流量监控;带宽保障;图形显示 Network Bandwidth Guarantee System Based on SDN Traffic Analysis Abstract In order to solve a set of problems arising during the process
3、 of the traditional network development, SDN technology emerges as the time requires. As data flows are so overwhelming, devices management could be very complicated, and rapid configurations for servers and virtual machines as well as data transfer are all highly required. The application of SDN ca
4、n improve the efficiency of the data exchange and enhance the controllability of the data center. But generally, data center can only try its best to forward varieties of services, instead of providing additional bandwidth guarantee for a certain one. In order to ensure that the quality of service for some essential businesses can be guaranteed, it needs to reserve bandwidth and guarantee it for them. This thesis is designed to study how to acquire network information through S
