研究概况

1. 基于形式化方法的互联网协议测试研究:提出了一种多组件并行有限状态机模型及其协议测试生成技术,为协议测试提供了坚实的基础;基于形式化测试语言TTCN的系列标准,作为总体设计负责人之一,设计实现了跨协议、跨平台的分布式通用协议集成测试系统PITSv3,通过扩展TTCN语法和语义,解决了低成本、高效率支持新型网络协议和技术测试的难题。基于上述模型方法和系统,主持研发了SAVI(接入网源地址验证)和SDN(软件定义网络)等新型网络协议和技术的测试集,高效支持了这些新型网络技术的测试。为网络运营商和科研单位提供了大量测试服务,获得了2016年中国电子学会技术发明一等奖(排名2/6)等奖励。

2. 互联网路由和流量的异常检测研究:在互联网域间路由前缀劫持检测方面,针对传统域间路由劫持检测准确度低、延迟大、扩展性差的问题,提出了一种基于控制平面和数据平面相关性的路由指纹模型及路由前缀劫持动态检测方法,显著提升了前缀劫持监测的准确度、覆盖率和实时性;实现了国际上首个公开发布监测报告的全球互联网前缀劫持在线监测平台Argus,为保障全球互联网域间路由安全提供了重要的技术支撑,已经成为国内外网络运营商重要的安全态势参考,相关论文获得国际互联网测量会议IMC颁发的首个Community Contribution Award,根据Google scholar统计单篇引用次数已达70余次。在基于大数据平台的网络流量异常检测方面,为解决对海量和高速网络流量进行异常检测的难题,提出了两种新型的信息熵流量度量特征模型,并提出了基于大数据平台的网络流量异常检测方法和系统。系统已在清华校园网和中国电信进行了部署和试验。

3. 新型互联网路由体系结构和协议研究:在互联网域间和域内多路径路由机制方面,在域间层面,提出了一种基于AS环的不相交多路径路由机制DIMR,并建立了形式化模型从理论上证明了其收敛性;在域内层面,提出了高效的分布式动态多路径路由机制DMPA,并根据路由度量模型证明了其正确性。解决了采用分布式算法如何正确高效的进行多路径路由计算的难题。在混合SDN(软件定义网络)中面向流量工程的路由优化方面,充分结合分布式路由和集中式路由各自的优势,提出了基于单一流量矩阵和多流量矩阵的SDN/IP混合网络下的流量工程路由机制,实现了对网络资源的高效灵活利用。相关研究成果发表在Computer Networks、ICNP等SCI国际期刊和重要国际会议上。
