作为全球互联网网络研究前沿机构CAIDA,认真学习该网站前沿内容是非常有意思且有意义的一件事情,从地图基础课题的网络互联关系,到网络拓扑,到国际网络仿真,再到BGP路由安全态势感知。我所涉足的几个方向,CAIDA有着大量的研究案例值得我去学习和借鉴,要学会站在前人的肩膀上继续前行。

从已有的认识来看,CAIDA在网络互联关系,网络拓扑数据的采集和分析方面的工作做得很扎实,从1998年起他们就在积累数据,国内方面在这块的研究相对不足。本着学术开放的精神,CAIDA开放了大量的互联关系数据和网络拓扑数据(当然有些数据亦可通过RIPE和RouteViews的路由采集项目获取),通过研究这些开放的数据集,对于我理解和研究全球互联网网络大有裨益。而国际网络仿真和BGP路由安全,CAIDA官方所公开的一些信息可能并没有研究的太深入,或许是刚起步研究阶段亦或是没有公开。例如“CAIDA 2018-2023 Program Plan”中提到,“We will undertake a new project that studies topological weaknesses from a nation-state security and stability perspective.”CAIDA想要从国家安全和稳定的角度去研究网络拓扑的弱点,和我想要做的国际网络仿真(国家网络的抗毁性)在很大程度上其实是一件事,我希望通过复杂网络理论,去研究全球互联网网络。

I.Measurements and Infrastructure Projects

PANDA& Ark& UCSD Network Telescope& MANIC& IDOA-NP& Spoofer& Passive Traffic Monitors

Develop new visualization tools to allow non-experts to understand various aspects of Internet structure, using geographic and economic annotations on the data, with access controls where appropriate for sensitive data.(将开发新的可视化工具,让非专业人士了解互联网架构的各个方面,使用地理位置和经济数据进行注释,一些敏感数据会限制访问)【PANDA】


integrate user traffic data from home networks with BGP-aware and IXP-aware functionality.(把家庭路由流量数据与BGP感知和IXP感知数据相结合,或许可以碰撞出新的火花)【PANDA】
cross-correlate MANIC results with our AS-relationship data.(将测量数据(Ping/Trace)与AS关系数据结合,即将数据层面和控制层面相结合,很好的思路,用于绘制网络空间)【MANIC】
correlate MANIC results with outage information from various sources (IODA, NANOG, Twitter feeds)(融合多方网络中断信息)【MANIC】

II. Research and Analysis

We seek to characterize fundamental behavior of the Internet as an evolving complex system and predict -- and in some cases design -- salient aspects of future evolution.(CAIDA试着把互联网当成一个不断变化的复杂系统来研究,对其未来的变化进行预测,这与我的认识是一致的)


Internet science has become a fundamentally interdisciplinary endeavor,
requiring consideration of economic, policy, regulatory, and international relations factors.……and start an entirely new one that investigates the susceptibility of the Internet topology to country-level connectivity disruption and manipulation.(互联网科学研究是跨学科的,它需要考虑经济、政策、管理和国际关系等因素。CAIDA正在开始一个全新的研究-互联网拓扑结构对国家级连接中断和控制的敏感性,即用国家的维度去研究互联网拓扑)


Internet cartography is emerging as its own discipline, essential to characterizing this critical infrastructure and understanding its macroscopic properties, dynamic behavior, performance, and evolution.Maps are also crucial for realistic modeling, simulation, and analysis of the Internet and other large-scale complex networks. These maps can be constructed for different layers (or granularities),
e.g., fiber/copper cable, IP address, router, Points-of-Presence (PoPs), autonomous system (AS), ISP/organization.(地图基础课题只是互联网地图绘制的开始而不是终点,任重而道远)



CAIDA has conducted and shared measurements of the Internet macroscopic topology since 1998.(CAIDA可以提供网络拓扑数据)

Our current tools (since 2007, scamper deployed on the Archipelago measurement infrastructure) track global IP level connectivity by sending probe packets from a set of source monitors to millions of geographically distributed destinations across the IPv4 address space.


Since 2008, we have continuously probed IPv6 address space as well.(CAIDA可以提供IPv4/IPv6的主动探测数据,使用scamper工具)


create an AS-traceroute measurement tool that integrates control path and forward path data in real-time.(与我的想法不谋而合,trace不同的AS,trace路径和性能数据)
create informative visualizations of large-scale network topology measurements.(大规模网络拓扑测量的信息可视化,也是我正在做的事)
create software to analyze statistical properties of router-level Internet graphs, including awareness of data idiosyncrasies that prevent standard statistical computations.(分析互联网地图的统计特性)

CAIDA researchers study not only technical, but economic and policy aspects of the Internet, developing measurement tools and modeling methodologies to investigate questions related to infrastructure resiliency, emerging trends, network economics, and public policy.(不仅仅研究网络本身,还会研究经济政策)

Analyzing the susceptibility of the Internet topology to country-level manipulation.(Country-Level是一个大方向,也是大领导所关注的事情)
identify topological vulnerabilities for specific countries/regions.(识别特定国家或地区的拓扑关键节点及其脆弱性)
study the evolution of the topology and topological weaknesses of countries/regions over time.(研究特定国家或地区的拓扑结构及抗毁性随时间的演变)
study methods to detect and characterize BGP hijacking events, including extent, frequency, and impact。(研究监测和描述BGP劫持事件的方法,包括范围、频率和影响)
analyze and validate metrics for use in detecting and characterizing these vulnerabilities.(指标体系)

III. Data Collections

CAIDA is reknown worldwide
as the leader in conducting macroscopic Internet measurements to support scientific research.(CAIDA以互联网宏观数据采集而在世界范围内被领域研究人员知晓)


Scientific data collection, tool development, and analysis are among CAIDA's core objectives.(网络科学数据采集、工具开发以及数据分析是CAIDA的核心目标)

CAIDA data sharing experience and activities enabled us to become one of the founding
and leading members of the Information Marketplace for Policy and Analysis of Cyber-risk & Trust (IMPACT) program founded by the U.S. Department of Homeland Security, Science & Technology Directorate, Cyber Security Division (DHS S&T CCD).(IMPACT项目仅限于五眼联盟及其盟友,中国研究者不能获取相关数据)
