![]() How to find correlated Internet failures, Passive and Active Measurement Conference (PAM), Mar 2019.IODA-NP: Internet Outage Detection and Analysis, DHS S&T Cybersecurity and Innovation Showcase, Mar 2019.Corsaro enables IODA's processing of IBR captured atĭarknets to provide time series for outage detection and analysis. It was specifically designed to be used with passive traces captured by darknets, but the overall structure is generic enough to be used with any type of passive trace data. It is optimized for writing values for many time series simultaneously.Ĭorsaro is a software suite for performing large-scale analysis of trace data. Libtimeseries is a C library that provides a high-performance abstraction layer for efficiently writing to time series databases. DBATS can easily sustain write speeds of more than 1.6 million values per second, and CAIDA has used DBATS databases with more than 40 million distinct series. BGPStream fills this gap, enabling efficient investigation of events, rapid prototyping, and building complex tools and large-scale monitoring applications (e.g., detection of connectivity disruptions or BGP hijacking attacks).ĭBATS is a high performance time series database engine optimized for inserting/updating values for many series simultaneously. Although BGP is a crucial operational component of the Internet infrastructure, and is the subject of research in the areas of Internet performance, security, topology, protocols, economics, etc., there is no efficient way of processing large amounts of distributed and/or live BGP measurement data. General applicablity to research and applicative fields of networking.īGPStream is an open-source software framework for live and historical BGP data analysis, supporting scientific research, operational monitoring, and post-event analysis. Several of the project's software components offer We released the software components we developed in this project with an CAIDA had several meetings with the FCC to discuss results of the IODA project, providing the FCC with additional insight into the complexity of Internet outage monitoring and to discuss technology transfer of some of these research results and infrastructure capabilities. To accomplish this task, the PSHSB developed a data-driven process centered on collecting information on and performing analyses of communication outages. The Public Safety and Homeland Security Bureau (PSHSB) of the Federal Communications Commission (FCC) has the responsibility for ensuring that communications networks are reliable, resilient and secure. OpenBMP implementation of the BGP Monitoring Protocol. Internal and open source projects carried out by Cisco, such as the We established a collaboration with researchers at Cisco Systems, whoĪre using BGPStream and are collaborating in extending it to support In addition, Comcast, through their Innovation Fund provided a research grant for the development of visual interfaces to monitor and characterize Internet outages. We are collaborating with Comcast researchers, who are using IODA to support their own research on Internet reliability and performance. ![]() Outage events and the corresponding signals obtained through automatedĪnalysis are displayed on dashboards and interactive graphs that allow the Sources, establishes the relevance of an event and generates alerts. Our outage inference system combines information from these three data University of Southern California to infer when a /24 block is affected (routable) IPv4 address space from several CAIDA Ark nodesĭistributed worldwide and use a methodology developed by
