http://www.caida.org/ Recent announcements, publications, and web updates from the Cooperative Association for Internet Data Analysis (CAIDA). What's New http://www.caida.org/data/active/ipv6_aslinks_dataset.xml Wed, 22 May 2013 00:00:00 GMT This dataset is useful for studying the topology of the Internet at the level of Autonomous Systems (ASes), which are approximately network(s) under a single administrative control. ASes are an important abstraction because they are the "unit of routing policy" in the routing system of the global Internet. ASes peer with each other to exchange traffic, and these peering relationships define the high-level global Internet topology. For the purposes of analysis, these peering relationships are represented with an AS graph, where nodes represent ASes and links represent peering relationships. The IPv6 Routed AS Links dataset provides regular snapshots of AS links derived from the ongoing traceroute-like IP-level topology measurements that make up our IPv6 Topology Dataset. We have collected this IP-level IPv6 topology data since December 2008 using our next generation Archipelago (Ark) measurement infrastructure.

The data has been preprocessed with the Corsaro Software Suite. The data is split into files that each contain one hour of data. For each hour we provide one file with flow information in the Corsaro FlowTuple format, and one file containing the source type analysis in the Corsaro Smee format. Note that the corresponding FlowType and Smee Corsaro plugins are required to read the files. The total size of this dataset is 2.1 TB. The destination network addresses have been masked by zeroing the first eight bits of the IP address. Source addresses have been anonymized using Cryptopan anonymization with a single key.

The first day (21 November 2008) covers the onset of the Conficker A infection [5, 6]. On the second day, 21 December 2008, only Conficker A was active; and during the third and final day both Conficker A and B were active. Please, note that these are "raw" traces: no attempt has been made to identify or filter any packets as specifically Conficker-related. This dataset contains 68 compressed pcap files each containing one hour of traces. The total size of the dataset is 69 GB (16, 19 and 34 GB for each of the three days). The pcap files only contain packet headers; payload has been removed. The destination network addresses have been masked by zeroing the first eight bits of the IP address.

The workshop was originally scheduled for September 23-24th but due to various logistics and availability of participants, the decision has been made to conduct the workshop wholly by web videoconference. The goal of this workshop is to bring together researchers, commercial Internet facilities and service providers, technologists, theorists, policy makers, RIR stakeholders, and pundits of Internet economics to try to frame a concrete and useful research agenda for the emerging but stunted field of Internet infrastructure economics. Slidesets from the workshop are made available for viewing.

What's New http://www.caida.org/research/traffic-analysis/tcpudpratio/ Mon, 18 May 2009 00:00:00 GMT It is still an accepted assumption that most Internet traffic is transmitted via the TCP protocol. However, the rise of new streaming applications and P2P protocols that try to avoid traffic shaping techniques will likely increase the use of UDP as a transport protocol. We evaluate the amount of UDP and TCP traffic, in terms of flows, packets and bytes, on traces collected in the period 2002-2009 on several backbone links located in the US and Sweden. Our initial analysis suggests: In these observations, we found that most UDP flows use random high ports and carry few packets with little content, consistent with its use as a signaling protocol for increasingly popular P2P applications.

The focus of this measurement is on discovering topology and not on finding responding destinations. A globally distributed set of Archipelago (Ark) monitors has continuously collected this data since December 12, 2008.

What's New http://www.caida.org/research/security/ms08-067/conficker.xml Fri, 6 Mar 2009 00:00:00 GMT On October 23, 2008, Microsoft announced a security update that resolved a critical vulnerability in the Windows Server service (MS08-067). In this bulletin, Microsoft stated, "it is possible that this vulnerability could be used in the crafting of a wormable exploit". While various rumors spread, the first serious evidence of a worm outbreak was reported on November 22 2008 by PC World. Security researchers and companies have given this worm various names including Downadup, Conficker, Conflicker and Kido. A preliminary analysis of the worm follows. Because this event is still in progress and the data includes sensitive information, we cannot publicly disclose all the information we have at this point. What's New http://www.caida.org/workshops/isma/0902/ Thu, 12 Feb 2009 00:00:00 GMT On February 12-13, 2009, CAIDA will host a workshop on Active Internet Measurements supporting science and policy (by invitation only) in La Jolla, CA. This workshop continues the series of Internet Statistics and Metrics Analysis (ISMA) workshops that are held to discuss the current and future state of Internet measurement and analysis. This workshop will seek to define priority directions of various active measurement infrastructures especially aimed at macroscopic security, stability, and performance measurements. Feb 12-13 What's New http://www.caida.org/research/traffic-analysis/asymmetry/ Tue, 10 Feb 2009 00:00:00 GMT Many people assume symmetry in traffic on Internet links, that is, they assume that they see both directions of a conversation flow across the same physical link. Below we describe data collected on three different types of Internet infrastructure that we believe sheds some light on this myth. According to our best available data, traffic symmetry typically does not hold for network locations beyond intranet and access links. We also propose a normalized measure of traffic symmetry which excludes traffic that is asymmetric by definition, such as UDP, ICMP and TCP background radiation. What's New http://www.caida.org/research/traffic-analysis/classification-overview/ Tue, 10 Feb 2009 00:00:00 GMT Internet traffic classification gains continuous attention while many applications emerge on the Internet with obfuscation techniques. Related papers tend to try to classify whatever traffic samples a researcher can find, with no systematic integration of results. To fill this gap, we have created a structured taxonomy of traffic classification papers and their data sets. Furthermore, we hope to reveal issues and challenges in traffic classification.

Nov 3-4 What's New http://blog.caida.org/ Wed, 1 Nov 2006 00:00:00 GMT In less than two decades the Internet evolved from academic testbed to critical civil infrastructure. Objective analyses of the most rigorous and relevant empirical measurements are essential to enlightened policy, secure commerce, and public confidence. There is an alarming and growing gap between questions the Internet science, technology, and policy communities ask and what the Internet research community can answer. This blog is an experiment in discussing current Internet measurement and data-related issues in a format less formal than CAIDA's research paper publications. We plan to highlight issues that are starving for empirical grounding, to invite others to share measurements that inform a specific issue, and to narrow the gap between current debates and the best available data.

Tools http://www.caida.org/tools/taxonomy/anonymization.xml Mon, 22 Dec 2008 00:00:00 GMT Researchers studying the Internet face a significant challenge in looking for traffic traces: the fundamental conflict between end-user privacy and the research utility of data. When data is heavily anonymized, important attributes of data that reveal the structure and function of networks are obscured. If data is not heavily anonymized, details about end users, including geographic and network location, organization, names, passwords, and other personal information could be subject to unauthorized access. We provide the following list of anonymization tools to help those searching for such tools to find them and also better understand and track availability of such methods.
