AIMS 2015: Workshop on Active Internet Measurements

For the last 6 years CAIDA has hosted the "Active Internet Measurement Systems" workshops, to promote discussion between academics, industry, policymakers, and funding agencies on active Internet measurement, and exchange of research ideas and questions that have been answered, or could be answered with existing or proposed measurement infrastructures.

From March 31 to April 2, 2015, CAIDA hosted the 7th workshop on Active Internet Measurements (AIMS 2015) supporting science and policy.

AIMS 2015 is by invitation only. Registration is closed.

Dates: March 31 (Tue) - April 2 (Thu), 2015
Place: Auditorium B210E/B211E Meeting Room,
San Diego Supercomputer Center, UC San Diego Campus, La Jolla, CA

For information on Local Arrangements / Getting to UC San Diego, see the bottom of this document.


We would like to structure this workshop around how the Archipelago Measurement Infrastructure (Ark) can (or is) supporting studies of Internet security and stability, vulnerabilities, scientific topology modeling and mapping, Internet architecture and evolution, and others. This workshop will serve as a forum for a researchers to provide feedback on what measurements, capabilities, data formats, and curation functionalities would be most helpful to answer specific research questions. We can then customize and enhance Ark measurements, data curation, and the query interface to support study of those questions.

Key topics to be discussed include:

  • Increased deployment
    • additional visibility of network edge
    • improved AS-level graph
    • diagnostic measurements of DNS root and top-level
    • domain services
    • systematic comparison of traceroute & BGP paths augment Bismark
    • quantifying the presence of MPLS tunnels
    • network fingerprinting based on router signatures
  • Measurements on-demand
    • expanded flexibility to run custom experiments
    • analyze causes of large-scale BGP routing events
    • targeted measurements for BGP hijacks
    • developing user-defined measurement functionality
    • support Reverse traceroutes
    • close to real time alias resolution measurements
  • IPv4/IPv6 transition
    • studying middleboxes
    • IPv6 deployment
    • tools for detection & performance assessment of CGN
  • Censorship/outages
    • circumvention techniques
    • censorship studies
    • monitoring for outages
  • CongestionA sequence of commands recorded to a register (this tip).
    • use ITDK and MIDAR for congestion studies
  • Geolocation
    • study of geographic paths
    • improved geolocation of core router infrastructure
  • Tools
    • deploy CAIDA measurement tools on Bismark
    • add Reverse traceroutes to scamper
    • Python API, ability to run TCP-HICCUPS, real-time
    • monitor availability status
  • Using curated data sets (discuss what curations are desired)
  • Educational use
    • easy access, visualization
    • hands-on experimentation
    • web interface, simplified data products
    • studying network protocols
  • Specific studies/needs
    • security incidents in misconfigured networks (spoofer)
    • IPv6 topology discovery geolocation
    • network availability measurements
    • spoofer
    • high-frequency topology characterization
    • tracking IPv4 to IPv6 transition
    • investigating the accuracy of routing models studying IXPs interconnectivity


To generate discussion and to orient other participants to your talk, please send a URL or a PDF to of something you'd like the audience to have read before your talk. This can be any of:

  • a related URL that inspires your research
  • a related URL detailing your research
  • a URL related to your talk that you consider worth other participants' time to look over
  • a recent blog entry or article so people can get an idea of who you are
  • the actual PDF slideset which you'll be presenting

March 31 (Tuesday)

Local Arrangements / Getting to UC San Diego

For this workshop, attendees are expected to make their own hotel reservations and transportation arrangements from their hotels to the workshop. For CAIDA's list of local hotels including shuttle availability, see the updated Local Hotels list (PDF). Contact the hotel directly for hotel shuttle schedules (if available) to the San Diego Supercomputer Center (SDSC).

This workshop is being held in the SDSC East Auditorium (Room B210E/B211E) that faces Hopkins Drive.
(For those GPS-enabled attendees, the GPS coordinates near the SDSC Auditorium is WGS84: 32°53'03.77"N, 117°14'20.31"W)

General driving directions to SDSC are located on the CAIDA Contact and Visitor Info page.

  • Parking on campus
    The most convenient parking is in the Hopkins parking structure at Hopkins Dr and Voigt Dr, just south of SDSC.

    Parking Permits: Parking permits are required to park on UC San Diego Campus. On arrival to campus on the morning of Day 1 from 8:00-9:00 before the workshop starts, check in with a CAIDA staff member at the driveway loop in front of the SDSC building on Hopkins Drive. We will give you a parking permit for the day, and then point you to the Hopkins Parking Structure for parking. For late arrivals, parking permits are sold at the kiosks in the structure for $16/day.

    Parking permits for subsequent days will be provided at the end of Day 1, just prior to the Reception.

    After picking up your parking permit, it is recommended you go to the Hopkins Parking Structure next to SDSC and park on the lower levels. Walk back to the street-side of the parking garage (level 2), and along the street to the SDSC East building. The auditorium is on the left just before the stairs, labeled Auditorium or B210E/B211E Meeting Room.

The AIMS 2015 workshop will be held in the SDSC Auditorium.

For transportation concerns, general questions and help before the workshop, contact Cindy Wong at <cindy at>.

General UC San Diego Maps and general UC San Diego Visitor Parking information are useful resources for navigating on campus.


Funding for this event is provided by the National Science Foundation and the U.S. Department of Homeland Security Science and Technology Directorate.
