AIMS 2019: Workshop on Active Internet Measurements

CAIDA hosts annual Active Internet Measurement Systems (AIMS) workshops to promote discussion between academics, industry, policymakers, and funding agencies on active Internet measurement, exchange of research ideas and questions that have been answered, or could be answered, with proposed measurement infrastructures.

On April 16 and 17, CAIDA will host the 11th workshop on Active Internet Measurements (AIMS 2019) on the UC San Diego campus in La Jolla, CA.

AIMS 2019 is by invitation only. We are imposing a limit on the number of registrants and will close the registration when we have reached capacity.

Registration closed. We have received an overwhelming response of invited registrants interested in attending, but as seats are limited, we have reached capacity and are no longer accepting new registrations.

Dates: April 16 (Tue) - April 17 (Wed), 2019
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.


All participants are expected to prepare a talk or presentation. Please submit an extended abstract related to one of the topics below with your registration, no later than March 8. We will evaluate the abstracts and notify the authors about acceptance by March 18. Accepted abstracts will be posted publicly on the workshop page.

This year we will not limit talks to active measurements, e.g., I am interested in exploring with folks what can be done with passive measurements from the home to help inform questions like "how much traffic goes further than one AS hop away?", and "what measurements should be sustained over time for research and informing-policy purposes?". Other topics of interest for the agenda include (but are not limited to) the following:

  • Measurements that can address current or future public policy needs
    • how to have impact in broader, non-technical communities (is new conference needed?)
    • how to make technical results for relevant and accessible
    • surveys of which studies have already had impact
    • CAIDA's new PANDA project proposal
    • how to measure progress toward societal aspirations for the Internet
  • Different aspects of "geography" of the ecosystem
    • Where are things, at every level?
    • Includes mapping of country connectivity
    • New methods or new approaches to cross-leveraging existing methods.
  • Infrastructure sharing
    • complementary measurements on different platforms
    • unified interface to traceroute platforms
    • incentives to participate in measurement infrastructure
    • cross-validation of results
  • Infrastructure development issues
    • back-end databases to store measurement results
    • front-end querying interfaces
    • "measurement-as-a-service" support
    • ability to develop and run custom experiments
  • Data access and sharing
    • how applications can make use of measurement data
    • concurrent measurements of interesting events
    • cross-platform longitudinal data analysis
    • educational use of measurements and data
  • Future measurement infrastructure architectures
    • resolving tensions between openness and security of measurement platforms
    • the role of measurement in a larger framework for ISP information disclosure
  • Innovation in scientific discourse to promote reproducibility
    • Presentations of lab notebooks, e.g., Jupyter, as a mode of publishing paper supplements
    • Proposed workshops that require all papers published with "lab notebook" supplements and code required to reproduce the work
    • Peer-review: public vs private; anonymous vs unanonymous reviews; rating systems

Additionally, we intend to devote some time to reviewing the recommendations distilled from the discussions at the previous ten AIMS workshops (2009-2018). These recommendations (published in 2016's AIMS workshop report) deal with the following five common themes:

  1. Data and infrastructure building blocks
  2. Promoting synergies among industry, government, researchers, vendors, Internet service providers
  3. Path measurement research
  4. Quality of experience measurement research
  5. Network architecture research

We will look back to assess the measurable progress achieved in each area and will propose the next steps forward continuing the advancement of Internet measurements.

The workshop will run for 2 days this year (starting from Tuesday morning) with ample time for interactions between participants, breakout sessions, and collaborative discussions.


Participants will have 10-15 minutes to present and 5-10 minutes for questions. To prepare other participants for your presentation, and to maximize discussion rather than presentation time, 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

  • 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.

    • Shuttle to Hotels: SuperShuttle can be arranged to shuttle to UC San Diego campus or your hotel.
    • Taxis and drop-off: San Diego Taxi Information maintains a list of taxis with rates and additional information. Uber and Lyft are also well established in San Diego and now have access to service San Diego's airport. GPSes will need to go to the intersection of Hopkins Drive and Voigt Lane.

      9836 Hopkins Drive , La Jolla, CA 92093 is the nearest street address most GPSes/maps recognize.

    • Car: Rental available at the airport near the baggage claim areas of Terminals 1 and 2.
    • 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 8am-9am, temporarily park at the curb alongside the trees in front of the SDSC building on Hopkins Drive (see Drop off/Loading Zone). If there is a CAIDA staff member there, tell them that you are here for AIMS, and we will give you a special one-day parking permit, and then point you to the Hopkins Parking Structure for parking. If no one is there, park briefly and run into the Auditorium to get a permit first. Otherwise, parking permits are sold at the permit machines by the southwest elevators in the structure for $30/day.

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

      Parking legally is the attendee's responsibility. With a kiosk-purchased parking permit, you can park in any White " V ", Yellow " S " only, unless otherwise indicated. (New for 2019: purchased permits are no longer valid in green "B" spaces.) Please be sure to read the directions on the parking permit. Parking is limited, especially if arriving after 8am (if Hopkins is full, Pangea Parking Structure is the nearest parking alternative within walking distance to SDSC). The penalty for an improperly parked car is at least $65 per day. We cannot be held responsible for citations issued for parking in an incorrect space or improperly displaying your permit.

    For transportation concerns, general questions and help before the workshop, contact Julius Eshabarr at <julius at>.

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