Workshop Dates: February 23 (Monday) - 27 (Friday) 2026
Place: SDSC Auditorium, San Diego Supercomputer Center, UCSD Campus, La Jolla, CA
Workshop Overview
The first meeting in 2026, we will continue our in-person community AIMS workshops to enable researchers and operators to discuss the current state and future directions of active Internet measurement, including the growing role of AI and machine learning in data analysis, infrastructure operation, and training. The purpose of the AIMS-19 workshop will be to discuss:
- Recent design and implementation choices across Internet measurement, data, and cybertraining infrastructure
- Experiences deploying and operating Internet measurement infrastructure across different scales and contexts, including education and training environments
- Metadata practices and data provenance supporting data sharing, reuse, downstream analysis, and responsible AI/ML use
- Community resources, interfaces, and approaches to engagement, including training-oriented platforms and materials
Topics are anything related to Internet measurement.
The AIMS-19 workshop is by invite only.
Register
Registration for AIMS-19 is open. This time, we will not be organizing a hackathon before the workshop, but we this year we will conduct optional advanced topic tutorials/breakout sections midweek.
Tentative Agenda
The workshop will begin at 9:00am Pacific time every day unless noted otherwise.
The posted agenda on the website is tentative. Registered attendees are encouraged to refer to the internally shared active workshop agenda, and monitor the private Mattermost backchannel for updates.
We have plans to hold an Ark, Internet Yellow Pages (IYP), Telescope, and 100GB trace analysis tutorial during the event, but timing is not set yet.

Limited Travel Support
Travel support grants are available for full-time students registered for the workshop in the form of travel (airfare) reimbursement. Preference will be given to those presenting at the meeting.
To apply for a travel grant, two separate email submissions are required: one from the student applicant and one from the advisor.
Materials Submitted by the Student Applicant
The student applicant must email the following materials to with the subject line “AIMS-19 Travel Grant Request”:
-
Curriculum Vitae (CV) of the student applicant.
-
Application Letter, which should include:
- A brief summary of the student’s research interests and accomplishments to date.
- A statement explaining why attendance at AIMS is important to the student.
- An estimate of the costs of attending AIMS, limited to airfare only. Participants are responsible for local transportation and meals; meals will be provided during the event. Travel grants are expected to partially cover airfare costs.
- A statement indicating whether the student has registered for the meeting and whether they have proposed to present a paper, poster, or other contribution as part of the registration process.
Materials Submitted by the Advisor
- Advisor Recommendation Letter (submitted separately).
The advisor must email a brief confirmation note directly to . A formal letter is not required; a short email is sufficient, provided it includes the following information:
- Confirmation that the student is a bona fide Ph.D. candidate or an M.Sc./B.Sc. student in good academic standing at the stated institution.
- A brief statement describing how the student would benefit from attending AIMS.
- A statement of financial commitment indicating that the advisor or institution will cover any remaining travel costs not covered by the grant.
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.
This workshop is being held in the SDSC Auditorium (San Diego Supercomputer Center main building, ground floor).
Directions to SDSC Auditorium Arrive from Hopkins Drive, walk up toward outdoor staircase at the East Entrance, but do not go up. The auditorium is located on the street level floor of the building, to the left of those stairs.
Check the following websites for direction to SDSC:
Taxis, Rideshare, 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. Set your destination to “9836 Hopkins Drive, La Jolla, CA 92093”
Shuttle: Shuttle service between San Diego airport, your hotel, and UCSD can be requested from SuperShuttle San Diego SAN Airport (Cloud 9 Shuttle). Yellow Cab of San Diego. Please consult their websites to find the current fares and conditions. Complimentary shuttle service from hotel to UCSD/SDSC is also available from certain La Jolla hotels.
Trolley and Bus: Lower cost alternatives to UCSD are available via the San Diego Metropolitan Transit System (MTS) buses and the trolley. Consult the Online Transit Information System Trip Planner for customized route options. Please be advised that the punctuality of the buses cannot be guaranteed due to lateness and delays. The nearest trolley station is the UCSD Central Campus Station on the Blue Line Trolley. In both the case of trolley and bus, a short 15-20 minute walk is required to reach SDSC. Consult trolley map and schedules and bus map and schedules for general details.
Driving onto campus: Driving your car onto campus is not recommended because of the scarcity of visitor parking spaces and the high price of parking for the day. If you do drive in by car, 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. Parking legally is the attendee’s responsibility. With a permit purchased on the ParkMobile app (Zone 4752) or a kiosk-purchased parking permit, you can park in any White “ V ” Visitor spaces only, unless otherwise indicated. Visitor 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). Visitor Parking permits are currently $36 per day. The penalty for an improperly parked car is at least $80 per day. We cannot be held responsible for citations issued for parking in an incorrect space or improperly purchased permit, and the appeal process is very time consuming. UCSD Transportation and Parking Services has information about on-campus parking.
