ACM Statement

In the United States, and throughout many regions around the world, current events have brought attention to the urgent need for equality and respect for all individuals. ACM reaffirms its commitment to fostering diversity and inclusion within the global computer science community.  

As an international organization of nearly 100,000 professionals, ACM respects the essential worth of all people and firmly believes that diversity strengthens the scientific enterprise and society as a whole. ACM’s Code of Professional Ethics embodies these principles, and our Diversity and Inclusion Council works to translate them into effective action. 

ACM is committed to creating an environment that welcomes new ideas and perspectives, and where hostility or other harmful behaviors are not tolerated. As an organization, we stand with those who promote inclusivity.


SIGCOMM is ACM's professional forum for discussing communications and computer networks.

SIGCOMM members include scientists, engineers, educators and students. They study all aspects of computer communications and networks: analysis, technical design, engineering, measurement and management. Our members are particularly interested in the systems engineering and architectural questions surrounding computer communication.

Special Statement on Freedom of Mobility

    As availability of vaccines begins to change the COVID-19 situation, the SIGCOMM Executive Committee is exploring how it can best support events with some return to in-person activities. To help us plan for the next few years in a way that best supports the community, it would be very helpful to us if you can fill out this survey:

    The organizing committee is delighted to invite you all to ACM SIGCOMM 2021, the flagship annual conference of the ACM Special Interest Group on Data Communication. We are excited to announce that the SIGCOMM main program will for the first time extend over four, instead of three, days, bringing an extra day of learning, networking, discussion, and more! Our main program includes 55 full-length papers, a keynote talk by the SIGCOMM Award winner, Hari Balakrishnan; the announcement of the SIGCOMM Test-of-Time Award; a best of CCR session; a Student Research Competition; and two poster sessions with 21 posters and 9 demos. Furthermore, the main program is complemented by eight workshops, six tutorials, and three hackathons. And we will be providing a mentoring program to assist junior researchers, dedicated slots to meet our sponsors, as well as various other social and mentoring events towards making this a vibrant, interactive conference. Thanks to our sponsors, we are able to provide an aggressive fee waiver program that we hope can enable all to attend. To register, please visit:

    With increased access to vaccination, relaxation of local travel and gathering restrictions are quite possible in certain regions. In support of a return to in-person activities, SIGCOMM'21 is calling for creation of "watch parties" and "pods" to allow small groups to meet where it is safe to do so. To propose a pod, or to see how to join a pod near you, please visit:


    SIGCOMM CARES Recommendations document in response to HotNets incident (December 2020)
    In September 2020, the SIGCOMM CARES committee was made aware of a situation that arose in the HotNets 2020 review process. SIGCOMM CARES received two complaints, one sent by all three authors and one from the lead author alone. The incident was discussed in the committee and multiple parties involved were consulted, leading to a list of 7 recommendations. The implementation of these recommendations by the different actors responsible for overseeing the review process, namely ACM, SIGCOMM and Conference Steering Committees, PC chairs, PC committees and the CARES Committee, will hopefully help prevent similar incidents in the future. 


    SIGCOMM CARES Community Meetings
    CARES planned two community meetings in April 2021 to communicate and clarify its role. These meetings are intended to serve as both sessions on CARES and a means to foster discussion on how CARES and ACM might evolve to better serve the community as well as a forum to answer questions that community members may have.
    1st Meeting -- Friday, April 2, from 2pm ET

    2nd Meeting -- Friday, April 23, at 9am ET


    Being a student volunteer is a great opportunity to get plugged into the community -- meet the organizing committee and attendees, and learn how to run a conference! Opportunities will include stimulating discussions on the slack, monitoring the conference, helping to report problems, running platforms, helping us brainstorm, and more! No experience needed (we will teach you what you need to know!). To sign up, please email a resume and brief description of your interests to sigcomm21.chairs@gmail.com with "[SIGCOMM - Volunteer]" in the subject line.

    Au Revoir from the current EC
    It’s hard to imagine, but it has now been 4 years since this EC started its term.  I can vividly recall my trepidations before the opening session of SIGCOMM 2017 in LA that marked my first participation as SIGCOMM chair, and I must say that if I had had a crystal ball, those trepidations might have morphed into sheer panic. Obviously, none of us could have foretold COVID-19 and how much havoc it would wreck, and my thoughts go to all those who have been affected and those who continue to be.  On the SIG front, the main impact was the need to switch to virtual events.  SIGCOMM 2020 had to pivot late in its planning process from being held at Columbia in NYC to being the first to experiment with a fully virtual format. I’m forever grateful to Henning, Vishal, and their team for stepping-up to a task they had not really signed-up for.  However, looking back as well as ahead, the SIG has weathered the transition relatively well.  We have not taken anywhere near the kind of financial hit we might have expected, with most of our conferences remaining in the black.  More importantly, we have also learned useful lessons on how to leverage our experience with virtual events.  Even if the departing EC pledged an in-person reunion at SIGCOMM 2022, it also acknowledged the positive aspects of virtual participation.  There is no denying that virtual conferences have made it possible for many more to attend who, no matter how many travel grants we can provide, would otherwise have been unable to attend our events.  As a result, going forward, we have pledged to continue to offer the possibility of remote participation even after we are back to having in-person conferences.
    The impact of COVID-19 has, however, also been felt indirectly in the many things we ended-up either not doing or not doing as much as planned.  One of my goals when starting as chair had been to increase the diversity of our SIG, and while we have made some progress, there is no denying that much, much more remains to be done.  Nevertheless, a few positive steps were taken, including standing-up a CARES committee, which even if its mandate is still evolving, has provided a renewed focus as well as resources that SIG members can tap into.  We also relaunched our efforts to increase participation from South America with a student-focused workshop that successfully started in 2019.  It was to be reprieved in 2020, but had to be put on hold because of COVID-19, and 2021 remains uncertain. I very much hope that we can restart it soon and tap into the enthusiasm that permeated the first edition.
    Let me end this already too long “closing statement” by thanking all past and present members of the EC with whom I have had the pleasure to serve.  One of the things that serving as SIGCOMM chair has made me acutely aware of is the amount of time and energy that all our volunteers are willing to invest in the SIG and its events, and EC members are very much on the frontline with often very little visibility and recognition for their efforts from the rest of our community.  I am truly grateful for their dedication and for sticking through the ups and downs of the past four years.  Last but not least, I also want to welcome the incoming EC.  The SIG is in great hands and I wish them the best of luck in taking the SIG forward into a (hopefully) post-COVID world.
    Roch Guerin, departing SIG chair
