Call For Papers, ACM IMC 2021, Online

The Internet Measurement Conference (IMC) is a highly selective venue for the presentation of measurement-based research in data communications. The focus of IMC 2021 will be on research that improves the practice of network measurement, illuminates some facet of an operational network, or both. We encourage authors to discuss the implications of their results on future research and/or operations. We encourage authors to discuss representativeness and limitations of their work due to coverage of their measurements across space and time. Finally, we encourage authors to validate inferences using ground truth.

IMC takes a broad view of contributions that are considered in scope for improving the practice of network measurement, including, but not limited to:

Networks of interest include:

Authors unsure about topical fit are welcome to contact the program committee co-chairs at

Review process and criteria

IMC 2021 invites two forms of submissions:

Any submission exceeding the short paper page-length limit will be evaluated as a full paper.

Authors should submit only original work that has not been published before and is not under submission to any other venue. We will consider full paper submissions that extend previously published short, preliminary papers (including IMC short papers), following the model of the ACM SIGCOMM policy.

IMC 2021 will bestow two awards on paper submissions, (1) a Best Paper award; and (2) a Community Contribution award. The best paper award will recognize the outstanding paper at the conference, and all accepted papers are eligible for it. The community contribution award will recognize a paper with an outstanding contribution to the community in the form of a new dataset, source code distribution, open platform, or other noteworthy service to the community. To be eligible for the community award, the authors must make data or source code publicly available or have a software artifact that is accessible and usable by the public at the time of the camera-ready deadline. The authors indicate their eligibility on the submission form and are also encouraged to include a link to the contribution in the submitted paper.

A few accepted papers may be forwarded for fast-track submission to IEEE/ACM Transactions on Networking.

Early Rejection

The review process will have several reviewing rounds. To allow authors time to improve their work and submit to other venues, authors of submissions for which there is a consensus on rejection will be notified early.

Anonymity Guidelines

Authors are expected to make a good-faith effort to anonymize papers. As an author, you should not identify yourself in the paper either explicitly or by implication (e.g., through the references).

Anonymization of important details are not required, if they are critical for the evaluation of the paper. For example, system names may be left de-anonymized, if the system name is important for a reviewer to be able to evaluate the work, and the paper may point to existing public datasets and artifacts that highlight or underscore the contributions outlined in the paper.

Please follow the following guidelines:

Additional details on paper anonymity are available here and in the statement released by the IMC Steering Committee here.


Research involving experiments with human subjects or user data (e.g., network traffic, passwords, social network information) should adhere to community norms. Any work that raises potential ethics considerations should indicate this on the submission form. The basic principles of ethical research are outlined in the Belmont Report: (1) respect for persons (which may involve obtaining consent); (2) beneficence (a careful consideration of risks and benefits); and (3) justice (ensuring that parts of the population that bear the risks of the research also are poised to obtain some benefit from it).

Research involving human subjects must be approved by the researchers’ respective Institutional Review Boards before the research takes place. Authors should indicate on the submission form whether the work involves human subjects, and, if so, if an IRB protocol has been approved for the research. We also expect that any research follows the practices and procedures of the institution(s) where the work is being carried out; for example, some universities require separate approval for the use of campus data. We expect researchers to abide by these protocols.

Some research does not involve human subjects yet nonetheless raises questions of ethics, which may be wide-ranging and not necessarily limited to direct effects. We encourage authors to be mindful of the ethics of the research that they undertake; these considerations are often not clear-cut, but often warrant thoughtful consideration. The program committee may raise concerns around the ethics of the work, and so we ask authors to outline these considerations explicitly in a separate appendix section (clearly marked with an appendix section heading “Ethics”), and when appropriate for context, in the body of the paper. The submission form will include a way to alert reviewers of this additional material.

Additionally, the program committee reserves the right to conduct additional evaluations and reviews of research ethics and reserves the right to independent judgment concerning the ethics of the conducted research.

Contact the program committee co-chairs at if you have any questions.

Submission guidelines

All submissions must satisfy the following requirements:

Formatting should be as follows:

Submissions that do not comply with these requirements will be rejected without review. The new ACM template style file satisfies the formatting requirements, provided you compile your source with options that produce letter page size and 10-point fonts. The following settings in your LaTeX source should achieve that (but please verify the output):


As an example, we also provide a sample template for ACM conference proceedings, which you can make use of.
