What's New
- Papers can be submitted to a new Frontiers Track, intended for bold ideas without necessarily a complete evaluation.
- Prior to a full review, papers will be prescreened based on their Introduction to determine suitability for NSDI.
- An author can submit at most eight (8) papers to NSDI '27 across all submission deadlines.
Overview
NSDI focuses on the design principles, implementation, and practical evaluation of networked and distributed systems. We bring together researchers from the networking and systems community to foster a broad approach to addressing overlapping research challenges.
NSDI provides a high-quality forum for presenting results and discussing ideas that advance the knowledge and understanding of the networked systems community, continue a significant research dialog, or push the architectural boundaries of networked services.
Topics
NSDI invites innovative solutions for significant problems involving networked systems, including the following topics:
- Cloud and multi-tenant systems
- Distributed storage and caching
- Distributed query processing systems
- Experience with deployed networked systems
- Highly available and reliable networked systems
- Management, debugging, and diagnosis of problems in networked systems
- Mobile and embedded/sensor applications and systems
- Network and workload measurement systems
- Networked systems for big data
- Networked systems for machine learning (ML) and ML for networked systems
- Security and privacy of networked systems
- Self-organizing, autonomous, and federated networked systems
- Sustainable, low-energy, and low-carbon networked systems
- Systems aspects of networking hardware and physical layer communication
- Testing and verification of networked systems
- Virtualization and resource management for networked systems
Papers with no contributions to the design of networked systems or the networking stack are out of scope. Moreover, NSDI does not include work in the following topics:
- Hardware architecture: voltage scaling, GPU resource scheduling, hardware-level fault tolerance
- Physical layer: beamforming, modulation techniques, communication through unconventional mediums (capacitative, inductive, acoustic)
- Sensing and localization: gesture sensing, environment mapping, remote sensing
- User interfaces
Two Deadlines
NSDI '27 has two submission deadlines. Accepted papers will be presented at the conference and will appear as part of the proceedings. Prior to the conference, authors may advertise their papers as accepted by NSDI.
One-Shot Revision
Papers that are not accepted may be given the option of a one-shot revision. In such cases, reviewers will provide a list of issues to be addressed for the paper to be accepted. Authors may then resubmit a revision in the subsequent deadline, which may be for NSDI in the following year. One-shot revisions must include auxiliary material with (1) a version of the paper highlighting all changes made and (2) a high-level explanation of the major changes. The revision will be reviewed, to the extent possible, by the same reviewers. Revisions not addressing the required issues will be rejected without the option for subsequent one-shot revisions. To review one-shot revisions, PC members who give one-shot-revision decisions for the fall deadline are required to participate as external reviewers in the following year.
During the revision period, the paper is considered under review to NSDI. Per the USENIX Submission Policy, the paper cannot be submitted to other conferences unless the authors first withdraw it from consideration.
Submission Tracks
NSDI '27 has three tracks for which papers can be submitted: research, frontiers, and operational systems. Each paper needs to indicate to which track they are submitting. A paper may be submitted to at most one track, and the paper will be reviewed solely for that track. Once submitted to a track, a paper cannot change tracks, and the final program will indicate the tracks of accepted papers. The tracks are the following:
Traditional Research Track. This is the traditional track for NSDI, intended for research papers that present novel ideas with thorough evaluations. Strong research track submissions articulate a new or untested idea and provide compelling evidence in the form of experiments or models to test the success of the idea towards building networked systems.
Frontiers Track. This track is intended for papers that describe bold ideas with a high degree of novelty but may not have yet had a full evaluation. Papers should nonetheless present some evidence that the ideas are promising. This track is not intended for “early-stage” work that might later turn into a “full” paper, but instead for work that is simply challenging to evaluate in the traditional sense. Reasons that a novel idea may be challenging to evaluate traditionally include (but are not limited to): projects where a thorough evaluation would require resources beyond those of an academic institution (e.g., a proposal for a new LEO architecture), because the contributions are hard to evaluate numerically (e.g., a new perspective on the End to End argument), or because the proposal takes a significant first step on an agenda that will take many years to evaluate (e.g., a early synthesized results for a new hardware feature that will take years to test with a full “tape-out”). Frontiers track papers should articulate what aspects of their proposal are able to be evaluated, and what aspects are challenging to evaluate and why.
Operational Systems Track. This track is intended for papers that describe the design, implementation, analysis, and experience with large-scale operational systems and networks. We encourage the submission of papers that disprove or strengthen existing assumptions, deepen the understanding of existing problems, and validate known techniques at scale or in environments in which they were never used or tested before. Such operational papers need not present new ideas to be accepted, but instead focus on lessons learned from deployment that might deepen the research community’s understanding of both theory and practice of systems development. Papers that propose novel systems designs which are deployed, but that do not reflect deeply on lessons from deployment are a better fit for the traditional research track.
Assigning Papers to Tracks: Authors should indicate on the title page of the paper and in the submission form which track they are submitting to. Once submitted, papers cannot change tracks. Papers will be identified by track in the final program.
The rules regarding submission and anonymization are different for operational systems track papers, because the evaluation of such papers requires understanding the real-world use of the system. Authors' names should be withheld, as usual, but submissions may keep company names, links, real system names, etc.
Prescreening Phase
NSDI has made some modifications to the review process to address the increase in the number of submissions and load on reviewers. Submissions will undergo a prescreening phase, where reviewers will read the first section of the paper after the abstract (“Introduction”), which should have no more than 3 pages, and they will check if the submission meets some minimum criteria: (a) the subject of the paper falls within the scope of the conference based on the topics listed above; (b) the exposition is understandable by a PC member who has published in the NSDI community, but may not have expertise in the subfield; and (c) the introduction articulates its intellectual contributions and evaluative claims in a way that conforms to the submitted track:
- For the Traditional Research Track, it articulates a novel idea and presents some evidence from an evaluation as to the promise of the idea.
- For the Frontiers Track, it articulates a novel idea that is not merely an incremental spin on related work, and one would not expect a graduate student to be able to completely implement and evaluate the idea during the course of a PhD.
- For the Operational Systems Track, it describes an operational system articulating the deployment setting and scale, and presents lessons learned from the operational setting that are relevant to the NSDI community.
Policy on NSDI Resubmissions
Papers rejected from NSDI and not given a one-shot revision option cannot be submitted to the next deadline, which may be for the same NSDI or the following NSDI. For example, a paper rejected from the spring deadline cannot be submitted to the fall deadline of the same NSDI, while a paper rejected from the fall deadline cannot be submitted to the spring deadline of the following NSDI. Papers given a one-shot revision option that are submitted to the immediate next deadline, can only be submitted as a one-shot revision with the required auxiliary material.
Extensions of Workshop Papers
Work that extends an author's previous workshop paper is welcome, as long as the NSDI submission includes substantial new material that has been developed since the publication of any earlier version. Authors must (a) acknowledge its previous workshop publications with an anonymous citation in the paper, (b) indicate the deanonymized citation in the submission form, and (c) provide a short explanation of the differences between the NSDI submission and the prior workshop paper in the submission form. However, NSDI submissions cannot be concurrent with submission to a workshop venue. If the notification date for the workshop submission is after the submission date for NSDI, this is a concurrent submission.
Resubmission of prior SIGCOMM and HotNets Papers
Authors are free to submit SIGCOMM rejected papers to NSDI and significant extensions of HotNets accepted papers, provided that the notifications from these conferences occur before the NSDI submission deadline.
Author Limit
An author can be listed on at most eight submissions or accepted papers to NSDI '27 across all submission deadlines. If this policy is violated, papers will be desk rejected until the limit is respected.
What to Submit
NSDI is double-blind: authors should make a good faith effort to anonymize papers, with some exceptions for the operational track papers as noted above. As an author, you should not identify yourself in the paper either explicitly or by implication (e.g., through the references or acknowledgments). Take the following steps when preparing your submission:
- Remove authors' names and affiliations.
- Remove acknowledgment of people and funding sources.
- Omit links to your own online content. If this online content is critical to the content of your paper, you can include it in the submission form as auxiliary material, or contact the program co-chairs.
- Use care in naming your files. Source file names, e.g., Joe.Smith.dvi, are often embedded in the final output.
- Use care in referring to related work, particularly your own. Do not omit references to provide anonymity. Instead, cite your past work in the third person. If you cite anonymous work, you must enter the de-anonymized citation on the online submission form.
- If you must cite another concurrent submission to NSDI on a related topic, include the following text in the citation list: "Under submission. Details omitted for double-blind reviewing."
Submissions and final papers must be no longer than 12 pages, including footnotes, figures, and tables. Submissions may include additional pages for references and for supplementary material in appendices. The paper should stand alone without the supplementary material, but authors may use this space for content that may be of interest to some readers but is peripheral to the main technical contributions of the paper. Reviewers are not required to read this material when reviewing the paper.
Submissions must be in two-column format, using 10-point Times-Roman or similar font, on 12-point leading, in a text block 7" wide x 9" deep, with .33" inter-column space, formatted for 8.5" x 11" paper.
Papers not meeting these criteria will be rejected without review, and no deadline extensions will be granted for reformatting. Pages should be numbered, and figures and tables should be legible when printed without requiring magnification. Authors may use color in their figures, but the figures should be readable when printed in black and white. If you wish, you may use the template for LaTeX available on the conference paper templates page. All papers must be submitted via the submission form. Please do not email submissions.
On the Use of Generative AI
Authors must not submit papers produced entirely or substantively by generative AI. Using AI to write an entire section, including the related work section or conclusion, constitutes a violation of this policy. Authors must provide a statement attesting that all text was primarily human written as part of the submission process in HotCRP. At the same time, we encourage the use of AI tools for improving the grammar and clarity of human-written text. For any questions about the appropriate use of generative AI, contact the program co-chairs.
Other Policies
Simultaneous submissions: Simultaneous submission of the same work to multiple venues, submission of previously published work, or plagiarism constitutes dishonesty or fraud. USENIX, like other scientific and technical conferences and journals, prohibits these practices and may take action against authors who have committed them. See the USENIX Conference Submissions Policy for details.
Technical reports: NSDI allows submissions to be concurrently available as technical reports (e.g., at arXiv), provided that the authors use a different title and system name in their submission for anonymization.
Nondisclosure agreement: Papers accompanied by nondisclosure agreement forms will not be considered. All submissions will be treated as confidential prior to publication on the NSDI website; rejected submissions will be permanently treated as confidential.
Authors uncertain whether their submission meets USENIX's policies should contact the program co-chairs.
Conflicts
At submission time, you must provide information about conflicts with PC members. A PC member is a conflict if any of the following three circumstances applies:
Institution: You are currently employed at the same institution, have been previously employed at the same institution within the past two years (not counting concluded internships), or are going to begin employment at the same institution during the review period.
Advisor: You have a past or present association as thesis advisor or advisee.
Collaboration: You have a collaboration on a project, publication, grant proposal, program co-chairship, or editorship within the past two years.
Personal: The authors judge that the reviewer may be biased in reviewing the work for other reasons. These conflicts are expected to be rare; authors should contact the program co-chairs with an explanation whenever a personal conflict is declared.
You may not identify a PC member as a conflict if none of these circumstances applies, even if you want to avoid them as reviewers. The chairs will review paper conflicts to ensure the integrity of the reviewing process, adding or removing conflicts if necessary. The chairs may reject submissions on the basis of egregious missing or extraneous conflicts. If you have any questions about conflicts, contact the program co-chairs.
Ethical Considerations
Papers describing experiments with users or user data (e.g., network traffic, passwords, social network information) should follow the basic principles of ethical research, e.g., beneficence (maximizing the benefits to an individual or to society while minimizing harm to the individual), minimal risk (appropriateness of the risk versus benefit ratio), voluntary consent, respect for privacy, and limited deception. When appropriate, authors are encouraged to include a subsection describing these issues. Authors may want to consult the Menlo Report for further information on ethical principles, or the Allman/Paxson IMC '07 paper for guidance on ethical data sharing.
Authors must, as part of the submission process, attest that their work complies with all applicable ethical standards of their home institution(s), including, but not limited to, privacy policies and policies on experiments involving humans. Submitting research for approval by one's institution's ethics review body is necessary, but not sufficient—in cases where the PC has concerns about the ethics of the work in a submission, the PC will have its own discussion of the ethics of that work. The PC's review process may examine the ethical soundness of the paper just as it examines the technical soundness.
Processes for Accepted Papers
If your paper is accepted and you need an invitation letter to apply for a visa to attend the conference, please contact [email protected] as soon as possible. Visa applications are reportedly taking more than three months to process. Please identify yourself as a presenter or an author, and include your mailing address in your email request.
Accepted papers will be shepherded through an editorial review process by a member of the Program Committee. Based on initial feedback from the Program Committee, authors of shepherded papers will submit an editorial revision of their paper to their Program Committee shepherd. The shepherd will review the paper and give the author additional comments. Authors will upload their final file to the submission system by the final paper deadline for the conference proceedings.
By submitting a paper, you agree that if the paper is accepted, at least one of the authors will register to attend the conference at full price (i.e., not the student rate) and to present the paper; USENIX members at the Sustainer level and higher may apply their membership discounts to their registrations. If an author plans to present more than one paper, one full-price registration will still be required for each paper.
All papers will be available online to registered attendees before the conference. If your accepted paper should not be published prior to the event, notify [email protected]. The papers will be available online to everyone beginning on the first day of the conference.
Best Paper Awards
Awards will be given for the best paper(s) at the conference.
Community Award
To encourage broader code and data sharing within the NSDI community, the conference will also present a "Community Award" for the best paper whose code and/or data set is made publicly available by the final paper deadline. Authors who would like their paper to be considered for this award will have the opportunity to tag their paper during the submission process.
