The Workshop on ns-3 (WNS3) will be held as a fully virtual event, starting on June 23, 2021 and tentatively planned for two days. The objective of the workshop is to gather ns-3 users and developers, together with networking simulation practitioners and users, and developers of other network simulation tools, to discuss the ns-3 simulator and related activities.

As in past years, the conference organizers will apply to ACM to publish accepted papers in the ACM ICPS series.

The WNS3 is traditionally part of a week-long annual meeting for ns-3, including training and other activities related to ns-3 use and development, including the annual meeting of the ns-3 Consortium. The schedule for the full week is not yet prepared.
