Dear P4 community: We are writing to inform you we have *extended the deadline *for submitting proposals for talks, demos, and posters for the P4 Workshop 2019 at Stanford University.The extension will be granted through *March 15, 2019 11:59pmPDT*. Thanks to all who have submitted proposals already! We are particularly interested in hearing from groups developing P4 code for real systems and deployments, as well as new use cases that take the P4 language in interesting, new directions. We would like to keep the workshop focused on technical content -- i.e., talks and demos should be used to showcase P4 in action and not for product marketing. To submit a proposal, please upload a one-page PDF to the submission site below: Submission site: https://p4workshop.cs.cornell.edu <https://p4workshop.cs.cornell.edu/> Notification: March 25, 2019 To stay updated on all details of the workshop, please refer to the event webpage on P4.org <https://p4.org/events/2019-05-01-p4-workshop/>.
