Annual Retreat
Fall 2019

Overview

The Network Programming Initiative (NPI) conducts annual Retreats to bring together faculty, students, postdocs, and industry partners for a one-day workshop with presentations, panels, and informal discussions related to network programming. Topics include practical use cases and solutions encompassing languages, algorithms and tools.

The Fall 2019 Retreat was held on Friday, October 11, 2019 in the Tata Innovation Center at the Cornell Tech campus on Roosevelt Island.
