Linux Kernel Developers' Netconf 2015

(Kernel Summit Networking Workshop)


 

Netconf is a Linux community conference, by-invitation-only, running for the seventh year. The agenda has a clear focus on kernel level networking. Attendees are the main maintainers and developers of the Linux networking subsystem. Invitation is issued only 10-15 people who have provided significant contributions.

This winter, the Netconf joins the Netdev 0.1 held February 14-17, 2015 in Ottawa, Canada.

Due to the distributed nature of the Network subsystem development, contributors to the stack are located in different corners of the globe and coordinate security and bug fixes as well as maintenance and new features via email.

Netconf is intended to be a face to face working meetup to compliment those email exchanges. Problematic unresolved issues are hashed out and bold new ideas are discussed.
