Dear Colleagues, PLNOG <http://plnog.pl/en> is an event where Polish Internet Service Providers, network operators and other interested parties get together. Although the meeting is mostly technical, it is also a chance for people to meet and network with others in their field. PLNOG18 will take place on March 6-7th, 2017 in Warsaw, Poland. The PLNOG Programme Committee is now seeking content proposals from the RIPE community for the plenary sessions, panels, workshops and tutorials at PLNOG18. See the full descriptions of the different presentation formats: http://2017.warszawa.plnog.pl/call-for-papers/. Proposals for plenary sessions, panels, workshops and tutorials must be submitted for full consideration no later than 8 January 2017. Proposals submitted after this date will be considered depending on the remaining available space in the programme. We are looking for presentations covering topics of network engineering and operations, including but not limited to: - IPv6 deployment - Network Security - Managing IPv4 scarcity in operations - Commercial transactions of IPv4 addresses - Data centre technologies - Network and DNS operations - Internet governance and regulatory practices - Network and routing security - Content delivery - Internet peering and mobile data exchange - Internet of Things (IoT) - Cloud PLNOG attendees are quite sensitive to keeping presentations non-commercial, and product marketing talks are strongly discouraged. Repeated audience feedback shows that the most successful talks focus on operational experience, research results, or case studies. For example, presenters wishing to describe a commercial solution should focus on the underlying technology and not attempt a product demonstration. If you have any questions or requests concerning content submissions, please email paulina[dot]tomaszewska[at]proidea[dot]org[dot]pl Kind regards, *Sylwia Wojtas* Head of Communication *tel:* 605 177 881 *e-mail: *sylwia.wojtas@proidea.org.pl *skype:* sylviawojtas
