Dear Colleagues,

RIPE 64 takes place on 16-20 April 2012 in Ljubljana, Slovenia.

The RIPE Programme Committee (PC) is now seeking content proposals from the RIPE community for the Plenary, BoF and tutorial sessions at RIPE 64. The PC seeks presentations covering topics of network engineering and operations, including but not limited to:

• IPv6 deployment • 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

Submissions ------------ Attendees of the RIPE meetings 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. Presenters who are proposing a panel or BOF are encouraged to include speakers from several (perhaps even competing) companies and/or a neutral facilitator. Presenters should indicate how much time they will require (30 minutes is a common maximum duration, although some talks can be longer).

Proposals for presentations must be submitted for full consideration no later than *3 February* using the online topic submission system at: http://meetings.ripe.net/pc/

Presentations submitted after this date will be considered on a space-available basis.

In addition to presentations selected in advance for the plenary, the RIPE PC also offers several timeslots for “lightning talks” which are selected immediately before or during the conference. Lightning talks are short (10 mins maximum) and often involve more timely topics. Lightning talks will be announced shortly before the conference.

If you are aware of a talk that might be interesting to the community, please provide us with the details and we will approach the potential speaker.

If you have any questions or requests concerning content submissions, please email pc@ripe.net.

Andrei Robachevsky On behalf of the RIPE Programme Committee
