TOPIC    A One Year Measurement Study of IPv6 Inter-Domain Traffic
             in the Internet

DESCRIPTION 

             Recent concern over the impending exhaustion of IPv4
             allocations has re-energized interest in the status of IPv6
             deployment in the Internet. While previous studies have
             explored rates of IPv6 registry allocations or BGP statistics,
             little data exists on the overall level of IPv6 traffic.

             In this talk, Arbor Networks researchers will present the
             results of a one year study on IPv6 traffic in the Internet
             from July 2007 to July 2008. In cooperation with the
             University of Michigan and over 90 Internet providers, Arbor
             leveraged commercial traffic probes to measure inter-domain
             IPv6 traffic (both native and tunneled) in the Internet.

             Their dataset covered 91 ISPs including one quarter of the
             tier 1 ISPs and a sizable percentage of the regional / PTT
             providers in North America and EMA. In all, Arbor monitored
             2,389 peering and backbone routers, 278,268 customer and
             peering interfaces and some 5 terabits per second of average
             daily Internet inter-domain traffic. As a result, Arbor
             researchers will report on both the overall level of IPv6
             traffic as well as regional differences and annual trends in
             IPv6 traffic growth.

ABOUT NANOG44

North American Network Operators' Group (NANOG) is an educational and operational forum for the coordination and dissemination of technical information related to backbone/enterprise networking technologies and operational practices.

NANOG meetings are held three times each year, and include presentations, tutorials, and BOFs. The meetings are informal, and membership is open. Conference participants typically include senior engineering staff from tier 1 and tier 2 ISPs. Participating researchers present short summaries of their work for operator feedback.

NANOG meetings are organized by Merit Network, Inc., a non-profit Michigan organization, and are hosted by Merit and other organizations around the U.S. and Canada. Overall leadership is provided by the NANOG Steering Committee, established in 2005, and the Program Committee.
