SUMMARY:Observed Relationships between Size Measures of the Internet or Is
  the Internet really just a star network after all? - Brian Carpenter (Uni
 versity of Auckland)

DESCRIPTION:This talk covers some observations on the relationships betwee
 n three measures of the size of the Internet over more than ten years. The
  size of the BGP4 routing table\, the number of active Autonomous Systems\
 , and the total size of the Internet\, have fairly simple relationships de
 spite the Internets growth by two orders of magnitude. In particular\, the
  size of the BGP4 system appears to have grown approximately in proportion
  to the square root of the size of the globally addressable Internet. A si
 mple model that partially explains this square law is described. This offe
 rs a way to understand and monitor the scaling of the BGP4 system.\n\nBIO:
  Brian E. Carpenter joined the University of Auckland in September 2007. H
 e was appointed Professor in January 2009. Before that\, he spent ten year
 s with IBM at various locations\, working on Internet standards and techno
 logy. From 1997 he was at IBM's Hursley Laboratory in England. From 1999 t
 o 2001 he was at iCAIR\, the international Center for Advanced Internet Re
 search\, sponsored by IBM at Northwestern University in Evanston\, Illinoi
 s. He was most recently based in Switzerland as a Distinguished Engineer a
 nd a member of the IBM Academy of Technology.\n\nBefore joining IBM\, he l
 ed the networking group at CERN\, the European Laboratory for Particle Phy
 sics\, in Geneva\, Switzerland\, from 1985 to 1996. This followed ten year
 s' experience in software for process control systems at CERN\, which was 
 interrupted by three years teaching undergraduate computer science at Mass
 ey University in New Zealand.\n\nHe holds a first degree in physics (Downi
 ng College\, Cambridge) and a Ph.D. in computer science (University of Man
 chester)\, and is a Chartered Engineer (UK). He has been an active partici
 pant in the Global Grid Forum\, and in the Internet Engineering Task Force
  (IETF)\, where he has worked on IPv6 and on Differentiated Services. He s
 erved from March 1994 to March 2002 on the Internet Architecture Board\, w
 hich he chaired for five years. He also served as a Trustee of the Interne
 t Society\, and was Chairman of its Board of Trustees for two years until 
 June 2002. He was Chair of the IETF from March 2005 to March 2007.\n
