NEXT GENERATION INTERNET PROTOCOL
MARKS SHATTERED
An international team set new Internet2 Land Speed Records using next
generation Internet Protocols (IPv6) by achieving 983 megabits-per-second with
a single IPv6 stream for more than an hour across a distance of 7,067
kilometers (more than 4,000 miles) from Geneva, Switzerland to Chicago, Ill.
The record is comparative to transferring the equivalent of approximately one
feature-length DVD-quality movie every 36 seconds, or more than 3,500 times
faster than the typical home broadband connection.
The record setting team consisted of members from the California Institute
of
Technology (Caltech) and CERN. The new records were set through the efforts of
the DataTAG project and CERN using a standard Linux TCP implementation,
demonstrating the broad possibilities of today's high-performance networks.
Major sponsorships came through the support of the European Union, the U.S.
National Science Foundation, the Electronic Visualization Lab at the
University of Illinois in Chicago and the U.S. Department of Energy through
Caltech.
"This record demonstrates the ability of IPv6 to support gigabit per second
class speeds over intercontinental network links," said Olivier Herve Martin,
Head of External Networking at CERN and Manager of the European Union DataTAG
project. "The record further proves that real science data can be transported
around the globe in a timely manner and underscores that we are reaching
network performance enabled international scientific collaboration."
Harvey Newman, Professor of Physics at Caltech and U.S. Compact Muon
Solenoid
Collaboration Board Chair added, "The efficient use of long distance networks
at gigabit per second speeds is critical to the future of the high energy and
nuclear physics community. This demonstration of gigabit per second transfers
over intercontinental distances using IPv6 marks an important milestone in the
development of our facilities and protocols needed to support the data
analysis needs and the mission of emerging experimental programs in high
energy physics."
"Matching efforts in the global academic community, the Internet2 community
in
the United States is actively deploying IPv6 on campus, regional and national
backbone networks," said Guy Almes, Chief Engineer for Internet2. "This new
record shows that IPv6, crucial to the Internet's continued scalable growth
and innovation, also supports the stringent high-performance networking
requirements of research and education."
The Internet2 Land Speed Record is an open and ongoing competition. Details
of
the winning entries, complete rules, submission guidelines and additional
details are available at: lsr.internet2.edu/.
Caltech and CERN also hold the current Internet2 Land Speed Record in the
IPv4
class, in collaboration with the Stanford Linear Accelerator Center (SLAC) and
the Los Alamos National Laboratory. The team transferred one terabyte of data
across 10,037 kilometers (more than 6,000 miles) in less than one hour, from
Sunnyvale, Calif., to Geneva, Switzerland. This corresponds to a sustained TCP
rate of 2.38 gigabits per second for more than one hour.
