Researchers from Caltech and CERN set a new Internet2 Land Speed Record by transmitting a single IPv6 stream at 983 Mbps for more than an hour from Geneva, Switzerland to Chicago, Illinois, a distance of 7,067 km (more than 4,000 miles). The new record was set through the efforts of the DataTAG project and CERN using a standard Linux TCP implementation. The researchers said 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. 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 online.http://lsr.internet2.edu
- Caltech and CERN also hold the current Internet2 Land Speed Record in the IPv4 class. The team transferred one terabyte of data across 10,037 km (Sunnyvale, California to Geneva, Switzerland) in less than one hour at a sustained TCP rate of 2.38 Gbps.

The DataTAG project, which is co-funded by the European Community and the US, is testing a large-scale intercontinental grid computing testbed. The project addresses a number of high-performance networking issues, including sustained and reliable high performance data replication, end-to-end advanced network services, and novel monitoring techniques. http://datatag.web.cern.ch/datatag/
