New High Performance Transport Protocol for High Performance Data Intensive Science Applications Demonstrated at SC09 Conference in Portland, Oregon

November 17, 2009

Portland, Oregon

Today, at the International Conference for High Performance Computing, Networking, Storage, and Analysis (SC09) conference, a research consortium demonstrated a new high performance transport protocol, UDX, for data intensive science applications. The UDX demonstration transported 9.3-9.6 Gbps streams using US national 7,000 mile testbed, C-Wave, based on lightpath channels within optical fiber.

Traditional Internet transport protocols were designed many years ago, at a time when networks had extremely limited bandwidth capacity. These earlier technologies provide only limited support for extremely large capacity, high volume streams required by large scale 21 st century science. The new UDX protocol was specifically designed to eliminate those limitations and to optimize today's high capacity networking capabilities, especially lightptah channels implemented in high performance optical fiber channels. The UDX protocol can support sustained high performance, capacity streams across continents and the world for many hours, days or weeks.

The UDX protocol was designed by the Laboratory for Advanced Computing at the University of Illinois at Chicago. This technology is being developed and evaluated on the national TeraFlow network testbed and an extension on the national C-Wave, which was used for the SC09 demonstration. The testbed facilities, networking experiments, and demonstrations are being undertaken in partnership with the International Center for Advanced Internet Research (iCAIR) at Northwestern University. To address the challenges of 21 st century large scale data transport requirements, this research consortium is designing, developing, and implementing an advanced communication services that can support data intensive traffic streams not only for individual large scale science projects, but also for more general applications such as next generation cloud computing.

These experiments and the Teraflow tesbed are funded by the national Science Foundation (NSF). Additional support has been provide by the StarLight international communications exchange facility, the National Lambda Rail, and Cisco Systems.
