University of Tokyo Establishes 7.2 Gbps Transcontinental Download Rate

The University of Tokyo, Chelsio Communications, a supplier of 10-Gigabit Ethernet server adapters and protocol acceleration technology, and an international team of engineers established the world's longest 10 Gigabit per second link ever recorded for the transmission of Internet data by connecting two AMD Opteron processor-based servers over three continents, spanning 17 time zones and reaching more than half way around the world. Each server was equipped with a Chelsio 10 Gigabit Ethernet Protocol Engine with TCP/IP offload technology. A transfer rate of 7.21 Gbps was sustained using a single TCP stream and standard 1500-byte Ethernet frames over trans-continental link, breaking the world record. At this transfer rate and distance, a full-length DVD can theoretically be transferred anywhere on the earth in under 5 seconds.


At 10 Gbps rates, it's widely accepted that CPU throughput limits performance. Chelsio said its TCP/IP offload engine (TOE) technology enables higher CPU throughput. The company also described AMD's Direct Connect Architecture as the best approach of directly connecting CPU, memory, and I/O resources.
