At Interop Tokyo 2010, NTT Communications presented a 100 Gbps Ethernet network. 100 Gbps is fast enough to send the data volume of a Blu-ray disk in just two seconds.
"Now that the Internet is shifting to video, carriers and ISPs are using much more bandwidth, so traffic management is very difficult. Currently, the top speed is 10 Gbps, and 2 or 3 networks are bundled for large data volumes. So if a 100 Gbps interface appears, all this traffic can be managed using a single interface, making things easier for operators. So we've provided this 100 Gbps Ethernet to support, for example, even a tenfold increase in traffic."
Every year, Interop Tokyo features ShowNet, a huge network demo on site. This year's ShowNet used 100GBASE-LR4, one type of 100 Gbps Ethernet about to be standardized by the IEEE as a next-generation, ultra-fast network. It was operated as a carrier backbone network connecting the Interop site with the Internet.
This was the first time worldwide that 100 Gbps Ethernet access was provided for an actually operational network.
"First of all, Internet access is from our NTT Otemachi Building. There's an Internet network here at the Makuhari complex, called ShowNet, and that's connected to Otemachi in a form resembling a simulated ISP. The idea is that the traffic between the two is connected using new technology in the form of the 100 Gbps Ethernet."
"This is a transmission device called a DTN, from Infinera. The transmission distance from the fiber side here to NTT Otemachi is over 50 km. This interface is the user interface, and 100 Gbps traffic flows from here to a CRS-3 router from Cisco Systems. With this interface, there are separate cores for sending and receiving, and each carries 100 Gbps traffic."
"This 100GBASE-LR4 technology is likely to become the standard for carrying 100 Gbps traffic. It enables current physical fibers or cables to be used as-is, so to achieve 100 Gbps, all you need to do is change the interface. This year, we've exhibited the technology under more realistic conditions, so we hope people get a feeling for what the near future will bring."
