The Taj network, funded by the U.S. National Science Foundation (NSF), has expanded to the Global Ring Network for Advanced Application Development (GLORIAD), and now connects India, Singapore, Vietnam, and Egypt to the GLODRIAD global infrastructure. The Taj network will support every knowledge discipline, including high-energy physics, atmospheric and climate change science, renewable energy, nuclear nonproliferation, genomics, medicine, economics, and history. The population of countries with access to the NSF-sponsored GLORIAD program now exceeds half the world.
"Science is increasingly data driven and collaborative, and does not respect national borders," says NSF's Ed Seidel. "High speed optical networks are critical to both national and international scientific efforts."
NSF's Bill Change says the Taj network provides a new model of international cooperation, will make sharing global network management tasks easy, and focuses on user-leave performance.
The Taj expansion significantly extends GLORIAD's existing research and education network and upgrades existing U.S.-China network service from 2.5 Gbps to 10 Gbps, allowing for the placement of high capacity network applications on dedicated lightpaths. Taj principal investigator Greg Cole says the network dramatically expands the world's science infrastructure by connecting scientists, educators, and students with the most advanced services available.
