To provide a stable service using resources such as computers and storages connected to a network, it is important to have a guaranteed bandwidth on the network. The G-lambda project, which AIST, KDDI R&D labs, NTT and NICT are promoting, in cooperation with the US Enlightened computing project, successfully conducted an experiment in which bandwidth between Japan and the US and computing resources in Japan and the US were simultaneously reserved and the applications were executed. This was the first experiment carried out at such scale in the world.
