Demonstration of Layer-1 Bandwidth-on-Demand (L1 BoD) Service (2008.12.2)
We successfully demonstrated layer-1 BoD between Kyushu University and Hokkaido University (about 1800 km).
Two layer-1 paths (totaling 2 Gbps) were established with no negative effect for other services between Hokkaido University and Kyushu University. After hitlessly reducing bandwidths of L2/L3 paths by 2Gbps by LCAS, two L1 paths were established on demand via client PC at Hokkaido Univ. Non-compressed HDTV was transmitted between the sites very stably.
