Martin (4),Next years transatlantic link,A call for tender is starting with the following objectives: increase the transatlantic bandwidth to OC-12c (612Mbps) move the Chicago PoP to the STAR
4、LIGHT keep T3 commercial Internet access, but have an additional (backup?) access in Europe keep (ATM) connectivity to the STARTAP aim at direct peerings with North American R&D networks at the STARLIGHT over Gigabit Ethernet All this is a natural extension of the existing setup,10/10/2018,CERN Upda
5、te & DataTAG Project,Olivier H. Martin (5),Dedicated lambda for research,What is new is that the call for tender also includes an option for a 2.5 Gbps transatlantic lambda, which will be dedicated to Grid applied network research The aim is to have a dedicated testbed where new things can be tried
6、out without affecting production traffic One of our major concerns is tcp/ip performance over large bandwidth*delay networks Single vs multi stream performance Auto-tuning,10/10/2018,CERN Update & DataTAG Project,Olivier H.
