ESLEA-FABRIC: 4 Gbit flows over GÉANT u Set up 4 Gigabit Lightpath Between GÉANT Po. Ps n Collaboration with Dante n GÉANT Development Network London – Amsterdam and GÉANT Lightpath service CERN – Poznan n PCs in their Po. Ps with 10 Gigabit NICs u VLBI Tests: n UDP Performance l Throughput, jitter, packet loss, 1 -way delay, stability n Continuous (days) Data Flows – VLBI_UDP and n multi-Gigabit TCP performance with current kernels n Experience for FPGA Ethernet packet systems u Dante Interests: n multi-Gigabit TCP performance n The effect of (Alcatel) buffer size on bursty TCP using BW limited Lightpaths ESLEA Bits&Bytes, Manchester, 7 -8 Dec 2006, R.
