And while I do love the idea of having 100gbit national infrastructure, I do hope that they are using newer versions of linux than 2.6.33 to develop it with. See pages 24 and experimental network setup is shown in Figure 4.1. It was called the Long Island MAN (LIMAN) testbed, and was supported by ESnet as a DOE-funded testbed for networking research. The high-performance hosts, W1 (West 1), E1 (East 1), and E2 (East 2), were Intel Xeon Nehalem E5530 models (2.4GHz CPU, 24GB memory) and ran Linux version 2.6.33. The application hosts, WA (West App-host) and EA (East App-host), were Intel Dual 2.5GHz Xeon model and ran Linux 2.6.18. The routers, WR (West Router) and ER (East Router), were Juniper MX80's running Junos version 10.2. The link rates were 10 Gbps from the high-performance hosts to the routers, 1 Gbps from the application hosts to the routers, and 10 Gbps between the routers --=20 Dave T=E4ht Fixing bufferbloat with cerowrt: http://www.teklibre.com/cerowrt/subscribe.= html
