====== FDT Results ====== Below we list a simple experiment that transfers a 478M file from a server with hostname "net-server-2" to a client with hostname "net-server-1" over a 1Gbps link. We assume FDT is installed on both machines in directory "~/fdt". Create the file and host the FDT server: <code> [net-test-2]# cd ~/fdt [net-test-2]# dd if=/dev/zero of=500-file.data bs=1MB count=500 [net-test-2]# md5sum 500-file.data [net-test-2]# ./fdtServer.sh </code> Use the client to copy the file from the server: <code> [net-test-1]# cd ~/fdt [net-test-1]# ./fdtClient.sh -pull -c net-test-2 500-file.data -d . [net-test-1]# md5sum 500-file.data </code> For this test with RTT of **0.010ms**, we have a transfer period of **16s**, or a throughput of **239Mbps**. Note that there is a BDP of 0.010ms * 1Gbps = **1.31072KB**. We had a Net In average of **450.251Mbps** and Avg: **450.251Mbps**, with Avg disk write of: **225.103Mbps**. Using the dummynet with a RTT set to **100ms**, we have a transfer period of **20s**, or a throughput of **191.2Mbps**. Note that there is a BDP of 100ms * 1Gbps = **12.8MB**. We had a Net In average of **309.842Mbps** and Avg: **398.217Mbps**, with Avg disk write of: **265.46Mbps**. By default FDT uses 4 parallel streams, now we will test the transfer with 8 parallel streams: <code> [net-test-1]# cd ~/fdt [net-test-1]# ./fdtClient.sh -pull -c net-test-2 500-file.data -d . -P 8 [net-test-1]# md5sum 500-file.data </code> Using the dummynet with a RTT set to **100ms**, we have a transfer period of **19s**, or a throughput of **201.3Mbps**. Note that there is a BDP of 100ms * 1Gbps = **12.8MB**. We had a Net In average of **796.343Mbps** and Avg: **796.343Mbps**, with Avg disk write of: **398.052Mbps**. ====== felCat4.2bit 806192 bytes, Mem-mem, 100ms RTT, 0 pkt loss ====== <code> through dummynet wan2 788mb cat (4 streams) 1. 22/04 21:28:58 Net In: 501.667 Mb/s Avg: 501.667 Mb/s 22/04 21:29:03 Net In: 575.637 Mb/s Avg: 538.659 Mb/s Transfer period: 22s 2. 22/04 21:29:51 Net In: 558.462 Mb/s Avg: 558.462 Mb/s 22/04 21:29:56 Net In: 605.479 Mb/s Avg: 581.919 Mb/s 22/04 21:30:01 Net In: 150.615 Mb/s Avg: 438.170 Mb/s 100.00% ( 00s ) Transfer period: 21s 3. 22/04 21:30:59 Net In: 437.020 Mb/s Avg: 437.020 Mb/s 22/04 21:31:04 Net In: 567.302 Mb/s Avg: 502.161 Mb/s 22/04 21:31:09 Net In: 310.019 Mb/s Avg: 438.113 Mb/s1 Transfer period: 22s through dummynet wan2 788mb cat (6 streams) 1. 22/04 21:42:21 Net In: 784.635 Mb/s Avg: 784.635 Mb/s 22/04 21:42:26 Net In: 529.316 Mb/s Avg: 656.897 Mb/s Transfer period: 17s 2. 22/04 21:43:24 Net In: 723.623 Mb/s Avg: 723.623 Mb/s 22/04 21:43:29 Net In: 589.816 Mb/s Avg: 656.640 Mb/s Transfer period: 19s 3. 22/04 21:44:10 Net In: 814.112 Mb/s Avg: 814.112 Mb/s 22/04 21:44:15 Net In: 500.012 Mb/s Avg: 656.949 Mb/s Transfer period: 17s through dummynet wan2 788mb cat (8 streams) 1. 22/04 18:41:07 Net In: 805.100 Mb/s Avg: 805.100 Mb/s 22/04 18:41:12 Net In: 510.615 Mb/s Avg: 657.828 Mb/s Transfer period: 17s 2. 22/04 21:26:38 Net In: 818.788 Mb/s Avg: 818.788 Mb/s 22/04 21:26:43 Net In: 496.035 Mb/s Avg: 657.298 Mb/s Transfer period: 17s 3. 22/04 21:28:04 Net In: 843.213 Mb/s Avg: 843.213 Mb/s 22/04 21:28:09 Net In: 471.038 Mb/s Avg: 657.004 Mb/s Transfer period: 17s through dummynet wan2 788mb cat (10 streams) 1. 22/04 21:46:16 Net In: 794.490 Mb/s Avg: 794.490 Mb/s 22/04 21:46:21 Net In: 521.501 Mb/s Avg: 657.982 Mb/s Transfer period: 18s 2. 22/04 21:47:18 Net In: 799.751 Mb/s Avg: 799.751 Mb/s 22/04 21:47:23 Net In: 515.986 Mb/s Avg: 657.826 Mb/s Transfer period: 17s 3. 22/04 21:49:16 Net In: 815.398 Mb/s Avg: 815.398 Mb/s 22/04 21:49:21 Net In: 500.277 Mb/s Avg: 657.790 Mb/s Transfer period: 17s through dummynet wan2 788mb cat (12 streams) 1. 22/04 21:39:35 Net In: 759.637 Mb/s Avg: 759.637 Mb/s 22/04 21:39:40 Net In: 557.083 Mb/s Avg: 658.340 Mb/s Transfer period: 18s 2. 22/04 21:40:31 Net In: 778.779 Mb/s Avg: 778.779 Mb/s 22/04 21:40:36 Net In: 537.939 Mb/s Avg: 658.335 Mb/s Transfer period: 18s 3. 22/04 21:41:19 Net In: 775.203 Mb/s Avg: 775.203 Mb/s 22/04 21:41:24 Net In: 541.706 Mb/s Avg: 658.354 Mb/s Transfer period: 18s </code> <code> ./fdtClient.sh -pull -c net-test-2 felCat4.2bit -d . -P 8 </code> {{http://chart.googleapis.com/chart?chs=250x100&chd=t:60,40&cht=p3&chl=Hello&.png?}}
