====== 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**.
