Overview TCP and UDP Test Results

In this page and overview has been given of the Netherlight Lambda network measurements which are classified according to the skeleton presented in the "TCP and UDP Configurations" document. The result views are presented in the form of hyperlinks. When clicked, these results will all appear in the same new browser window.

In this section all TCP bulk transfer tests, executed with Iperf or Netperf, has been presented.
