Setup

It is the intension to control plasma physics experiments, situated at the IPP institute in Jülich, near Achen, Germany, by the FOM institute in Nieuwegein, near Utrecht, the Netherlands (see below for a short description of the sites). Therefore, it has to be investigated if their is sufficient network performance available between these two sites. The route between the sites is provided by the SURFnet, TEN-155 and DFN networks.

To be able to differentiate between the congestion sources in the involved networks, the following test setup with the sites, specified in table 5, has been configured.

 

Table: Sites participating in the network performance tests for network route IPP - FOM. The Title columns are again referring to the titles used in the Web pages.

The host at the FOM site (table 5) is used as control host. However, this host does not possess a HTTPD server. Therefore, the results are copied to the IPP host for the Web⁶ presentation. The possibility to copy the results to another host is a feature of the package. In contradiction to the DAS monitor (subsection 3.2) here are no extra Quality-of-Service test connections used, but on the other hand the measurements are performed in two directions. This leads to a somewhat different presentation of the data in the tables.
