Overview Net Tests between @[HOSTS_TITLE] Hosts

Introduction

This page gives an overview of the net test results at a particular date and time. This page contains the following two main segments:

  1. A control frame which can be used to present the net test data in various ways.
  2. A table frame where the data are actually presented.
Both frames are described in the following sections.

This page requires minimal Netscape 4, Internet Explorer 4 or HotJava 3.

Control frame

The top control frame can be used to select the desired net test data. It is placed above all tables. The functionality of the control frame is for all tables more or less comparable. See also the help page for more information. In this page the procedure is also discussed for loading the net test data from the Web server.

Table frame

In the bottom table frame a total overview is given from the net test results of the @[HOSTS_TITLE] hosts. Going from above to below the following items can be found in this frame:

Observations

The link "Observations" refers to a page where some remarks about the package and the required bandwidth are made. Also some examples are included in that page.

Select ping value

The links in the sentence "Select ping value: ..." can be used to select the type of the roundtrip value. The emphasized type denotes the current type. The following ping value types can be selected:

min
Display the minimum ping values.
avg
Display the average ping values.
max
Display the maximum ping values.
all
Display all the ping values: these are the value types, described above, using the format: min / avg / max.
lost
Display the percentage package lost
.

Overview tables

In these tables an overview is presented of the net test results between the @[HOSTS_TITLE] hosts. This is done for the time stamp mentioned in the first table header. The tables can be presented in the forms described below.

Load of the host.
They are presented in a table, containing one row with the load values of all hosts.
The hyperlink in the caption of this table, entitled "Load" leads to the page where the load values are presented as function of the time.
Roundtrip (ping) [ms] between two hosts.
The roundtrip values between two hosts are presented in the table entitled "Roundtrip ... [ms]". The trace of the table is empty, because there are no roundtrip measurements done with the current host.
The host hyperlinks in the title row and title column can be used to load a roundtrip table with the values between the host in the hyperlink and the other hosts in the table as a function of the time, traveling from the current time stamp mentioned in this table to the history.
Throughput [Mbit/s] from a one-directional TCP connection.
The throughput values between two hosts are presented in the table entitled "Throughput [Mbit/s]". It has the same structure as the table with ping values, described above.
The host hyperlinks in the title row and title column can be used to load a throughput table with the values between the host in the hyperlink and the other hosts in the table as a function of the time, traveling from the current time stamp mentioned in this table to the history.

Color scale

This table presents the colors which are used to scale the three data series in the overview tables. Going from the minimum value to the maximum, these colors are determined by an interpolation in the series: blue, cyan, green, yellow en red. However, at pseudo-color displays the interpolation is limited to the colors displayed in this table. Every data series have its private scaling. The maximum of the load values is minimal 2.

A gray, blank field in one the tables implies that the corresponding value could not be obtained for one or other reason.

Cookies

The current state of the tables with net performance results are stored at your local disk, but only after your authorisation, in the so called cookie file. This implies that the next time you open this page the last accessed table will be reopened. The data are stored in your cookie file for 30 days. Each time you reopen this file this period will be reset.

The following parameters are stored:
