Load of Net Links

The load numbers at the connection links of figure 1 from the "about the package" document are calculated with the Perl script net_load which is platform independent. Perl is a powerful scripting language. There are source and binary distributions available to download for Unix, Win32 and Macintosh.

The net_load script tries to find all routes in a network, where traffic is generated with the following rules:

However, the user can also define its own routing at some or all nodes of the network.

When the routes are known, traffic can be generated at all or some nodes of the net to some or all other nodes. Also the traffic to generate can be selected by the user. Default traffic is generated between all sites situated at the nodes of the network. The load the traffic introduces at the connection links of the net is listed. It is calculated from the knowledge of the routes in the net.

The load numbers in figure 1 can be calculated for all platforms with the following command line.

perl net_load  -scale 10 A:B B:C B:E C:D D:E E:F F:A

Note that the command line "perl net_load" prints a usage message of the script.
