net_load(1)
NAME
net_load - Calculate the load values at the connection links and nodes of a
net
SYNOPSIS
net_load |
[Option [...]] Site1:Site2

net_load |
-file ArgumentsFile [Option [...]]
[Site1:Site2 [...]] |
DESCRIPTION
The script net_load calculates the load values at the connection links
of a net when artificial traffic is generated at the sites or nodes of the net.
Also the load values at the sites or nodes of the net, induced by the passing
traffic, is displayed.
Default the traffic is generated at all sites, however, the user can select also
specific sites or nodes, called targets where the traffic is generated.
It is also possible to define the destination targets who are receiving traffic
from a source target.
The traffic in the net is routed as follows:
- The traffic takes the shortest route between two sites.
- When routes between two sites are of equal length, the traffic is equally
distributed across these routes.
However, it is also possible to define a fixed route between two sites.
In that case this route is always used.
Please note that this perl(1) script does not contain platform
dependent methods and is therefore in principle platform independent,
because perl(1) is supported for many platforms.
OPTIONS

It may be multiple specified.
- -print_routes

- -route
SourceSite[:...]:DestinationSite
- Specify a fixed route from SourceSite to
DestinationSite along the network which all traffic between these
sites should follow.
This option may be multiple specified.
- -scale ScaleLoad
- Scale the load values with the specified value.
The default is 1.
- -skip SourceSite
DestinationSite[:...]
- Do not generate traffic for the specified target source from this source to
the specified target destination(s).
This option may be multiple defined.
It overrules the -test option.
- -targets Site1:Site2[:...]
- Specify the target sites where the traffic should be started and ended.
Default all the specified sites are used as target sites.
This option may be multiple specified.
- -test SourceSite
DestinationSite[:...]
- Generate traffic only for the specified target source from this source to
