Re: [Omnetpp-l] TSNsched problem

[Levente Mészáros]

Can you check if the output.json file is produced? Maybe your current working directory should be set to where it is.

Dear all:

I'm using inet 4.4 TSNschedGateScheduleConfigurator , i was able to deserialize the input and the constraint was met, but i met with this problem

How can i solve it?

When I change the output file name to “-TSNeched-output.json”in TSNschedGateScheduleConfigurator

It generate the output.json,but ran with the above problem.

When I change the output file name to “output.json”in TSNschedGateScheduleConfigurator

it can't generate the output.json,and ran with this problem

which directory should i use? or it can be something wrong with the TSNsched?

There is a ClassCastException in your second screenshot, it seems to me that there is another problem under the hood.

I can't tell you what's wrong with your example from this information, but the way INET uses TSNsched is quite simple. INET produces an JSON file from the network configuration, which is then read by TSNsched when it is run as a command line tool. You can run the exact same command from your terminal that INET executes during the initialization of the simulation. The result is another JSON file, which is read by INET during the initialization phase of the simulation. Finally, INET configures all TSN related modules and applications according to the schedule computed by TSNsched.

Dear levy:

When I change the output file name to “output.json”in TSNschedGateScheduleConfigurator

i ran with the invehicle example in inet 4.4, this is the whole exception

Dear levy:

Should i need to set the TSNsched output file path?

You only need to set TSNSCHED_ROOT.

Try running the example under showcases/tsn/gatescheduling/tsnsched with doubling the packet interval in both the application settings and the scheduler parameter as shown in the following diff:

Dear levy:

I double the packet interval and  in both the application settings and the scheduler parameter

and it just can't simulating.

 I double the packet interval and  in both the application settings and the scheduler parameter,and use run as /omnet++ simulation and the simulating figure is not show

i use the command line opp_run omnetpp.ini

and shows the result

Try running the simulation from the command line as shown in the attachment.

Dear levy:

when i running on the inet/showcases/combiningfeatures/invechicle/, i ran the simulation on general  ethernet
i got the following error.

How can i parameterize the frontswitch module?
