Cannot ping sat #9

Open avar99 opened 1 month ago

avar99 commented 1 month ago

Hi, i would like to ping the sat entity from the gateway or the sat-terminal, with a "total delay" that is the double of the propagation delay imposed by the network topology. However this look impossibile and i don't know how to do it. I want to do it because i would like to simulate an IOT network where the broker is on the SAT and the sat doesn't work only as a "reapeter" of the net. I don't know if it is possible or not. Trying to use a mesh topology with the opensand deploy, launching the entity, the profile file of the sat is not uplaoded on the machine indicated (but the the other two file are uplaoded normally) and I don't know why. Thank you for the answer Michele

Hi,

Trying to reach the satellite has not been tested and is not an advertised feature of OpenSAND. You may want to think of OpenSAND as a black-box between terrestrial entities, for that matter.

However, you may be able to achieve that by using a regenerative satellite up to the IP level (check the options in the topology file) and associating a LanAdaptation and a TAP on the satellite. This is not intuitive as it should go in the "ISL" section of the satellite (check the infrastructure file), but by making the destination ID the same as the ID of the satellite, messages may find their route to the TAP.

As for the profile.xml file not being deployed, make sure you added one to the satellite as well as the regenerative topology requires that you provide one or it will not start.

Best of luck.
