Hi Elemer,

We at MCC TF160 simulate the NW for mobile devices. For routing reasons we would like to run some PTCs on a different machine with different IP addresses.

Is it possible to distribute PTCs on different machines?

If yes, can I get a documentation and a simple example?

Regards and thanks for any hint,
Olaf @ MCC TF160

Hi Olaf, sure thing;

start the main controller on Host1 with IPAddress1

./mctr_cli  ConfigurationFile.cfg

The configuration file may contain some parameters relevant to the main controller , e.g. TCP port to be used for MTC-PTC communication,
see refguide 7.11. [MAIN_CONTROLLER] (Parallel mode)

this will display the port on which the main controller will be listening:

...Listening on IP address IPAddress1  and TCP port 46308

Create mtc:

cmtc
Waiting for HC to connect...

then start the host controllers/PTCs in subsequent consoles of Hosts2 to n :

Host2:

./myExecutableBinary   IPAddress1  46308

(port has to match the above, and no config file here)

:
:
Hostn:

./myExecutableBinary   IPAddress1  46308

then start mtc in the first console:

smtc

Distribution of the PTCs overs hosts can be influenced by config file sections
[COMPONENTS] and [GROUPS],

see refguide:

7.9. [GROUPS] (Parallel mode)
7.10. [COMPONENTS] (Parallel mode)

and also by parameters of the create operation, see language standard
21.3.1 The Create operation

N.B. ttcn3_start cannot be used in this layout.

I hope this helps.

Best regards
