 Starting simulation:
 - Setup the instance of this simulator by:
-  - ./simulator.sh compose IPGW IPSUBNET I IPVES IPPNFSIM IPFTPS IPSFTP
-	where Gw and subnet will be used for docker network

-	where IPVES is the address of the VES collector
-	where IPPNFSIM, IPFTPS, IPSFTP are the addresses for containers
-	e.g. ./simulator.sh compose 10.11.0.65 10.11.0.64 3 10.11.0.2 10.11.0.66 10.11.0.67 10.11.0.68

+    where TYPEFILESERVER is the type of fileserver, i.e., FTPS or SFTP
+	where PORTSFTP, PORTFTPS are the SFTP and FTPS ports
+	e.g. ./simulator.sh compose 10.11.0.65 10.11.0.64 3 http://10.11.0.69:10000/eventListener/v7 10.11.0.2 10.11.0.66 ftps 2001 2002 10.11.0.67 10.11.0.68
 
 - Setup environment with "./simulator.sh start". It will download required docker images from the internet and run them on docker machine
 - To start the simulation use "./simulator.sh run-simulator", which will start sending PNF registration messages with parameters specified in config.json    {TODO, might not be needed}
