IP/Transport

These are the options offered by the IP and Transport modes:

Parameter setting, IP/Transport

  • "IP path length": the time required to trace a packet increases with proportionally to this figure.
  • "Show the frame": it tells you whether the Ethernet frame is visible during the simulations.
  • "Default packets path": it tells you if, by default, the packets follow the physical way (Ethernet way) or if they are transported from a router to another one (IP route).
  • "ARP cache's TTL": refers to the number of IP packets emitted before the dynamic entries are deleted from the ARP caches.
  • "Waiting time for ping if failure": refers to the amount of time before a message is displayed when a "ping" fails. This waiting time starts after the end of simulation.
  • "IP packet's TTL": maximum number of jumps allowed for an IP packet.
  • "Show Internet's component demonstration": it indicates whether the Internet component displays a "mini demonstration" in non-manual simulations.
  • "Hide ARP in IP mode by default": it indicates if, by default, the exchanges related to ARP are hidden during the simulations carried out in the IP mode. You can use this option, together with the "show the frame" one to completely hide the Ethernet layer in the IP simulations.
  • "Show icons on stations": if this box is unchecked, there is no displaying of the icons which tell you if operations such as translations, routing, or filtering are carried out by a station. Thus, you can choose longer names for the stations.
  • "Show icons on routers": same thing as for the preceding option, this time concerning the routers.
