ASTi's Model Builder software includes powerful embedded features that are critical to effective DIS traffic management at the AC-130U facility:

• Model Builder automatically assigns IP Multicast and IP Broadcast addresses for DIS radio and intercom packets based on pre-defined DIS exercise numbers
  
  
• DIS Intercom buses (both Crew / Instructor buses and Radio Server buses) are assigned to IP Multicast addresses for effective filtering (blocking) by their facility routers. This constrains all DIS intercom traffic to the AC-130U local network
  
  
• DIS Radios are assigned to Broadcast IP addresses so that they are passed through facility routers for long haul distributed exercises
  
  
• The user sets the IP address assignment by DIS exercise number using a text-based configuration file and simple one-line commands
