DIS PDU Router

The DIS PDU Router also isolates the IP and port number addresses on the LAN from the WAN. It avoids complex IP address modifications, accommodating different WAN configurations. For example, a simulator and its associated DIS radio equipment may impact 20 or more hardware items, each with its own IP address and port number. Let's say you're participating in a WAN simulation session that requires a new IP address and port combination. Instead of editing 20 or more network configurations, you only need to change a single setting.

DIS PDU Router provides hierarchical filtering for six levels. Filtering specifies which PDUs to accept when routing from the LAN to the WAN, automatically excluding unwanted PDUs. The DIS PDU Router filters for the following:

• Exercise ID: DIS PDU Router can only route PDUs matching the specified exercise IDs, with an option to route all exercise IDs.
• DIS family: DIS PDU Router can only route PDUs belonging to the specified DIS families, with an option to route for all families.
• Site/application: DIS PDU Router can only route PDUs from specified site/applications, with an option for all site/applications. Specify up to 64 site/applications.
• Entity range from datum: DIS PDU Router can only route PDUs (i.e., Entity State PDUs and any equipment associated with a platform) within a specified number of nautical miles from a specified datum point latitude and longitude. It can also accept entities regardless of range.
• Platform domain: DIS PDU Router can only route PDUs (i.e., Entity State PDUs and any equipment associated with a platform) that match the specified domain (i.e., land, air, surface, subsurface, space, and undefined domains up to 255). Users must separately enable each domain.
• Radio frequencies: DIS PDU Router only routes PDUs for transmitters operating within one of up to 32 specified frequency ranges, with an option to route all frequencies.

DIS PDU Router can also exclude any Radio Receiver PDUs, Intercom Control PDUs, or Signal PDUs.

The actual bandwidth savings depend on the DIS exercise's configuration. In particular, major savings usually impact local intercom traffic filtering not required by the WAN. The actual savings depend on the number of local intercom circuits available to filter and the amount of DIS traffic that those intercom circuits are generating.

A real world example might show a 41 percent reduction in the peak-per-second bandwidth and a 43 percent reduction in the average per-second bandwidth. A 40 percent bandwidth reduction is fairly typical.

DIS PDU Router introduces little extra latency. Typical latency values are 10 ms, but the actual value depends on the WAN's level of congestion.

To set up the DIS PDU Router, just select the appropriate check box or enter values when prompted. After specifying filter options, save them to a file for easy recall.

Remote agent control is fully automatic. The DIS PDU Router automatically transmits the local controller's filter options to the remote agent in five seconds. Users cannot remotely configure the remote agent because it derives its filter settings from the local controller.

The local controller communicates with the remote agent using the WAN DIS IP address and port number. It uses a nonstandard DIS PDU Type, Family, and Exercise ID of 199.

No, you can use the local controller by itself to filter the PDUs from the local LAN to the WAN. The remote agent optionally allows you to control filtering at the remote end of the WAN.
