DIS PDU Router

DIS PDU Router is an application that provides powerful DIS filtering capabilities in a LAN-to-WAN connection environment to significantly reduce bandwidth requirements. The application consists of two parts: the master unit and an optional freely distributable remote slave unit. The master unit controls this slave unit to filter at the remote end of the WAN.

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.

What kind of filtering does DIS PDU Router provide?

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:

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

What sort of bandwidth savings should I expect?

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.

What about latency?

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.

How complex is the setup procedure?

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.

What about controlling the slave unit?

Slave unit control is fully automatic. The DIS PDU Router automatically transmits the master unit's filter options to the slave unit in five seconds. Users cannot remotely configure the slave unit because it derives its filter settings from the master.

How does the master unit communicate with the slave?

The master unit communicates with the slave using the WAN DIS IP address and port number. It uses a nonstandard DIS PDU Type, Family, and Exercise ID of 199.

Do I have to use the slave unit?

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