Direct Message Protocol (DMP)

DMP is an MTA to MTA protocol, and is interoperable with STANAG 4406, S4406. This allows the exchange of messages with the strategic domain. This implies that it is also possible to have multi-hop connections using different protocols on different hops. DMP is very bandwidth-efficient. This allows DMP to be used for time-critical messages even when using low-bandwidth channels (e.g. HF radio).

The DMP uses existing bearers (such as IP), and only puts moderate demands on processing power. This allows DMP to be implemented on almost any platform, including hand-helds and laptops.

History

The Direct Message Protocol is currently being proposed as a supplement to STANAG 4406 Annex E (see S4406).

Capture Filter

You cannot directly filter DMP protocols while capturing. However, if you know the UDP port used (see above), you can filter on that one.
