R&S®MMHS: military command and control in line with the STANAG NATO standard. The R&S®MMHS military message handling system covers. MMHS (Military Message Handling System) is a profile and set of extensions to X. for messaging in military environments. It is NATO standard STANAG Switch ACP Gateway to STANAG & MMHS over SMTP. ACP is an older military messaging protocol, which remains in widespread use along with a .

VLF radio has the advantage that stanag 4406 will penetrate below the surface for a moderate distance, and so can be used by a submarine without surfacing. The third, optional, use is an important feature of the Isode solution. In some situations, store and forward messaging is useful, for example to send key information e. Annex E defines protocols and procedures for integrating an X. When ships are deployed as part of a task force, communication will generally go to the stanag 4406 command stanag 4406 usually a larger surface unit with the necessary command, control and communication equipment.

It will often be desirable or essential to have radio silence EMCONstanag 4406 to retain the ability to listen and to receive messages. When MTAs communicate over a high speed network they use the X. HF Radio is important for military communications, because of its effectively unlimited range. The MTA will enable local message distribution and give a natural external interface.

In general, a ship would have stanag 4406 a number stanag 4406 potential internal message recipients, and the external message communication needs to be connected with the internal messaging infrastructure. A separate product page gives a more general overview of M-Store X. Maximum support of messages direct from originators is desirable. MConsole’s tracking of messages is shown in the screenshot below.


These need to stanag 4406 managed, and shore systems will be most effective if they understand the current state of communication, a situation also relevant to the previous scenario. Submarines may make use of higher bandwidth channels when they are on the surface.

The diagram above shows the protocol stack used over HF Radio. Isode provides three server products that can be stanag 4406 to fulfill a number of the stanag 4406 roles outlined above. It is often appropriate to provide special purpose applications using an MMHS infrastructure.


Isode’s products for a military messaging solution feature:. It serves as an intermediary between User Agents and the Message Transfer Agent, accepting delivery of messages on the user’s behalf and storing them for subsequent retrieval. To support multicast, multicast support is necessary stanag 4406 all of the routers used. This relay needs to be fully automated, and not require manual intervention at the first field unit. Both stanag 4406 are shown below:.

R&S®MMHS STANAG 4406-Based Military Message Handling System

This is achieved by planned timing of communication status, which is shared between submarine and shore. Exchange and do not provide X. This product includes an X. The stanag 4406 so far has primarily considered stanag 4406 of a single constrained bandwidth communication channel. These are summarized below and will be illustrated in the scenarios described subsequently.

This section considers a number of scenarios where the technologies described here stanag 4406 important. The army has similar requirements. It is not intended to be an exhaustive list.

ACP is an end to end protocol, that can map onto various underlying transport mechanisms described later. HAG products generally use X.


This reflects a typical configuration, as in general the MTA will not be connected directly stanag 4406 a satellite router. HF Radio and Satellite.

Isode’s stanag 4406 messaging solution is stanag 4406 on the web page: The above scenario shows use stanag 4406 Satellite to reach the command ship and broadcast HF high frequency radio for communication with the other units in the task force. This end to end protocol is based on the X. When submarines dive below the level of VLF penetration, they will be out of all communication, and so this leads to three basic states: Technical Architecture and Back-end Features]. When both channels are open, use of Satellite may be preferred higher bandwidth or use of HF radio lower cost stanag 4406, or a more complex preference dependent on messaging load.

The Audit Database also enables tracking of messages, delivery reports and inter-personal notifications read receipts.

Stajag Messages often need to be transferred over low bandwidth networks, stanzg stanag 4406 HF Radio and Satellite Networks. It is particularly important for High Grade messaging, where features of X.

There are a number of basic stanag 4406 challenges that arise from military messaging deployments, stanag 4406 of which are particularly relevant to constrained communications channels. Multicast can be used for communication from the command ship to the other ships.

An example of statistics is given in the following screenshot that shows an analysis of message latency based on message precedence. Further details in the Isode whitepaper [ACP
