Testing STANAG 4406 Military Messaging Over IP Differentiated Services

IP Differentiated Services (DiffServ) is a standardized Internet approach for dealing with different classes of traffic. Isode has added support for differentiated services to its M-Switch X.400 product, so that its priority handling (which supports standard X.400 three level priority, and the STANAG 4406 military messaging six level priority) can utilize differentiated services at the IP level. The goal of this support is to enable higher precedence messages to get preferential service at the network level, and to better meet the goals of military messaging users. The theoretical case is argued in the Isode white paper Sending FLASH Messages Quickly: Techniques for Low Latency Message Switching and Precedence Handling.
