Low Latency Message Switching and Precedence Handling

Military messaging systems, and other messaging systems with time-critical operational requirements, such as Aviation (AMHS), require high-precedence messages to be submitted, transferred and delivered very quickly.

Isode have examined how messages can be handled to achieve message switching times of a few hundred milliseconds, for both low and high volumes of traffic. The importance of permanent associations as a way of avoiding delays in opening a connection is described, and consideration is given to precedence-handling, describing techniques that ensure high-precedence traffic gets optimum (low) latency. We can explain why message pre-emption is not a useful approach and why DiffServ is important when there are bandwidth limitations.
