Abstract: In some embodiments, the invention may include a combination of real-time packet detection, processing and routing. When implemented in a distributed architecture, such systems can yield a low cost, high availability and/or secure network capable of switching real-time data and delivering the quality of service expected in mission critical systems.

Abstract: A network gateway, method and computer program product for providing data translation between dissimilar networks capable of communication at a unit includes a translation element and a routing element. The translation element is configured to translate packet data between different formats of an internal network and a shared network via which the unit is capable of communication with an external unit. The routing element is configured to dynamically update routing tables for routing the packet data based on the content of the packet data. A routing element, apparatus and system for providing intercom services for communication between units are also provided, thereby providing an increased ability to share resources between units.
