Abstract: A technique is provided for translating one or more networked applications to act virtually as if operating at a node or communication point within a network simulation. The invention disclosed herein has aspects of both emulation and simulation, allowing an actual networked application code (herein called simply ‘application code’) and simulated models to interact with each other in any combination. However, one or more application codes are virtually translated such that they appear to the rest of the simulated model(s) or applications code(s) to be resident at a simulated node. This simulated node may be any node (fixed or mobile) of the simulation, and one or more application codes can be mapped to a single node. Although the preferred embodiment would be the case where simulated time is synchronized to real-time, accelerated or slower than real-time simulation can also be used with the invention.

Abstract: A system and method for network routing is provided where significant (those that impact optimal network routes) state changes of network components are considered. A set of optimal communication paths are generated for a number of actual and potential component failure scenarios. An optimal communication path is generated for each failure scenario. In addition, a method that enables continued communication using intermediate routing points and routing update propagation during periods of network non-convergence or congestion is disclosed.

Abstract: A system and method for congestion avoidance and load balancing for communication networks is provided. When a source host is sending information to a destination host and a need is detected for an alternate route, a masquerading host acts as the source host and sends the information to the destination along the alternate route. The data is sent in a manner that leads the destination to believe that the data came from the source. In this way, the destination will accept the data as valid. General network status data such as delay times, packet delivery failures, bandwidth information, link status, etc., is used to control and manage the masquerading servers, which are arranged in a rim. Message data may be replicated on each host in the rim or may be passed among the host, or may stem from outside the rim.
