The TORA algorithm. |

Former ISR Associate Research Scientist M. Scott Corson, along with Vincent Park of the Naval Research Laboratory, have been issued US Patent #6,628,643 for technology invented during Corson's tenure with ISR. The patent is titled, "A Method for Eliminating the Requirement for Synchronized Clocks in Distributed Routing Approaches that are Dependent on the Temporal Ordering of Events."
The TORA (Temporally Ordered Routing Algorithm) algorithm is well-suited for operation in a relatively dynamic or bandwidth-constrained networking environment, for example a mobile wireless networking environment. It executes distributedly, provides loop-free routes, provides multiple routes to alleviate congestion, establishes routes quickly so they may be used before the topology changes, and minimizes communication overhead by localizing algorithmic reaction to topological changes when possible to conserve available bandwidth and increase scalability. TORA's design is based largely on the notion that high reactivity and bandwidth conservation are of greater importance than routing optimality.
