Cost Metric Algorithms for Internetwork Applications

Abstract : The particular function of the Multi-Network Controller (MC) to be implemented for the l990 Unified Networking Technology Advanced Technology Demonstration addressed in this Independent Exploratory Development (IED) project is the final selection of a subnet in response to a Transmit Service Request. The architectural description of the MC defines databases and performance measures used by this IED effort. In FY88, initial conclusions about the applicability of neural networks, fuzzy set methods, cost/value functions, and expert systems were investigated and documented. A Real Time Expert System (RTES), using subroutines that implement the decision techniques described, was selected as the best method for experimentation. A transportable, embeddable RTES shell (CLIPS) was chosen, and implementation of subnet selection algorithms began. A follow-on IED effort for FY89 has been funded. An independent research effort for FY89 is also a spin-off of the FY88 IED effort, and is described in this report.
