The principal investigators propose to use a quaÕitative                   approach to analyzing stability problems in local area networks/                These problems include ergodicity and nonergodicity, partial                    ergodycity, practical stability, shape of steady-state                          distributions (bistability property) and robustness.  In order to               make meaningful performance predictions, given the variability                  inherent in most local area networks, they plan to take a                       stochastic approach throughout the research.                                         They will define stability of a system in terms of a number                of properties, provide computable conditions for various kinds of               stabinity and apply their analysis to different types of networks               such as ALOHI-type, ETHERNET with exponential back-off                          algor>thms, token-passing computer networks, multiaccess system                 with conflict resolution algorithms, and exponential back-off                   protocols.                                                                           The outcome is intended to be a set of constructiwe                        algorithms for assessing the stability of computer systems and                  their networks, methods for improving stability, and algorithms                 for approximating`impoztant performance measures of some classes                of complex systems.
