     Dr. C.J. Colbourn of  the  University  of  Saskatchewan
     will  speak  on  ``The Construction of Reliable Series-
     Parallel Networks''.

     ABSTRACT

     The design of reliable computer communications networks
     is  a  topic  of  significant  interest; many heuristic
     methods have been developed for producing reliable net-
     works.   Perhaps the most widely used measure of relia-
     bility is a probabilistic one: the probability that the
     network  remains  connected  in an environment of (sta-
     tistically independent) link failures.  In  this  talk,
     we  characterize the series-parallel networks which are
     most reliable with respect to this probabilistic  meas-
     ure.   Remarkably  enough,  the  most  reliable series-
     parallel networks have  a  simple  characterization  in
     terms  of  degrees; in particular, the characterization
     is independent of many  typical  reliability  estimates
     such  as  connectivity and diameter.  The characteriza-
     tion is derived by solving a recurrence relation giving
     the  number of connected subnetworks of series-parallel
     networks.
