QNET is a software package for performance analysis of queueing
networks. It uses Brownian approximations, which are based on heavy
traffic limit theory.

QNET is copyrighted by Jim Dai and J. Michael Harrison. The current
version, QNET 1.1, is available free from the authors. You are
encouraged to use QNET in your teaching and research. However, you
must NOT use QNET for any commercial purpose.

The current version of QNET consists of three programs: gjn, mcn, bnet.
"gjn" converts data for a _generalized _Jackson _network into Brownian 
network data. "mcn" converts data for certain _multi_class _networks
into Brownian network data. "bnet" is an engine which computes the 
stationary distribution for the corresponding Brownian network model. 
Detailed documentation of these programs is included in the package.

QNET 1.1 is written in C. It is  known to compile on the following
platforms: SUN SPARC (cc and gcc), DEC5000 and DEC3100 (cc and gcc),
HP9000 (cc), 386/486PC (turbo C and djgpp), IBM  RISC6000 (cc and xlc),
Symmetry-DYNIX (cc and gcc), NeXT (cc). Porting to other platforms
should be straight forward.
