%X While special chips for message transfer in
multi\-transputer machines do not yet exist, there are
several software solutions which may be used. Dynamic link
reconfiguration is fastest but requires additional switching
hardware and a sophisticated common bus to control requests
from all network nodes. Through\-routing of messages via the
network is slower but the method is applicable to any
transputer network. This paper makes a comparison between
two through\-routing solutions for distributed message
passing and shows how the parameters of a software
implementation influence the communication throughput.
Several conclusions about the improvement of particular
through\-routing software are made and the results of the
experimental performance evaluation under different
conditions are given.
