We have implemented ALMI as a Java-based middleware package using JDK1.2 [#!jdk!#]. In the two experiment sets described below, we evaluate the performance of an actual operational group of ALMI nodes over both a WAN and a LAN. These two scenarios have fundamental differences; in a LAN environment most of the delay between two ALMI nodes is due to host processing while over a wide area network, delay is mostly due to transmission, propagation and queuing delay over the network.
