Abstract
In this paper we discuss new synchronization algorithms for Parallel and Distributed Dis­
crete Event Simulations (PDES) which exploit the capabilities and behavior of the underlying
communications network. Previous work in this area has assumed the network to be a Black
Box which provides a one­to­one, reliable and in­order message passing paradigm. In this work,
we utilize the Broadcast capability of the ubiquitous Ethernet for synchronization computa­
tions, and both unreliable and reliable protocols for message passing, to achieve more efficient
communications between the participating systems.
We describe two new algorithms for computation of a distributed snapshot of global reduction
