money by publishing in this field without much regard to genuine need; but that temptation imposes a greater, not a lesser, responsibility on publishers and editors to attempt to fulfil a useful role.

This argument leads to a contradictory result that comp...

In this paper, we study atomic multicast, a fundamental abstraction for building fault-tolerant systems. We suppose a system composed of data centers, or groups, that host many processes connected through high-end local links; a few groups exist, interconnected through high-latency communication links. In this context, a recent paper has shown that no multicast protocol can deliver messages add...
