[Show abstract][Hide abstract] ABSTRACT: In this paper, a parallel and fault-tolerant LAN (P FTLAN) with
dual communication subnetworks is presented to improve LANs'
reliability. Its function modes, technical characters, hardware and
software architectures, and some key implementation techniques such as
logical addresses and parallel mechanisms, are described in details. Our
prototype system and analyzing results suggest that the scheme presented
in the paper not only provides an effective approach to high reliable
LANs, but also can improve their performance greatly
