Optimization of a topologically tree-based local area network (Q1117827)

In search of the most versatile local area network (LAN) available, we discovered a topologically tree-based LAN proposed by \textit{G. J. Lipovski, A. Goyal} and \textit{M. Malek} [Lookahead networks, AFIPS Proc. Nat. Comput. Conf. 51, 153-165 (1982)] to be most adaptable to the various purposes and applications desirable within a LAN environment. In addition to versatility, the network considered here offers the advantages of a high degree of fail-softness - and thus reliability - simplicity in the access protocol, high bandwidth utilization, low-delay characteristics, and modularity - which ensures future expansion and ease of installation and maintenance. Questions relating to features critical to the optimal design and use of such a LAN are analyzed and answered. Key mechanisms investigated include fanouts and partitions, delays and degradation.
