The most fundamental question when designing any network is how to
connect the network elements together. The network topology defines
such crucial parameters as latency, throughput, ease of routing, and
fault tolerance. We present our evaluation of various
network topologies, including stars, rings, n-dimensional meshes, hex
meshes, and chordal rings. We derive upper limits on the performance
of each; this analytical model is general enough to apply to many
different types of networks, including Fibre Channel, ATM, and even
Ethernet networks. We then compare the different topologies and discuss
where each particular topology is appropriate.
