How to Untangle Network Topologies

A topology, which is the pattern of interconnections among nodes, influences a network's cost and performance. While commercial networks move toward low cost solutions, industrial networks must concentrate on rugged, heavy-duty solutions for multiple environments.This is achieved by using stronger signal integrity and heavier shields in the physical media.
