The effect of noisy links is considered in the design of a computer communication network topology. Because of noisy links, and the consequent probability of bit error, additional network traffic in the form of acknowledgement packets and retransmission packets are generated which load the network. A topological design procedure for obtaining a minimum cost network is proposed which satisfies given constraints of overall network delay, maximum delay on a link, throughput and reliability. Traffic priority for different classes of traffic is also taken into consideration in the design. As expected, the network cost increases as the bit error probability of the links increases.
