Abstract : Delays are studied which are due to link outages experienced in sending data through a communication network. Error-correcting techniques ensure that all data are effectively transmitted without error through a link, but delayed when the link is not functioning correctly. One source of data and one link for data is assumed. A data handling logic is adopted at the nodes which permits the use of all links (if desired) in a network. The use of redundant links to reduce delay was investigated by means of a computer simulation program. The link behavior assumed for this program is that obtained from measurements of two HF RTTY links. Theoretical approximations for delay are obtained which indicate the importance of the minimum cut set and minimum path length. Simulation results are in close accord with these approximations.
