We investigate the design of communication networks and algorithms for the dissemination of messages to multiple receivers in networks. Broadcasting (i.e., one-to-all), gossiping (i.e., all-to-all), and multicasting (i.e., some-to-some) represent three dissemination tasks we have addressed. The research has focussed on the design of networks with few lines that allow optimal time completion or on algorithms that allow near-optimal completion in arbitrary networks. We have recently turned our attention to multicasting, looking for efficent, virtual topologies that can support that task with minimal overhead. On another front, we have addressed problems of minimal networks that provide redundant paths between senders and receivers, thus providing some immunity to failures of sites or lines.
