What changes are likely in network technology?
At present there are many overlapping information networks (e.g., tele phone, telegraph, data, cable TV), and new networks are emerging rapidly (paging, personal communications services, etc.). Each of the current in formation networks is engineered to provide a particular type of service and the added value provided by each of the different types was sufficient to overcome the fixed costs of building overlapping physical networks. However, given the high fixed costs of providing a network, the eco nomic incentive to develop an integrated services network is strong. Furthermore, now that all information can be easily digitized the need for separate networks for separate types of traffic is no longer necessary. Convergence toward a unified, integrated services network is a basic feature in most visions of the much publicized information superhigh way. The migration to integrated services networks will have important implications for market structure and competition. The international te
