<p>The present invention relates to a communications network (60) comprising a plurality of network sites (agent provider A,B,...n). Such a network may include the Internet. Agent programs (agent A,B,C,N) are switched through the communications network (60) by reference to site addresses included in a site visit address list (to visit list) carried by each agent program. The network (60) has a number of network sites (agent service provider A,B,...n) which are service provider sites. Each service provider site includes an address registry (53) and data processing means (55) programmed to collect site address information in the address registry (53) from visiting agent programs. The data processing means (55) is further programmed to insert site address information from the registry (53) into the visit address list (to visit list) of succeeding agent programs (agent A,B,...n) which visit the site. By this means a distributed registry may be built up at the service provider sites of addresses which offer the same service or same category of service to visiting agent programs. <IMAGE></p> |
