Abstract

The present invention relates to a communications network comprising a plurality of network sites. Such a network may include the Internet. Agent programs are switched through the communications network by reference to site addresses included in a site visit address list carried by each agent program. The network has a number of network sites which are service provider sites. Each service provider site includes an address registry and data processing means programmed to collect site address information in the address registry from visiting agent programs. The data processing means is further programmed to insert site address information from the registry into the visit address list of succeeding agent programs 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.

Claims

1. A communications network comprising:

a plurality of interconnected network sites,

switching means for routing one or more agent programs through the communications network by reference to site addresses included in a site visit address list carried by each agent ptogram; and

a network site including (i) an address registry, and (ii) data processing means programmed for collecting site address information in the address registry from visiting agent programs and further programmed for inserting site address information from the registry into the visit address list of succeeding agent programs which visit the site.

2. A communications network according to claim 1, wherein the data processing means is programmed to collect site address information which includes site addresses and visit flags indicating which addresses have been visited.

3. A communications network according to claim 1, wherein the data processing means is programmed to collect site address information which includes site addresses and unsuccessful flags indicating which addresses have been unavailable.

4. A communications network according to claim 1, wherein the network site including the address registry and data processing means constitutes one of a plurality of service provider sites.

5. A communications network according to claim 4, wherein the service provider sites are capable of launching an agent program into the network.

6. A communications network according to claim 5, wherein the service provider sites are self-service cash dispensing terminals.

7. A network site for connection to a communications network, the network site comprising

an I/O port for the communication of one or more program agents into the network site from the network and from the network site into the network;

an address registry; and

data processing means for receiving and processing one or more program agents visiting the network site and received through the I/O port, the data processing means being programmed to compare the addresses in the address list of a visiting program agent with addresses in the address registry both to update the address register and to update the address list of the visiting program agent.

8. A network site according to claim 7, wherein the data processing means is programmed to collect site address information which includes site addresses and visit flags indicating which addresses have been visited.

9. A network site according to claim 7, wherein the data processing means is programmed to collect site address information which includes site addresses and unsuccessful flags indicating unavailable addresses.

10. A method of routing one or more agent programs through a communications network comprising a plurality of interconnected network sites, and a switching unit for routing the agent programs through the communications network by reference to site addresses included in a site visit address list carried by each agent program, the method comprising the steps of:

collecting and registering site address information from the address lists of agent programs visiting a site in the network; and

inserting such address information in the visit address list of succeeding agent programs which visit the site.

11. A method according to claim 10, wherein the step of collecting and registering site address information includes collecting and registering site addresses and visit flags indicating which addresses have been visited.

12. A method according to claim 10, wherein the step of collecting and registering site address information includes collecting and registering site addresses and unsuccessful flags indicating which addresses have been unavailable.
