Abstract

To permit communications between devices using different communication protocols, a mapping device is connected to one or more communication networks, and stores associations between communication addresses as dynamic address mappings. A dynamic address mapping is associated with an initiator address (from which the communication is initiated) and a recipient address (to which a communication is initially addressed) and minimally contains a final address (to which a communication is finally routed). A new dynamic address mapping can be created in response a request, typically from a communication initiator. Communications from the initiator address to the recipient address are routed to the final address, with appropriate format conversion if the protocol of the final address is different to that of the initiator address. A reply address may also be stored in a dynamic address mapping for return communications, and a reply mapping may be automatically generated to map the reply address to the initiator address.

Claims

1. A method of determining the routing of a communication between an initiator and a recipient, comprising:

storing, in an electronic memory apparatus, associations between communication addresses as address mappings, wherein

(i) each address mapping

(a) is stored such that it is associated with an initiator address from which a communication is initiated and a recipient address to which the communication is addressed,

(b) is retrievable using a combination of both the initiator address and the recipient address, and

(c) stores an identifier for at least one final address to which the communication is to be delivered; and

(ii) an address mapping is dynamically created in response to an edit request from the initiator; and

determining, using an electronic processing apparatus, a final address for a communication from an initiator address addressed to a recipient address, from the final address identified by a stored address mapping retrieved using a combination of the initiator address and the recipient address.

2. The method of claim 1, wherein the determining comprises:

receiving a lookup request specifying the initiator and recipient addresses;

searching for an address mapping associated with the initiator and recipient addresses specified by the request; and

providing the final address identified by an address mapping associated with the initiator and recipient addresses specified by the request, if such an address mapping is located.

3. The method of claim 1, wherein the edit request specifies the initiator address and the final address for the mapping to be created, and

the recipient address is specified by the edit request or is determined automatically using a predetermined algorithm.

4. The method of claim 3, wherein the recipient address is determined automatically by allocation from a pool of addresses.

5. The method of claim 4, wherein the recipient address is de-allocated when such allocation is no longer required, so that the address is available for re-allocation from the pool of addresses.

6. The method of claim 1, wherein at least one address mapping further identifies a reply address, the reply address being a communication address which is addressable by the same protocol as the final address.

7. The method of claim 1, wherein at least one address mapping created in response to an edit request identifies a reply address which is addressable by the same protocol as the final address, and wherein the reply address is specified by the edit request, or is determined automatically using a predetermined algorithm.

8. The method of claim 7, wherein the reply address is determined automatically by allocation from a pool of addresses.

9. The method of claim 8, wherein the reply address is de-allocated when such allocation is no longer required, so that the reply address is available for re-allocation from the pool of addresses.

10. The method of claim 1, wherein when an address mapping is created, a corresponding reply mapping is automatically created, wherein the initiator address of the reply mapping is set to the final address of the created address mapping, and the recipient address of the reply mapping is set to a reply address of the created address mapping or is determined automatically using a predetermined algorithm

11. The method of claim 10, further comprising setting the final address of the corresponding reply mapping to the initiator address of the created address mapping.

12. The method of claim 11, wherein the creation of a corresponding reply mapping comprises generating a reply edit request and creating the corresponding reply mapping from the reply edit request.

13. The method of claim 12, wherein the generated reply edit request comprises a reply address set to the recipient address of the created address mapping.

14. The method of claim 1, further comprising modifying an address mapping and/or a corresponding reply mapping in response to a modify edit request.

15. A method of claim 14, wherein modifying a corresponding reply mapping comprises

generating a reply modify edit request having an initiator address set to the final address of the modified address mapping, and a final address set to the initiator address of the modified address mapping;

and

modifying the corresponding reply mapping in response to the reply modify edit request.

16. The method of claim 15, wherein the reply modify edit request comprises a reply address set to the recipient address of the modified address mapping.

17. The method of claim 1, further comprising associating a single address mapping with multiple initiator addresses and/or multiple recipient addresses.

18. The method of claim 1, wherein an address mapping identifies multiple final addresses and/or multiple reply addresses, and

a single final address is selected from the multiple final addresses using a predetermined algorithm, and/or

a single reply address is selected from the multiple reply addresses using a predetermined algorithm.

19. The method of claim 1, wherein the final address and the initiator address of an address mapping have different communication protocols, and/or the final address and the initiator address of a reply mapping have different communication protocols.

20. A method of routing a communication, comprising:

storing associations between communication addresses as address mappings, wherein each address mapping

(i) is stored such that it is associated with an initiator address from which a communication is initiated and a recipient address to which the communication is addressed and which is addressable by the same communication protocol as the initiator address,

(ii) is retrievable using a combination of both the initiator address and the recipient address, and

(iii) stores an identifier for at least one final address to which the communication is to be delivered, and

wherein at least one address mapping is dynamically created in response to an edit request from the initiator;

determining a final address for a communication from an initiator address addressed to a recipient address, from the final address identified by a stored address mapping retrieved using a combination of the initiator and recipient addresses; and

routing the communication from the initiator address to the final address.

21. The method of claim 20, wherein when an address mapping is created in response to an edit request, the edit request specifies both the final address and the initiator address of the address mapping, and the recipient address of the address mapping is specified in the edit request or is determined automatically using a predetermined algorithm.

22. The method of claim 20, wherein at least one address mapping further identifies a reply address, the reply address being a communication address which is addressable by the same protocol as the final address.

23. The method of claim 20, further comprising automatically storing an association between a final address and both an initiator address and a recipient address as reply mapping, wherein the initiator address of the reply mapping corresponds to the final address of the address mapping, and the recipient address of the reply mapping is a communication address which is addressable by the same protocol as the initiator address of the reply mapping.

24. The method of claim 23, wherein the final address of the reply mapping is set to the initiator address of the created address mapping.

25. The method of claim 23, wherein the reply mapping specifies a reply address which is a communication address which is addressable by the same protocol as the final address of the reply mapping.

26. Apparatus for routing a communication, the apparatus comprising

mapping means adapted to communicate with one or more communication networks, the mapping means having a data store containing associations between communication addresses as address mappings, wherein each address mapping

(a) is stored such that it is associated with an initiator address from which a communication is initiated and a recipient address to which the communication is addressed,

(b) is retrievable using a combination of both the initiator address and the recipient address, and

(c) stores an identifier for at least one final address to which the communication is to be delivered;

and

search means responsive to a lookup request specifying a combination of an initiator address and a recipient address, for searching the data store for an address mapping associated with the specified initiator and recipient addresses, and for identifying a final address from that address mapping if such an address mapping is found.

27. The apparatus of claim 26, wherein the mapping means comprises means for creating an address mapping in the data store in response to an edit request.

28. The apparatus of claim 26, further comprising a protocol converter for converting the protocol of the communication if the protocol of the output final address is different from the protocol of the initiator address.
