Method and computer programs for providing special processing of a communication sent across a communication network
First Claim
1. A method in a communication system for providing a special processing of a communication sent from a first user processor at a first location to a second user processor at a second location across a communication network, the second user processor having an address in a special address range assigned to user processors in the second location that require the special processing, the method comprising:
- programming a router at the first location to route the communication to a first special processor, in response to the address of the second user processor being in the special address range;
programming the first special processor to perform the special processing on the communication addressed to the second user processor and to perform one of encapsulating and re-addressing the communication to send the communication to a second special processor, the second special processor having an address that is not in the special address range, thereby allowing routine delivery of the communication to the second special processor.

Abstract
A router (101, 102) at a first location (161) is programmed (306) to route a communication to a first special processor (141), when an address of a second user processor (121) to which the communication is sent is in a special address range. The first special processor is programmed (308) to perform special processing on the communication and to perform one of encapsulating and re-addressing the communication to send the communication to a second special processor (142), the second special processor having an address that is not in the special address range, thereby allowing routine delivery of the communication to the second special processor. The second special processor is programmed (310) to perform inverse special processing on the communication, and to perform one of unencapsulating and re-addressing the communication allowing routine delivery of the communication to the second user processor.

13. A computer program for programming a special processor in a communication system for providing a special processing of a communication sent from a first user processor at a first location to a second user processor at a second location across a communication network, the second user processor having an address in a special address range assigned to user processors in the second location that require the special processing, the computer program comprising:
-
a first software element for programming the special processor to receive the communication addressed to the second user processor; and
a second software element 404 for programming the special processor to perform the special processing on the communication, in response to receiving the communication addressed to the second user processor, and to perform one of encapsulating and re-addressing the communication, and then to routinely deliver the communication to a second special processor, the second special processor having an address that is not in the special address range. - View Dependent Claims (14, 15)
