Interface, method and computer program product for controlling the transfer of electronic messages

Abstract

The present invention provides an interface for controlling the transfer of electronic transaction messages between a first financial institution and a plurality of switches distributed amongst a plurality of switch sites, wherein the first financial institution and the plurality of switches are connected via a data communications network, the interface comprising communication circuitry, processing circuitry and memory storing the operational status of each switch site, wherein the communication circuitry is operable to transmit a test message to one of the switch sites over the data network if no transaction message has been received from that switch site for a predetermined time, and in response to the test message, the communication circuitry is operable to receive an echo of the test message from the switch site; wherein the processing circuitry is operable such that if the echo is received within a defined time then the operational status of the switch site is set as operational and if the echo is not received within the defined time then the operational status of the switch site is set as not operational; whereby in the event that the operational status of the switch site is set to not operational, the processing circuitry is operable such that no electronic messages are transferred to the switch site.
