Abstract

A data messaging system includes a first Internet Protocol (IP) switch that includes a processor. The data messaging system also includes a first gateserver coupled to the first IP switch and coupled to a second IP switch. The data messaging system includes a second gateserver that is coupled to the first IP switch and to the second IP switch. The data messaging system further includes a first gatekeeper coupled to the first IP switch. The first gatekeeper is adapted to detect a failure of the first gateserver and to route data to the second gateserver in response to detecting the failure.
