Abstract

Systems and methods for effectuating transparent transaction processing takeover in a communications system. An active queue computer facilitates the processing of transactions from a first network layer using an internal active queue. One or more stand-by queue computers shadow the processing of the active queue computer by maintaining internal stand-by queues that are continually synchronized with the active queue. Upon detecting that the active queue computers has entered a failure state, a stand-by queue computer takes over the processing of pending transactions, preferably including those that are currently in the active and stand-by queues. The stand-by computer, now in pseudo-active mode, may return active processing to the former active queue computer after rebooting, may request a network address change to takeover active processing on the stand-by queue computer, or may facilitate the transferring of active status to an additional computer.
