ABSTRACT:
Redundancy is provided in a communication network including a plurality of nodes (114, 112, 106, 102) by a first node (114) receiving and storing (402) a message (210) in a first memory (202). The first node then transmits (404) the message to a first one of a plurality of second nodes (112), and removes (412) the message from the first memory after receiving an acknowledgment from any one of the plurality of second nodes. The first one of the plurality of second nodes receives (502) and stores (504) the message within a second memory (302) and stores (506) the message within a third memory (110) accessible to the plurality of second nodes. The first one of the plurality of second nodes transmits (508) the acknowledgment to the first node after storing the message in both the second and third memories.
