A system and method are provided for maintaining state synchronization between a primary device and a secondary device. The present method includes the steps of generating a sequence identifier in the primary device, attaching the sequence identifier to a message in the primary device, transmitting the message and the sequence identifier attached thereto to the secondary device, and storing the sequence identifier in the secondary device as a secondary sequence identifier. In addition, the method includes the step of comparing a secondary sequence identifier from the secondary device with the sequence identifier in the primary device to detect a lost message.
