Abstract
A system and method for maintaining reliable in-order event distribution using multicast are described. A trigger event is sensed and a multicast payload containing a plurality of queued events and a packet sequence number in response to the trigger event is created. Further, a current multicast packet is transmitted to at least one receiving device, the current multicast packet containing the multicast payload. The multicast packet is received from the transmitting device and a transmission count of each of the plurality of queued events is examined. In addition, a plurality of current queued events of the plurality of queued events and a plurality of missed transmission queued events of the plurality of queued is processed.
