A method of allowing egress network frames to bypass the buffer requirement of a checkpoint system. In one embodiment, the method includes the steps of examining a frame, or its attributes, to determine if it is a 'candidate frame' and if the frame is a candidate frame, allowing it to be released to the external network without an intervening checkpoint. In another embodiment, the candidate frame is one of a group comprising: any frame targeting a designated network interface; any frame of a designated protocol type; any frame sourced or destined from/to a designated address. In still another embodiment, the method includes the designation of scheduling follow-up checkpoints according to frame disposition to limit or reduce the effects of a fail-over (roll-back) disturbance.
