Abstract
A method for sensing and regulating the level of synchronization between a file of audit blocks generated in a primary host for transfer to a secondary host. The audit files in a primary host are divided into audit blocks which are each identified with an audit block serial number. The individual audit blocks are transmitted through a network from a primary host to a secondary host wherein a tracker mechanism monitors the difference between the number of received audit blocks and the number of generated audit blocks residing at the primary host waiting to be transferred. When the disparity between the audit blocks received and the generated audit blocks waiting to be transmitted reaches a certain critical level, the tracker mechanism will initiate an advance speed up program to expedite the transfer in order to bring the primary and secondary audit files into greater synchronism. Further, the acknowledgment level can be set to indicate the number of audit blocks received in the secondary host for information back to the primary host and the acknowledgment level can be utilized in order to preset a critical value which will indicate that the speed up transfer operation should be initiated.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
