Abstract:
1. A method of processing data received at a local system in response to polling a remote device, wherein the local system includes a local clock, said method comprising: sending a first poll to the remote device; receiving a response from the remote device to the first poll, said response to the first poll containing data and a time stamp indicating when the remote device responded to the first poll; for the data received in response to the first poll, computing a first time by using both a response receipt time that was derived from the local clock for a previous poll of the remote device and also the time stamp contained in the response to the first poll; comparing the computed first time to information that the local system stored in connection with the first poll, wherein said information that the local system stored in connection with the first poll was derived from the local clock; and determining how to process the data received in response to the first poll based on comparing the computed first time to said information that the local system stored in connection with the first poll.
