Claims
- 1. A method for measuring a bandwidth of a signal path between a data source and a data recipient, comprising the steps of:sending a block of test data from the data source along the signal path to the data recipient and measuring a time required for the test data to be transferred to the data recipient; determining whether the measured time is at least a threshold value and, if the measured time is at least the threshold value, using the measured time to determine a measured bandwidth of the signal path; and transferring information from the data source along the signal path to the data recipient at a rate within the measured bandwidth; setting the measured bandwidth to a default value if an amount of delay exceeds a predetermined time, and wherein, if the measured time is at least the threshold value, the using of the measured time to determine a measured bandwidth of the signal path is delayed.
- 2. A method for measuring a bandwidth of a signal path between a data source and a data recipient, comprising the steps of:detecting whether the bandwidth of the signal path was previously determined; if the bandwidth of the signal path was not previously determined, sending a block of test data from the data source along the signal path to the data recipient and measuring a time required for the test data to be transferred to the data recipient; if the bandwidth of the signal path was previously determined, determining whether the measured time is at least a threshold value and, if the measured time is at least the threshold value, using the measured time to determine a measured bandwidth of the signal path; and transferring information from the data source along the signal path to the data recipient at a rate within either the previously determined bandwidth or the measured bandwidth.
- 3. A method according to claim 2, further comprising a step of:setting the measured bandwidth to a default value if an amount of delay exceeds a predetermined time, and wherein, if the measured time is at least the threshold value, the using of the measured time to determine a measured bandwidth of the signal path is delayed.
