Method of measuring network jitter
Systems and methods for measuring the amount of jitter in a network providing data to a remote device in a distributed access architecture based on a measured queue depth in a dejitter buffer relative to a plurality of different adjustable thresholds.
1 . A remote device in a distributed access architecture of a communications network, the remote device operatively connected to a core providing data to the remote device, the remote device including a dejitter buffer and a processor configured to measure an amount of jitter in the communications network based on a measured queue depth in the dejitter buffer relative to a first adjustable threshold and a second adjustable threshold;
wherein said first adjustable threshold and said second adjustable threshold are adjusted based on said measured queue depth; and
wherein said amount of jitter is calculated based on a difference between said first adjustable threshold and said second adjustable threshold.
2 . The remote device of claim 1 where the dejitter buffer includes a plurality of queues.
3 . The remote device of claim 2 where the processor is configured to measure the amount of jitter based on a measured depth of each of the plurality of queues relative to a plurality of adjustable thresholds associated with each queue.
4 . The remote device of claim 1 where the queue depth is measured relative to said first adjustable threshold independently of a measurement relative to said second adjustable threshold.
5 . The remote device of claim 1 where each adjustable threshold is adjusted based on detection that the respective threshold is crossed by said measured queue depth.
6 . The remote device of claim 1 where the amount of jitter is calculated based on a determined interpacket gap.
7 . The remote device of claim 1 where the processor is configured to adjust at least one threshold based on a delay.
8 . The remote device of claim 7 where the processor is configured to adjust at least one threshold without the delay.
