Abstract

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.

First claim

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 the amount of jitter in the communications network based on a measured queue depth in the dejitter buffer relative to a plurality of different adjustable thresholds.

2 . The remote device of claim 1 where the amount of jitter is measured based on a current position of each of the plurality of different thresholds.

3 . The remote device of claim 1 where the dejitter buffer includes a plurality of queues.

4 . The remote device of claim 3 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.

5 . The remote device of claim 1 where the queue depth is measured relative to a first adjustable threshold independently of a measurement relative to a second adjustable threshold.

6 . The remote device of claim 5 where the queue depth is measured based on the difference between a location in the queue of the first adjustable threshold and a location in the queue of the second adjustable threshold.

7 . The remote device of claim 1 where each adjustable threshold is adjusted based on detection that the respective threshold is crossed.

8 . The remote device of claim 1 where the jitter is measured based on a determined interpacket gap.

9 . The remote device of claim 1 where the processor is configured to adjust at least one threshold based on a delay.

10 . The remote device of claim 9 where the processor is configured to adjust at least one threshold without the delay.

11 . A method of measuring current jitter in a queue of a remote device in a distributed access architecture of a communications network, the method comprising:
measuring a queue depth in the dejitter buffer relative to each of a plurality of different adjustable thresholds; measuring current jitter using a position in the queue of each of the plurality of different adjustable thresholds.

12 . The method of claim 11 implemented in at least one of an RPD and an RMD.

13 . The method of claim 11 where the dejitter buffer includes a plurality of queues.

14 . The method of claim 13 where the amount of jitter is measured based on a measured depth of each of the plurality of queues relative to a plurality of adjustable thresholds associated with each queue.

15 . The method of claim 11 where the queue depth is measured relative to a first adjustable threshold independently of a measurement relative to a second adjustable threshold.

16 . The method of claim 15 where the queue depth is measured based on the difference between a location in the queue of the first adjustable threshold and a location in the queue of the second adjustable threshold.

17 . The method of claim 11 where each adjustable threshold is adjusted based on detection that the respective threshold is crossed.

18 . The method of claim 11 where the current jitter is measured based on a determined interpacket gap.

19 . The method of claim 11 where at least one threshold is adjusted based on a delay.

20 . The method of claim 19 where at least one threshold is adjusted without the delay.
