Apparatus and method of compensating for clock frequency and phase variations by processing packet delay values

An apparatus, comprising:

• a statistical parameter determination module configured to determine:
• a value of a first parameter of a statistical parameter type based on a first plurality of packet delay values;
• and
• a value of a second parameter of the statistical parameter type based on a second plurality of packet delay values determined subsequent to the first plurality of packet delay values;
• the statistical parameter determination module configured to send a signal to a network rearrangement detection module such that the network rearrangement detection module detects a network rearrangement based on the value of the second parameter of the statistical parameter type being different from the value of the first parameter of the statistical parameter type by at least a first threshold;
• the statistical parameter determination module being implemented in at least one of a memory or a processing device.

An apparatus, comprising:

• a first module configured to detect a network rearrangement based on:
• a value of a first parameter of a first statistical parameter type that was determined based on a first plurality of packet delay values;
• a value of a second parameter of the first statistical parameter type that was determined based on a second plurality of packet delay values determined subsequent to the first plurality of packet delay values;
• a value of a first parameter of a second statistical parameter type that was determined based on the first plurality of packet delay values, the second statistical parameter type being different from the first statistical parameter type;
• and
• a value of a second parameter of the second statistical parameter type that was determined based on the second plurality of packet delay values,
• the first module being implemented in at least one of a memory or a processing device;
• and
• an adjustment module configured to compensate for a phase variation of an electronic component corresponding to a difference between the value of the second parameter of the first statistical parameter type and the value of the first parameter of the first statistical parameter type if the network rearrangement is detected.
