Automatic adjustment of buffer depth for the correction of packet delay variation

摘要

The size of a Jitter Absorption Buffer (JAB) is automatically changed in response to changes in network conditions. The JAB size is changed based on the fullness of the JAB and the recent variations in JAB depth. Automatic adjustment allows for a balance of providing adequate correction for Packet Delay Variation (PDV) while avoiding unnecessary increases in Absolute Packet Delay (APD) from the prolonged use of an oversized JAB. This abstract is provided as a tool for those searching for patents, and not as a limitation on the scope of the claims.
