MEASUREMENT OF PACKET DELAY VARIATION

摘要

Packet communication systems, or networks, are commonly used for the conveyance of information for data applications. The receive rate of incoming packets vari es as congestion in the network causes variation in the amount of time for a packet to traverse the network before being placed into the JAB (Jitter Absorption Buffer). The disclosure contains methods for calculating a real time measurement of PDV (Packet Delay Variation). This real time measurement is useful as a metric on the quality of the service provided by the network or as a trigger for dynamic adjustment of the operation of equipment to optimize for current network conditions. Mo re specifically, the disclosure includes a method that uses variations in the buffer depth of the JAB to measure PDV. This abstract is provided as a tool for those searching for patents, and not as a limitation on the scope of the claims.
