Dynamic Latency management for IP telephone

Abstract

A method for dynamically reducing latency over a communications network independent of the Real Time Protocol. The method including determining the completion of processing of a next data block and the determination of the number of samples remaining in a queue of a consuming device of the next data block. Without knowing the latency of the system a determination is made on the variability based on the number of samples remaining in the queue of the consuming device. A determination is then made as to whether the remaining number of samples in the queue of the consuming device can be reduced based upon the variability and if so reducing the queue of the consuming device.

Description

technical field [0001] The present invention relates to voice over Internet (VoIP) telephony latency and, more particularly, to management technology methods for reducing latency of VoIP telephony. Background technique [0002] The science of converting sounds into electrical signals, sending them, and converting them back to sound is called telephony (i.e. the science of the telephone). The term is often used to refer to computer hardware and software that perform functions traditionally performed by telephone equipment. [0003] Internet telephony generally refers to communication services - voice, fax and / or voice messaging applications - over the Internet rather than over the Public Switched Telephone Network (PSTN). The basic steps involved in initiating an Internet telephony call are the conversion of the analog voice signal to digital format, and the compression / conversion of the signal into Internet Protocol (IP) packets for transmission over the Internet; the proce...

Problems solved by technology

However, none of these approaches are effective in determining one-way latency, since latency can be very asymmetric between two network nodes
