Benefits of technology

"The patent describes a method and apparatus for managing voice traffic in a data network. The method involves detecting the presence of voice-type traffic, reducing the bandwidth setting at the egress port of the network to manage non-voice type traffic, and monitoring the traffic to determine if the bandwidth setting needs to be adjusted. The apparatus includes a default maximum bandwidth setting and a mechanism for detecting and managing voice-type traffic in real-time. The technical effects of the patent include improved voice quality and efficient management of network bandwidth for voice traffic."

Problems solved by technology

However, QoS capabilities are limited in the downstream direction, which causes VoIP customers to experience poor voice quality when someone on their LAN (i.e., a home network) starts a large download.

Embodiment Construction

[0019]To achieve the desired objectives, the subject invention provides IP-based telecommunication services (i.e., VoIP) subscribers with the ability to dynamically control the bandwidth of data entering a LAN portion of a larger data network to improve voice communications therein. Real-time management and control are executed by an apparatus and method in an IP-based environment (i.e., the Internet). In a preferred embodiment of the invention, the voice traffic management functions operate as part of a larger VoIP telecommunication service. Such telecommunication service is, by way of example, part of any public or private data network (or combination thereof) constructed for (in part) and adapted to convert analog voice signals (e.g., generated by a human utterance) to a digitized and packetized format according to known and understood protocols (such as but not limited to Transmission Control Protocol / Internet Protocol (TCP / IP)) for transmission from an originating point (Party ...

Abstract

Method and apparatus for voice traffic management in a data network includes establishing a default maximum bandwidth setting at a LAN egress port when voice-type traffic is not present in a LAN portion of the data network, detecting voice-type traffic, reducing the bandwidth setting at the LAN egress port to effect a change in a rate of non voice type traffic and monitoring non voice type traffic and voice quality statistics to determine if the rate of non voice type traffic entering the data network has changed. Once the desired change has occurred, performing a linear increase of the bandwidth setting at the LAN egress port to a first value while monitoring voice quality statistics, determining if voice quality has degraded during increase of the bandwidth setting and repeating the last two steps if voice quality has not degraded.

Description

FIELD OF THE INVENTION [0001]The invention is related to the field of telecommunication devices and services and more specifically, the invention is directed to an apparatus and method that prioritizes and improves the flow of voice traffic in certain portions of a data network that also functions, in part, as a telecommunication system utilizing Voice over Internet Protocol (VoIP).BACKGROUND OF THE INVENTION[0002]VoIP is a technological development in the field of telecommunications that is utilized to transmit voice conversations over a data network using Internet Protocol (IP) packets rather than the existing and traditional telecommunications system more commonly referred to as the Public Switched Telephone Network (PSTN) or Plain Old Telephone Service (POTS). Entities (e.g., businesses or individuals) implement VoIP by purchasing and installing the necessary equipment (e.g., one or more Customer Premise Equipment (CPE) devices) to access a VoIP service provider and activating t...
