Abstract:
1. Method of voice traffic management in a data network, the data network functioning, in part, as a telecommunication system based on Voice over Internet Protocol (VoIP) and having a wide area network (WAN) portion and a local area network (LAN) portion, the method comprising the steps of: (a) establishing a default overall maximum bandwidth setting for all data traffic at a LAN egress port of a device that provides WAN access to LAN network components when voice-type traffic is not present in the LAN portion of the data network; (b) detecting voice-type traffic in the LAN portion of the data network; (c) reducing overall maximum bandwidth setting for all data traffic at the LAN egress port to effect a change in a rate of non voice type traffic entering the LAN portion of the data network; (d) monitoring non voice type traffic and voice quality statistics to determine if the rate of non voice type traffic entering the LAN portion of the data network has changed; (e) performing a linear increase of the overall maximum bandwidth setting at the LAN egress port to a first value while monitoring voice quality statistics; (f) determining if voice quality has degraded during increase of the overall maximum bandwidth setting; and (g) repeating steps (e) and (f) if voice quality has not degraded.
