Abstract (en)

[origin: WO0057606A1] A method for discarding data within an IP-network communications link (10) in a manner that optimizes the quality of speech data contained in the IP-network communications link (10). Initially, the IP-network communications link (10) is monitored to determine the occurrence of an overload condition. At least a portion of a plurality of data packets (30) within the IP-network communications link (10) are selected in response to detection of the overload condition. The selected portions are discarded from the IP-network communications link (10), and the remainder of the packets (30) transmitted on the link (10).
