Abstract:
A method of relieving congestion in a packet-based network, said network comprising a plurality of nodes having data to be transferred there between, and utilizing a concept of virtual pipelines between gateway nodes of said network, said pipelines comprising one or more channels, said method comprising the steps of:(1) identifying a first set of virtual pipelines for which traffic exceeds a predetermined threshold; (2) for each virtual pipeline in said first set, determining a minimum pipeline size that would cause said traffic through said pipeline to not exceed said predetermined threshold; and (3) for each pipeline in said first set, selecting a voice compression algorithm to be applied to future calls using said pipeline, said voice compression algorithm having a compression ratio determined as a function of a ratio between a current size of said pipeline and said pipeline size that would cause said traffic through said pipeline to not exceed said predetermined threshold.
