Patent ID: 6956867

Claim:
A method of changing a fragment size of data packets in a router where a data packet is divided into data packets having the fragment size, and the data packets are transmitted to a network along with audio packets, comprising the steps of: acquiring, in the router, a parameter indicative of whether proper audio quality is maintained through ongoing transmission of the audio packets; and dynamically changing the fragment size of the data packets in response to the acquired parameter, wherein the step of dynamically changing further includes the steps of: comparing a current value of the parameter to an average value of the parameter; increasing or decreasing the fragment size in relation to a default fragment size when a deviation of the current value of the parameter from the average value of the parameter exceeds a predetermined threshold for a first predetermined period of time; and resuming the default fragment size when the deviation of the current value of the parameter from the average value of the parameter falls below the predetermined threshold for a second predetermined period of time.
