Abstract:
1. A method for switching VOIP packets in a data network, said method comprising the steps of: receiving a first packet in a network switch; determining if the first packet is a VOIP packet; determining a dynamically negotiated VOIP port for a VOIP session from at least one of the first packet and a second packet received in the network switch, if the first packet is determined to be the VOIP packet; and classifying all subsequent VOIP packets corresponding to the dynamically negotiated VOIP port in accordance with predetermined parameters and associating a priority with the subsequent packets to avoid network congestion; wherein the step of classifying all subsequent VOIP packets further comprises, storing the dynamically negotiated VOIP port; filtering all packets coming through the network switch having the dynamically negotiated VOIP port associated therewith; classifying filtered packets in accordance with predefined filtering actions; and wherein the step of storing the dynamically negotiated VOIP port further comprises generating a filter corresponding to the dynamically negotiated VOIP port and storing the generated filter in a filter table associated with a fast filtering processor.
