Patent ID: 7123585

Claim:
A method comprising the steps of: (a) recording traffic volume of packet data for a plurality of priority levels; (b) calculating a weighted average bandwidth for each priority level in said plurality of priority levels; (c) determining whether to reject packet data having a first priority level in said plurality of priority levels, wherein said step (c) includes the steps of: (1) determining whether an amount of packet data exceeds a first threshold; and (2) determining whether more than one weighted average bandwidths calculated in said step (b) exceeds a first predetermined value, and (d) rejecting the packet data with said first priority level, if said step (c)(1) determines that said amount of packet data exceeds said first threshold and said step (c)(2) determines that more than one weighted average bandwidth calculated in said step (b) exceeds said first predetermined value, wherein said first priority level has a highest weighted average bandwidth calculated in said step (b).
