Abstract:
1. A packet transmission apparatus connected to a network where packets of specific type are transmitted in preference to packets other than the specific type of packets, comprising: a flow detection unit that judges whether each of inputted packets is the specific type of packet or not; a packet transmission unit that transmits the inputted packet; and a bandwidth controller configured to determine whether a bandwidth related to the inputted packet exceeds a limit based on a type of the inputted packet, to judge whether the inputted packet is to be conformed to a traffic or not, and to perform an action to the inputted packet based on whether the input packet is to be conformed or not, wherein when a bandwidth related to the inputted packet does not exceed a first limit and a type of the inputted packet is a specific type, the inputted packet is judged to be conformed to traffic, when a bandwidth related to the inputted packet exceeds the first limit and a type of the inputted packet is a specific type, the inputted packet is judged not to be conformed to traffic, when a bandwidth related to the inputted packet does not exceed a second limit and a type of the inputted packet is other than the specific type while a bandwidth for a packet of a specific type is within the first limit, the inputted packet is judged to be conformed to traffic, and when a bandwidth related to the inputted packet exceeds the second limit, the inputted packet is judged not to be conformed to traffic.
