摘要： A packet relay device which realizes a QoS service with higher quality by improving an intra-device policy concerning packet discard. An input-side policing unit measures a first data rate of packets before being switched, and discards at least one of the packets before being switched, when the first data rate exceeds a first bandwidth value which is preset. A switching unit performs switching of the packets on which the input processing is performed. An output-side policing unit receives packets flowing together after being switched, measures a second data rate of a portion of the received packets corresponding to each value of a parameter, compares the second data rate with a second bandwidth value which is preset to be guaranteed for the value of the parameter, and discards at least one packet in the portion of the received packets when the second data rate exceeds the second bandwidth value.

摘要： An output-band control unit extracts delay information indicating a delay state of a packet from a packet received, and controls a setting of an output band of the packet based on the delay information. A packet-transmission control unit updates the delay information based on the output band of which the setting is controlled by the output-band control unit and an internal delay that occurs internally with respect to a packet output in the output band, and transmits the packet with the delay information updated.
摘要翻译：输出频带控制单元从接收到的分组中提取表示分组的延迟状态的延迟信息，并根据延迟信息来控制分组的输出频带的设定。分组传输控制单元基于由输出频带控制单元控制设置的输出频带和相对于输出频带中输出的分组内部发生的内部延迟来更新延迟信息，并且发送分组延迟信息更新。
