摘要： In a bandwidth management apparatus that outputs packets by observing the bandwidth set value predetermined for each destination, provisions are made to prevent a situation where the contracted bandwidth cannot be provided due to influences from packets destined for other destinations. When performing bandwidth management using token buckets provided one for each destination, each token bucket is updated by setting the upper limit token value higher when any packet is stored in the corresponding queue than when no packets are stored; this serves to prevent a situation where even when a packet has already arrived at the queue, the packet cannot be output because a packet is being output from some other queue and, as a result, unconsumed tokens are discarded at the next update time.
摘要翻译：在通过观察对于每个目的地预定的带宽设定值来输出分组的带宽管理装置中，进行规定，以防止由于去往其他目的地的分组的影响而导致不能提供合同带宽的情况。当使用为每个目的地提供的令牌桶执行带宽管理时，当任何分组存储在对应的队列中时，通过将上限令牌值设置为高于不存储分组时更新每个令牌桶。这用于防止即使分组已经到达队列的情况，由于分组正在从其他队列输出，因此在下一个更新时间丢弃未消耗令牌的分组，因此不能输出分组。

摘要： In a packet transmission method and device, when a received packet is written in a packet buffer, an address of the packet buffer is stored as a read address for each destination corresponding to a physical port and storing information of the received packet. The read address of a destination designated by the received packet information is read and saved when the received packet is read out of the packet buffer in accordance with a scheduling control. Then, the saved read address is taken out in accordance with an arbitration control and a received packet corresponding to the saved read address is read from the packet buffer.
摘要翻译：在分组发送方法和装置中，当接收到的分组被写入分组缓冲器时，分组缓冲器的地址被存储为对应于物理端口的每个目的地的读取地址并存储接收的分组的信息。当根据调度控制从接收到的分组缓冲器中读出接收的分组时，读取并保存由接收的分组信息指定的目的地的读取地址。然后，根据仲裁控制取出保存的读地址，并从分组缓冲器中读取对应于保存的读地址的接收分组。

摘要： A data communication apparatus has a data retainer, a retain state manager, a guaranteed bandwidth manager, a surplus bandwidth manager managing outputting of output data having a destination retained in the data retainer to an output line on a per-destination basis when the output data is outputted to the output line with the use of a surplus bandwidth that is a surplus over a sum of guaranteed bandwidths, and a scheduler scheduling outputting of data retained in the data retainer to the output line, based on results of managements by the guaranteed bandwidth manager and the surplus bandwidth manager and a retain state managed by the retain state manager. The apparatus manages the bandwidth with improved accuracy at the time of communication using a surplus bandwidth.
