    • 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.
    • 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。
