    • In a network communication apparatus, transfer and discard processing is realized for each transfer frame having a priority, and a band limitation is carried out to prevent the congestion of a transfer destination apparatus. Specifically, a bucket is provided for every priority, and tokens of an amount determined based on the priority are supplemented. Moreover, before a bucket evaluation, one shared bucket is provided. All of the tokens existing in the bucket provided for every priority are transferred to the shared bucket for every constant period. The tokens overflowing beyond a capacity of the shared bucket are discarded. All of the frames are equally evaluated and transferred regardless of the priority of each of the frames, as far as the token exists in the shared bucket. When there is no token in the shared bucket, switching to the preferential band limitation is carried out and each priority bucket is evaluated. The bucket corresponding to the priority of the frame is checked and when the token exists, transfer processing of the frame is carried out. When there is no token, discard processing of the frame is carried out.
    • 在网络通信装置中,对具有优先权的每个传送帧实现传送和丢弃处理,并且执行频带限制以防止传送目的地装置的拥塞。 具体地说,为每个优先级提供桶,并且补充基于优先级确定的量的令牌。 此外,在桶评估之前,提供一个共享桶。 存储在桶中的每个优先级中的所有令牌将每隔一段时间转移到共享存储桶。 超出共享存储桶容量的令牌被丢弃。 无论每个帧的优先级如何,只要令牌存在于共享存储桶中,则所有帧都被同等评估和传输。 当共享桶中没有令牌时,执行切换到优先带限制,并评估每个优先级桶。 对应于帧的优先级的桶被检查,并且当令牌存在时,执行帧的传送处理。 当没有令牌时,执行帧的丢弃处理。
