    • A multiplex system for multiplexing packets into ATM cells to be transmitted, which can implement effective use of channels corresponding to irregular traffic qualities in services with various types of quality conditions in an actual environment. In response to a connection establishment request (S402), current required bandwidths B1, . . . , Bm are changed to B′1, . . . , B′m by adding the new connection, which causes bandwidths X1, . . . , Xm which are assigned to the channels to be changed. When the desired bandwidth including the requested connection is less than an available bandwidth of the corresponding channel, an assigned bandwidth change processing (S406) is activated to assign new bandwidths in accordance with desired bandwidths. The bandwidth assignment change is carried out by changing ratios of extraction rates of packets from the buffers in the multiplex system.
    • 一种用于将分组复用到待发送的ATM信元的多路复用系统,其可以在实际环境中实现具有与各种类型的质量条件的服务中的不规则业务质量相对应的信道的有效使用。 响应于连接建立请求(S402),当前所需的带宽B1,。 。 。 ,Bm改为B'1,。 。 。 ,B'm通过添加新的连接,导致带宽X1。 。 。 ,分配给要更改的通道的Xm。 当包括所请求的连接的期望带宽小于相应信道的可用带宽时,分配的带宽改变处理(S406)被激活以根据期望的带宽分配新的带宽。 通过改变来自多路复用系统中的缓冲器的分组的提取速率的比率来执行带宽分配改变。
