    • An asynchronous transfer mode (ATM) network includes a plurality of data links interconnecting a plurality of data exchange nodes, and a plurality of data terminals connected by data links associated therewith to the data exchange nodes in the ATM network. In the ATM network, a virtual circuit is selectively established over which a series of data packets including one or a plurality of coded cells is routed from a source terminal toward a destination terminal. Each of these cells includes an information field and a header section. The terminals are assigned with identification parameters respectively, which parameters are uniform in value within the network. When a cell is transferred from the source terminal to the destination terminal along a presently determined route including selected links associated with certain data exchange node or nodes, a specific identification parameter being assigned to the destination terminal is written into the header section of the cell. This cell is then transferred toward the destination terminal on the basis of the specific identification parameter without causing this parameter to be written or converted at the certain data exchange node or nodes in the presently determined route.
    • 异步传输模式(ATM)网络包括将多个数据交换节点互连的多个数据链路和通过与其相关联的数据链路连接到ATM网络中的数据交换节点的多个数据终端。 在ATM网络中,选择性地建立虚拟电路,通过该虚拟电路将包括一个或多个编码单元的一系列数据分组从源终端路由到目的地终端。 这些单元中的每一个包括信息字段和标题部分。 终端分别具有识别参数,哪些参数在网络内的值是均匀的。 当小区沿着包括与特定数据交换节点或节点相关联的所选择的链路的当前确定的路由从源终端传送到目的地终端时,分配给目的地终端的特定标识参数被写入小区的报头部分。 然后,基于特定识别参数将该小区传送到目的地终端,而不使该参数在当前确定的路由中的特定数据交换节点或节点处被写入或转换。
