    • A multi-protocol switch that supports both ATM and IP traffic and method for use is presented. The multi-protocol switch associates certain input connections, as identified by virtual path identifier/virtual connection identifier (VPI/VCI), with either IP or ATM traffic. When the connection identifier for a cell received indicates that the cell is an ATM cell, the multi-protocol switch forwards the cell through the switch, where the forwarding is based on the connection identifier for the cell. If the connection identifier for a cell indicates that the cell is IP traffic, the cell is stored with other cells included in the IP packet to which the cells correspond within the ingress line card of the switch. The destination address included in the packet is used to determine a forwarding decision for the cells included in the packet. After at least partial reassembly, the packet is segmented and forwarded through the switch based on the forwarding decision determined from the destination address.
    • 提出了支持ATM和IP流量的多协议交换机和使用方法。 多协议交换机将由虚拟路径标识符/虚拟连接标识符(VPI / VCI)标识的某些输入连接与IP或ATM流量相关联。 当接收到的小区的连接标识符指示该小区是ATM信元时,多协议交换机通过交换机转发该小区,其中转发基于该小区的连接标识符。 如果小区的连接标识符表示该小区是IP业务,则该小区与包括在小区对应的IP分组中的其他小区一起存储在交换机的入口线路卡内。 分组中包含的目的地址用于确定分组中包含的小区的转发决定。 在至少部分重新组装之后,基于从目的地址确定的转发决定,分组并通过交换机转发分组。
