摘要： A network routing switch includes a crosspoint switch, a set of Ethernet I/O ports, a set of ATM I/O ports, a reassembly unit for converting ATM transmissions into Ethernet transmissions, and a segmentation unit for converting Ethernet transmissions into ATM transmissions. As an ATM I/O port receives cells of an ATM transmission from an external source it stores them until the transmission is complete and then sends the ATM transmission through the crosspoint switch either to a forwarding ATM port or to the reassembly unit depending on whether the ATM transmission is to be forwarded as an ATM or Ethernet transmission. When the reassembly unit receives an ATM transmission it converts it to an Ethernet transmission and forwards it through the crosspoint switch to a forwarding Ethernet I/O port. When an Ethernet I/O port receives an Ethernet packet from an external source, it sends the packet through the crosspoint switch either to a forwarding Ethernet port or to the segmentation unit, depending on whether the Ethernet packet is to be forwarded as an Ethernet or ATM transmission. When the segmentation unit receives an Ethernet packet it converts it to an ATM transmission and forwards it through the crosspoint switch to a forwarding ATM I/O port.
