To date the industry appears to have accepted a scenario of Ethernet in the LAN and ATM in the WAN as the underpinning of networking in the future. The billions of dollars spent by vendors on ATM technology and products make it is difficult to imagine ATM not becoming one of the two leading networking technologies. However, this enormous level of investment does not guarantee ATM's success.
