A facility is provided in which an ATM switch may operate as a switch in the provision of connection oriented services and operates as a router in the provision of connectionless services. In the router mode, the ATM switch may determine "on the fly" a route which may be used to forward received data cells to an intended destination and then forwards each of the data cells in sequence over the determined route. In the switch mode, the ATM switch operates conventionally and forwards a received data cell over a previously defined switched virtual path. In certain cases, the ATM switch may operate as a router only.

[ We claim:] [1.] A method of operating an Asynchronous Transport Mode (ATM) switch comprising the steps ofresponsive to receiving a first data cell associated with connection oriented services, forwarding the cell to its intended destination via a switched virtual circuit previously established for the cell, andresponsive to receiving, over a channel associated with connectionless services, a second data cell containing a predetermined virtual channel identifier common to connectionless service, performing a router function to determine a route from the ATM switch to the intended destination of the second data cell and forwarding the second data cell over a portion of the determined route.
