Abstract
A method and system for logical multicasting on an Asynchronous Transfer Mode ("ATM") switch. There is a logical replication of cells on the same physical port of the ATM switch. A block of consecutive CIs is used by the controller in the switch to create new cells. The CIs are used to control the flow through the switch and for updating the VPI and VCI. These routing tags are part of the header information and multicast to the same physical port
