Abstract
A method, system, computer program product, and apparatus for reducing wasted bandwidth due to supercasting multicast cells through a router switch fabric is presented. A multicast destination address is compared to each destination address in a label-to-destination address table (LTDT) to determine the wasted bandwidth due to incorporating any additional switch fabric ports designated by the new destination address with beyond the switch fabric ports designated for each LTDT entry. Also considered is the amount of traffic experienced by each LTDT entry and that expected for the new destination address.
