Abstract
With the emergence of Distributed Router, a novel multicast forwarding method called NSFA (Novel Storage and Forwarding Approach) is proposed as the original forwarding approach TSFA (Traditional Storage and Forwarding Approach) has been out of date. In NSFA a new forwarding table model is developed, and what determines the times that packets are switched in the Internal High Speed Switched Networks is the number of outgoing line cards instead of the number of outgoing interfaces. In NSFA, compared with the previous method, the total number of times that packets are switched is considerable lower, which is validated in experiment. Through comparing NSFA and TSFA, it can be found that the memory consumption of NSFA is considerably less than TSFA.
