Abstract
A packet forwarding system to transfer packets through a plurality of interfaces by reading out information for the packet forwarding beforehand includes a packet processor that organizes and processes data to be transferred into packets, a packet memory storing the organized packets, a plurality of interfaces respectively transferring the packets stored in the packet memory depending on destinations of the packets, and a packet forwarding manager managing an packet information to transfer the packets through the plurality of the interfaces, respectively, and to control transfer of the packets immediately through a corresponding interface of the plurality of the interfaces by reading out the packet information before the packet forwarding. Accordingly, the fast packet forwarding is realized by processing the packet information read and the actual packet forwarding in parallel.
