Abstract: |
The invention is a packet preprocessing circuit module in the circuit interface card used for high speed network distributing device, and its characteristic: it contains packet input circuit, packet output circuit connected with the packet input circuit through information sending queue memory and packet buffer memory, flow corresponding port memory and flow life value memory interconnected with the packet input circuit, life value automatic ageing processing circuit connected with the flow life value memory, and CPU interface circuit interconnected with the life vale ageing processing circuit and the packet output circuit. It corresponds to IPv4 and IPv6 packets, and can assure data packets belonging to the same data flow transmitted through the same port and achieve load balance between two ports as far as possible and it can implement linear speed processing of 40-1500 binary data packet. |
