The invention provides a routing computation unit and network node equipment. The routing computation method comprises a multi-core processor, and an input interface and an output interface respectively connected with the multi-core processor; the input interface is used for receiving protocol control data; the multi-core processor is used for performing computation processing on the protocol control data by operating multiple sets of preset heterogeneous protocol stack software so as to obtain multiple computation results, and determining the routing data according to multiple computation results; the output interface is used for outputting the routing data. The network node equipment comprises at least one above routing computation unit. Through the routing computation method provided bythe invention, the attack for the routing computation unit can be effectively defended, the defense way is reliable and practical, thereby improving the security of the network node equipment.
