PROBLEM TO BE SOLVED: To provide a method allowing high-speed packet processing even if the high-layer packet processing is performed in a packet repeater, such as a router, a layer 2-3 switch. SOLUTION: In the packet repeater, such as the router, the layer 2-3 switch, the multilayer high-speed packet processing method is applied to a packet which is decided to perform relay by layer 2 and 3 routing and low-layer packet filtering by means of a conventional ASIC (Application-Specific Integrated Circuit). Additionally, packet repeating processing is performed by preparing a plurality of high-layer filtering functions by means of the ASIC or a network processor according to the analyzing contents of every layer or the packet.
