Summary:PROBLEM TO BE SOLVED: To provide an IP data processor which routes data processing by each protocol classification of an IP packet regarding the IP data processor. SOLUTION: The data processor which is connected to a network interface device includes: a bus control means between an external bus and an internal bus; and a data transfer processing means for performing data transfer with each part inside, wherein the data transfer processing means includes: a context information control means for managing context information of packet data to be exchanged with the network interface device; a protocol classification ID recognition means for recognizing a plurality of protocol classifications as protocol classification IDs; and a routing table which stores routing information by each protocol classification ID of the packet data, and determines the corresponding protocol classification based on the protocol classifications and the routing table, or which of a transfer paths of the internal bus and an interface means the data is transferred by each service.
