NETWORK DEVICE CONTROLLER, NETWORK SYSTEM, NETWORK DEVICE CONTROL METHOD AND STORAGE MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a network device controller, a network system, a network device control method and a storage medium where high-speed data communication is conducted by selecting a connection type data transmission method or a connectionless type transmission method depending on a size of transmitted data so as to use a datagram type packet and a data stream type packet. SOLUTION: A network management device 200 is provided with a CPU 201 that executes a network management program controlling transmission employing a connectionless type connection when a size of transmitted data is small and controlling transmission employing a connection type connection when a size of transmitted data is large.
