A network of a new configuration is flexibly constructed while maintaining a stable operation in the network. A management device includes: a detection unit that detects addition of a function unit to a network including one or a plurality of on-vehicle function units; an acquisition unit that acquires function unit information of a new function unit that is the function unit the addition of which has been detected by the detection unit and function unit information of each on-vehicle function unit, each piece of function unit information including information regarding network configuration of a layer lower than an application layer; and a generation unit that, based on the pieces of function unit information acquired by the acquisition unit, generates configuration information of a new network that is the network further including the new function unit.

A network of a new configuration is flexibly constructed while maintaining a stable operation in the network. A management device includes: a detection unit that detects a new function unit as a function unit to be newly added to a network including one or a plurality of on-vehicle function units; a generation unit that acquires function unit information of the new function unit detected by the detection unit and function unit information of the on-vehicle function unit, and generates, based on the respective pieces of function unit information, configuration information of a new network that is the network in which the new function unit is further included; and an acquisition unit that acquires, from a database in a storage device, feasibility information indicating feasibility of the new network and corresponding to the configuration information generated by the generation unit.
