1. A management device to be used in an in-vehicle network including a plurality of function units that are installed in a vehicle and that are connected to each other via a relay device, the management device comprising:
processing circuitry configured to:
acquire state information indicating a state of the vehicle; and
change allocation of transmission bands of a plurality of logical paths in a set of the function units in accordance with the state of the vehicle indicated by the state information, wherein
a first logical path among the plurality of logical paths is realized by a plurality of transmission paths including a first transmission path and a second transmission path each being a physical transmission path, and
a second logical path among the plurality of logical paths is realized by a plurality of transmission paths including the first transmission path and a third transmission path each being a physical transmission path, the third transmission path being different from each of the first transmission path and the second transmission path.
