  • Resource allocation calculation apparatus and resource allocation calculation method to enhance fairness and efficiency in allocation of resources among multiple virtual networks within a physical network
    Patent number: 11665109
    Abstract: A resource allocation calculation device includes: a demand prediction unit that for each of a plurality of virtual networks sharing a physical network, predicts demands in units of communications sharing common origin and destination nodes; and an allocation calculation unit that based on the demands predicted by the demand prediction unit, observed past demands in the units of communications and past allocated bandwidths in the units of communications, calculates allocated bandwidths and allocated routes at a current time for the respective units of communications in such a manner that fairness between utilities of the respective virtual networks is maximized, which enhances fairness and efficiency of allocation of resources to a plurality of virtual networks sharing resources of a physical network.
