1. A network management system comprising:
a plurality of edge apparatuses connected to a network; and
a network management apparatus connected to the plurality of edge apparatuses,
wherein
each of the plurality of edge apparatuses comprises a network interface, at least one processor, and a memory connected to the processor, the at least one processor configured to include
a shaping function configured to transfer a packet input from a user apparatus to the network using a token bucket algorithm,
a token supply amount control function configured to supply a token to the shaping function, and
a notification function configured to store the amount of tokens supplied by the token supply amount control function to the shaping function and notify the network management apparatus of data including a time point and an instantaneous throughput value calculated from the total amount of tokens in every set notification cycle, and
the network management apparatus comprises a network interface, at least one processor, and a memory connected to the processor, the at least one processor configured to include
an acquisition function configured to acquire the data from each of the plurality of edge apparatuses, and a management function configured to add up instantaneous throughput values of all the data at an identical time point and regard a sum of the instantaneous throughput values as an instantaneous traffic amount at the identical time point in the network.
