Packet transmission method, packet transmission apparatus, and storage medium

摘要

A packet transmission method includes receiving a packet having a first service class; determining a maximum transfer band of the first service class, based on maximum transfer band information for each of a plurality of service classes of each of a plurality of computers; determining a transfer band of the first service class, based on traffic amount information for each of the plurality of service classes; transferring the received packet in the first service class, when the transfer band is smaller than the maximum transfer band of the first service class; determining whether a second service class includes a free band, based on the maximum transfer band information, when the transfer band of the first service class is not smaller than the maximum transfer band; and transferring the received packet in the second service class, when it is determined that the second service class includes the free band.

主权项

1. A packet transmission method using at least one of a plurality of service classes executed by a computer among a plurality of computers in a network, the transmission method comprising:
assigning, for each of the plurality of service classes, a value of a maximum transfer band indicating an upper limit of a traffic amount corresponding to the computer; receiving a packet transferred according to a first service class among the plurality of service classes; measuring a traffic amount related to the first service class; determining whether the received packet is encapsulated; transferring the received packet according to the first service class without encapsulating the received packet, when it is determined that the received packet is encapsulated and when the measured traffic amount is equal to or smaller than the value of the maximum transfer band corresponding to the first service class assigned by the assigning; determining whether a second service class which is different from the first service class and including a free band, exists among the plurality of service classes, based on the value of the maximum transfer band assigned for each of the plurality of service classes, when the measured traffic amount is more than the value of the maximum transfer band corresponding to the first service class; encapsulating the received packet using a header including information of the second service class, when it is determined that the second service class exists; and transferring the encapsulated received packet in the second service class.
