Packet transmission system, transmission device, transmission path switching method, and transmission path switching program

A transmission path switching method comprising:

• monitoring bandwidth information of a first radio section in a first transmission path and a second radio section in a second transmission path, each connected to an endpoint device, for each flow;
• determining a packet transmission path for transmitting a packet on the basis of the bandwidth information of the first radio section and the second radio section;
• calculating a bandwidth ratio of flows on the basis of the bandwidth information of the first radio section and the second radio section, and determining a bandwidth control value;
• and
• controlling a bandwidth of each flow on the basis of the bandwidth control value.

A non-transitory computer readable medium storing a transmission path switching program causing a computer to execute:

• processing of monitoring bandwidth information of a first radio section in a first transmission path and a second radio section in a second transmission path, each connected to an endpoint device, for each flow;
• processing of determining a packet transmission path for transmitting a packet on the basis of the bandwidth information of the first radio section and the second radio section;
• processing of calculating a bandwidth ratio of flows on the basis of the bandwidth information of the first radio section and the second radio section, and determining a bandwidth control value;
• and
• processing of controlling a bandwidth of each flow on the basis of the bandwidth control value.
