Abstract
A transmission system includes a calculation unit that calculates a jitter pattern sequence of a plurality of packets transmitted by a transmission device via a network using a transmission interval of the plurality of packets and a difference between arrival times at which the packets arrive at a reception device, a generation unit that inputs the jitter pattern sequence to a first learning model to generate a state index indicating a state of the network, and a buffer estimation unit that determines a buffer size of a reception buffer of the reception device based on the state index.
Claims13
A transmission system comprising:
- a calculation unit, including one or more processors, configured to calculate a jitter pattern sequence of a plurality of packets transmitted by a transmission device via a network using a transmission interval of the plurality of packets and a difference between arrival times at which the packets arrive at a reception device;
- a generation unit, including one or more processors, configured to input the jitter pattern sequence to a first learning model to generate a state index indicating a state of the network;
- and
- a buffer estimation unit, including one or more processors, configured to input the state index to a second learning model to determine a buffer size of a reception buffer of the reception device based on the state index.
A transmission method performed by a transmission system, the method comprising:
- calculating a jitter pattern sequence of a plurality of packets transmitted by a transmission device via a network using a transmission interval of the plurality of packets and a difference between arrival times at which the packets arrive at a reception device,
- inputting the jitter pattern sequence to a first learning model to generate a state index indicating a state of the network, and
- acquiring an observation value output from a reception buffer, and determining a buffer size of the reception buffer of the reception device based on the state index by using a deviation between the observation value or an estimation value estimated from the observation value and the state index.
A non-transitory computer-readable storage medium storing a transmission program for causing a computer to perform operations comprising:
- calculating a jitter pattern sequence of a plurality of packets transmitted by a transmission device via a network using a transmission interval of the plurality of packets and a difference between arrival times at which the packets arrive at a reception device,
- inputting the jitter pattern sequence to a first learning model to generate a state index indicating a state of the network, wherein the first learning model is a neural network generated by performing unsupervised learning using a slack time zone of the network as learning data, or by performing unsupervised learning in which labels are attached to the transmission interval collected from the transmission device and the arrival time collected from the reception device, and
- determining a buffer size of a reception buffer of the reception device based on the state index.
