The invention belongs to the field of
network management and
traffic engineering, and discloses a routing optimization method based on traffic
matrix completion prediction, which comprises the following steps: step 1, constructing a routing matrix A and collecting a link
load vector at the current moment, and step 2, constructing a traffic
matrix completion model and outputting a complete traffic matrix. 3, constructing a space-time
traffic prediction model, and outputting a predicted traffic matrix at the next moment; 4, connecting the traffic
matrix completion model and the space-time
traffic prediction model in series, and defining a joint
loss function to perform parameter updating on the whole end-to-end network; and step 5, pre-evaluating a pre-estimated load state, dynamically adjusting a
link weight and generating an optimal routing strategy by utilizing the output predicted traffic matrix at the next moment and combining
network topology information, and finally issuing configuration to a
data level to realize routing optimization of traffic transmission. According to the method, the integrity of the traffic matrix is ensured, adaptive attention to the key link is realized, and the complemented data highly conforms to
future trend prediction.
