OverWatch: A Cross-Plane DDoS Attack Defense Framework with Collaborative Intelligence in SDN

Algorithm 2

DDoS attack classifier training process.

Require: Weight matrix of the hidden layer:

Bias vector of the hidden layer:

Ensure: Training dataset

for all number of training iterations do

Train the single layer autoencoder using back-

propagation:

Sample minibatch of //get batches

of traffic records

Update by using gradient descent method to
