AB - <p style="text-align: justify;">A new delay estimation model using a round trip time as a weight of the asymmetry of each host pair is developed. It improves the estimation accuracy and is suitable
for complex wide area network architecture. For large-scale scenarios in practice, we
design a symmetric Gauss-Seidel alternating direction method of multipliers. It significantly reduces memory consumption and computational cost. Numerical experiments
demonstrate the accuracy and efficiency of the model and algorithm.</p>
