WAN optimization is a phrase used to describe applications and products used to manage and accelerate the flow of data across a wide-area network (WAN). Some specific technologies used in WAN optimization include the following:
Numerical Nonlinear Global Optimization. Numerical algorithms for constrained nonlinear optimization can be broadly categorized into gradient-based methods and direct search methods. Gradient-based methods use first derivatives (gradients) or second derivatives (Hessians). Examples are the sequential quadratic programming (SQP) method, the augmented Lagrangian method, and the (nonlinear) interior point method. Direct search methods do not use derivative information. Examples are NelderâMead, genetic algorithm and differential evolution, and simulated annealing.
