WAN Optimization consists of two components, acceleration and optimization.
- Optimization – Reduces the amount of data that traverses the link by using compression and caching techniques. Provides traffic shaping on the link to allow different users and applications to get appropriate access.
- Acceleration – Gets the data to the user faster by reducing and overcoming the limitations of the underlying protocols. There is a natural synergy between acceleration and optimization. When the amount of data is reduced, it will also get there faster.
