WAN optimisation is the process of utilising applications and products designed to improve the speed and efficiency of data transfer across a wide-area network (WAN). A key objective is to ensure bandwidth is prioritized for mission critical applications rather than less important processes. The result is improved file transfer speeds and more responsive applications.
Devices implemented to improve WAN performance are called WAN optimization controllers (WOCs). WOC’s relieve congestion, speed up file transfers and make applications more responsive.
Effective WAN optimisation generally comprises of:
•Traffic Shaping: Enables prioritisation of bandwidth allocations
•Data Deduplication: Reduces the amount of data required to be sent over a WAN
•Compression: Reduces the size of data files transferred over a WAN
•Monitoring: Detects non-essential traffic
