WAN optimization is a technology designed to improve the performance and efficiency of Wide Area Networks (WANs), which connect geographically dispersed locations over the internet or dedicated lines. It works by reducing the volume of data transmitted over the network, thereby minimizing latency and bandwidth consumption.

WAN optimization techniques typically involve caching frequently accessed data at edge locations, thereby reducing the need for centralized data retrieval. It may also involve protocol compression and caching WAN data for subsequent access.

WAN optimization solutions often employ techniques such as WAN acceleration, caching, and protocol optimization. WAN acceleration involves compressing data before transmission, while caching stores frequently accessed data at edge locations to reduce the need for centralized data retrieval. Protocol optimization minimizes network traffic and reduces overhead.

The key benefits of WAN optimization include reduced bandwidth consumption, lower latency, and improved application performance. By minimizing network traffic and reducing latency, WAN optimization helps remote users access critical applications more efficiently, improving overall productivity.

WAN optimization is commonly used in enterprise environments, where traditional networks are often hampered by geographical distance and available bandwidth. It is also used in cloud and software-as-a-service (SaaS) deployments, which often require high-speed data transfer across geographically-dispersed locations.

Several WAN optimization technologies are available, including hardware and software solutions from various vendors. Some popular solutions include Riverbed's SteelConnect, Cisco's WAAS, and Silver Peak's Unity EdgeConnect. WAN optimization is often used in conjunction with other network technologies, such as Quality of Service (QoS) and traffic shaping.
