What is WAN Acceleration?
The WAN Acceleration service allows network administrators to accelerate WAN traffic
between a central site and a branch site, using Transmission Control Protocol (TCP)
acceleration methods, Windows File Sharing (WFS) acceleration, and Web caching. The Dell
SonicWALL WXA series appliance is deployed in conjunction with a Dell SonicWALL NSA/TZ
series appliance. In this type of deployment, the NSA/TZ series appliance provides dynamic
security services, such as attack prevention, Virtual Private Network (VPN), routing, and Web
Content Filtering. The WAN Acceleration service can increase application performance.
