The Dell™ SonicWALL™ WAN Acceleration Appliance (WXA) Series reduces application latency and conserves bandwidth, significantly enhancing WAN application performance and improving the end user experience for distributed organizations with remote and branch offices. After initial data transfer, the WXA Series dramatically reduces all subsequent traffic by transmitting only new or changed data across the network. Deployed in conjunction with a Dell SonicWALL E-Class Network Security Appliance (NSA), NSA or TZ Next-Generation Firewall and Application Intelligence and Control Service, the WXA offers the unique combined benefit of prioritizing application traffic and minimizing it between sites, resulting in optimal network performance.
Conserving network bandwidth.
When integrated with a Dell SonicWALL Next-Generation Firewall, the WXA Series remembers data that has been transferred previously, and through data de-duplication, replaces repeated byte sequences with an identifier to reduce application latency and conserve bandwidth.
A variety of acceleration techniques.
In addition to data de-duplication, the Dell SonicWALL WXA Series provides acceleration features such as data caching, metadata caching, Web (HTTP) caching, data-in-flight compression and application traffic prioritization using QoS or bandwidth management on the managing Next-Generation Firewall.
Unlike standalone WAN acceleration products, Dell SonicWALL WXA solutions are integrated add-ons to Dell SonicWALL Next-Generation Firewalls. This integrated solution streamlines the placement, deployment, configuration, routing, management and integration of WXA with other components, such as VPNs.
To fit a wide variety of remote, branch and central office deployments, the WXA Series is comprised of software- and hardware-based solutions, including the Dell SonicWALL WXA 500 and WXA 6000 software, WXA 2000 and WXA 4000 hardware appliances, and WXA 5000 Virtual Appliance.
