In today’s distributed enterprise, applications such as Microsoft SharePoint and Windows File Sharing transmit an increasing number of files and data sets over Wide Area Networks (WANs), overburdening available WAN bandwidth. To make matters worse, such collaboration applications can inefficiently retransmit entire files (rather than just incremental changes) multiple times, unnecessarily increasing WAN traffic. IT often responds by expending budget on more bandwidth or enhanced services. Alternatively, WAN acceleration technology can resolve the problem by allowing more efficient utilization of the existing network bandwidth.
The SonicWALL WAN Acceleration Appliance (WXA) Series reduces application latency and conserves bandwidth, significantly enhancing WAN application performance and user experience for small- to medium-sized 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. The WXA de-duplicates data traversing the WAN, thus reducing application latency and conserving bandwidth. Other acceleration features include data caching, metadata caching and data-in-flight compression.
Unlike standalone WAN acceleration products, WXA solutions are integrated add-ons to SonicWALL E-Class Network Security Appliance (NSA), NSA and TZ Series appliances that are deployed as Next-Generation Firewalls. This integrated solution streamlines the placement, deployment, configuration, routing, management and integration of WXA with other components, such as VPNs. When deployed in conjunction with SonicWALL Application Intelligence and Control Service, the WXA offers the unique combined benefit of both prioritizing application traffic (using QoS or bandwidth management) and minimizing traffic between sites, resulting in optimal network performance.
