In today's distributed enterprise, applications such as Microsoft® SharePoint and Windows® File Share transmit an increasing number of files and data sets over Wide Area Networks (WANs), overburdening available WAN bandwidth. To make matters worse, these 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 solution.
The SonicWALL® WAN Acceleration Appliance (WXA) Series reduces application latency and conserves bandwidth, significantly enhancing WAN application performance and improving the end 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. Deployed in conjunction with a SonicWALL E-Class Network Security Appliance (NSA), NSA or TZ Unified Threat Management (NGFW) 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 SonicWALL NGFW Firewall, the WXA Series remembers data that has been transferred previously, and through data-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 SonicWALL WXA Series provides acceleration features such as data caching, metadata caching, data-in-flight compression and application traffic prioritization using QoS or bandwidth management on the managing NGFW Firewall.
Unlike standalone WAN acceleration products, SonicWALL WXA solutions are integrated add-ons to SonicWALL NGFW 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 remote, branch and central office deployments, the WXA Series is comprised of software and hardware based solutions including the SonicWALL WXA 500 Live CD, WXA 2000 and WXA 4000 hardware appliances, and WXA 5000 Virtual Appliance.
