Introduction to WAN Acceleration - SonicWALL WXA 2000 Series

Today I am going to talk about the WAN accelerator of SonicWall. The model we are going to discuss is SonicWALL WXA 2000 Series. 

In today’s distributed business, efficient operation of bandwidth, increased safety, and ease of organization and controlling are important factors when considering a WAN acceleration solution. Throughput can be shattered by collaboration applications such as Microsoft SharePoint and Windows File Sharing. At the same time, due to the reputation of Web 2.0 and social media, an exponential upturn in Internet traffic is already overloading WAN bandwidth. 
This incompetent utilization of available bandwidth results in greater latency, dropping employee productivity. Expenditure more on augmented bandwidth or enhanced services, or purchasing dissimilar point solutions, does not resolve the problem.

The SonicWALL solution rationalizes the assignment, positioning, configuration, routing, management and integration of the WXA with other components such as VPNs. 
Consolidating WAN acceleration with core NGFW technologies including intrusion prevention, anti-malware, and application intelligence, control and visualization at the gateway significantly increases security while lowering the total cost of ownership.

The SonicWALL WAN Acceleration Appliance (WXA) Series allows you to easily and firmly enhance WAN application performance at remote and branch offices, thus improving the end user capability that leads to augmented efficiency.

Unlike standalone WAN acceleration products that are deployed either after the firewall or between the firewall and WAN router, the SonicWALL WXA Series is a cohesive add-on to the SonicWALL Next-Generation Firewall (NGFW). 
The powerful combination of a SonicWALL NGFW and WXA enables you to more efficiently manage your bandwidth and simplify NGFW and WAN acceleration implementation and management without bargaining security. 
SonicWALL makes it easy for you to add one or more WXA solutions into your network by providing a variety of platform options including both hardware and implicit appliances as well as software.
The explanation enables wide-ranging scanning for incursions and malware before accelerating the traffic across the VPN or devoted WAN link, thus amplifying security and performance. The WXA optimizes performance and decreases latency by communicating only new or altered data transversely the network after initial file transfer, resulting in artificially compact traffic volumes. In addition, the dealing firewall enables you to identify and highlight application traffic while the WXA minimizes traffic between sites.

Features & Benefits:
  • Extremely simplify distribution, routing and incorporation of multiple WXA appliances through your network through complete provisioning and configuration by a SonicWALL NGFW.
  • Add a level of security by visualising all data for threats before distribution it to the WAN Acceleration Appliance using SonicWALL Reassembly-Free DPI technology.
  • Enhance network effectiveness to give users LAN-like application performance over your WAN by decreasing latency and chattiness presented due to inefficient protocols or application communication.
  • Spread the long-term assessment of your existing WAN links and enhance the user experience by dramatically reducing bandwidth consumption through byte and file caching.
  • Hierarchy to meet the desires of a growing user population through clustering, which enables several SonicWALL WXA solutions to be linked together at each location.
  • Decrease total cost of ownership (TCO) by increasing efficiency and overall utilization of your existing WAN bandwidth, thus avoiding costly WAN upgrades.
  • Rise functioning and reduce latency with data compression across the WAN.
  • Expand response time while decreasing the amount of data transferred when downloading or accessing files from a shared drive, using Windows File Sharing (WFS) acceleration.
  • Upturn browser response time while decreasing bandwidth using HTTP (Web) caching.
  • Get improved insight into performance gains from WAN acceleration with real-time visualization.
  • WAN acceleration client software allows traffic initiated from remote Windows PCs or laptops running NetExtender to be accelerated.
