Web accelerator module in F5 BIG IP

F5-BIGP WAM (Web accelerator module) helps to increasing server capacity through compression offload and caching, improving web application performance by providing content caching an image optimization.

Let’s take a scenario to better understand why WAN module is required in enterprise environment with key objective being to improve end user experience –


An organization has deployed a website which contains many graphical elements with large images which is creating problem for the users those are accessing the website for home especially from their Mobile devices. There users get latency due to extra hops from their mobile devices to hotspot/ Wi-fi then service provider and then back many times.  To overcome from these type of issues, BGI-IP introduced Web Accelerator Module (WAM) which optimize and increase the website performance by reducing the content you are delivering, so that users’ faster access to the website.

WAM sits in between your client and web application servers .It is built on full proxy architecture, which means it has substantial control on the traffic which is passing through the F5-BIG and client in addition to F5-BIP IP and webservers. WAM cache content on F5-BIG forces caching on the client Browser with the intent of moving content closer to the user, reduce the size of images by lowering the resolution quality, stripping out the unnecessarily data compressing and converting file format to make them more efficient. This method is especially beneficially for the mobile devices having smaller display sizes and slower mobile connections.

BIG-IP WAM Features and Functionality

  • Overcome WAN latency
  • Improves Application response time
  • Maximize server capacity
  • Image optimization, BGI-IP reduce size of image by 20-40%.
  • Reduce image quality and compress image
  • Convert to more efficient format like TIFF to JPEG, JPEG to JPEG-X
  • Combined multiple files of same format
  • BIG-IP caching Cache the contents from the server.
  • Content inline and re-ordering
  • Dynamic compression
