The role of CISCO WAAS is to optimize the traffic among the central and remote stations for even faster processing, especially where you are dealing with Multimedia type data. Basically, CISCO WAAS brings in better response time and reduced bandwidth requirements when you are implementing a WAN that includes a central server connected to different remote workstations.
Cisco WAAS either comes as an appliance, software or hardware integrated module in Integrated Service Routers. WAAS appliances offer outstanding deployment scalability and design flexibility while WAAS software delivers best-in-class application acceleration for enterprise network.

CISCO WAAS – How does it Work?
There are three main components of CISCO WAAS: TFO, DRE, and Persistent LZ compression.
The CISCO WAAS Transport Flow Optimization (TFO): The TFO allows quick logins and logouts – to avoid congestion with many people logging in at the beginning of their shift. In addition, it also offers protection to the data packets travelling over the WAN and reproduces copies of lost packets quickly to avoid delay in WAN response time.
The CISCO WAAS Data Redundancy Elimination (DRE): This component of the CISCO WAAS keeps an eye on all the data packets traversing across the WAN and eliminates any duplicate packet to reduce the overload – again improving congestion and thereby increasing the response time.
Persistent LZ Compression: The role of this module is to keep the bandwidth requirements down to minimum for each user. It can compress data to 5:1, based on the type of application and data in use.
Overall, all these three components offer excellent optimization of any WAN. Though, most IT organizations employ only TFO to avoid traffic congestion, including the other two components offer even more optimization to the WAN performance.
