The Best Practices Of WAN Acceleration And Optimization

Business organizations all over the world are becoming increasingly dependent on IT Services delivered over Wide Area Network or WAN. It enhances communicability over a diverse enterprise network spread globally. Your WAN can work based on VPLS, MPLS, or IP-Sec VPN over the web. Regardless of what the WAN operates on, optimization of the network performance can offer you several benefits. Apart from enhanced performance, WAN optimization can regulate the growth of bandwidth expenses. The business companies that operate globally require WAN optimization more than others. WAN Acceleration Technology can prove to be indispensable to them. Now, WAN Acceleration systems utilize a variety of technologies. This topic will describe the most commonly used ones.

Caching: Consider that you are transferring a file over the WAN network from the main office. When you do that, the systems will cache a copy of the data. If someone requests the same data, the WOC intercepts the requirement and delivers it locally. The WOC will communicate and keep you in synchronization about the changes that occur in the file.  It is how wan acceleration and optimization helps business organizations.

Compression: Upon compression, the file shrinks and reduces in size. Naturally, wan acceleration works proficiently in transferring the data at high speeds. Large files can otherwise take a lot of time to move even over the swiftest networks.

Data reduction: It is a technique which looks at the locally cached files. It also uses references to bring about changes in a file for transmitting the changed bytes. It can sometimes reduce data traveling over WAN by more than seventy percent. It is a much more effective technique when combined with relatively static data or file transfers with alterations.

Latency reduction: CIFS and TCP are highly sensitive to latency because of their chatterbox-like nature. They require two-way communication as they transmit small chunks of data. Until the confirmation of the first transfer arrives, the next one won’t transmit. Delivering one file can require 100,000 back and forth communications. You can reduce it by contemplating a protocol and accelerating the connection with proprietary algorithms.

Service quality and bandwidth management: Both these matters can address WAN links which are over-subscribed. They perform QoS by inspecting packets and prioritizing them based on an application, destination, source IP, and protocol. For example, web browsing and email checking can receive low priority. After all, there are other critical applications, like transaction processing.

Packet coalescing: This technique is the last one on this list. It helps with packets having large headers by consolidating multiple packets into a one. This consolidated packet has only one header.

The results

The outcomes of WAN Acceleration are self-explanatory. With it, the performance of your WAN systems can increase up to ninety percent or more in some applications. However, there are a few things which don’t see any improvement whatsoever. You should never forget the fact that all the suppliers are different. Every optimizer will provide you with something different. You need the expertise of knowledgeable people to determine the best WAN Acceleration supplier. You should resort to an expert to manage your procurement process. They can also help in assuring that you made the right decisions or not while obtaining the best prices.
