Many times when administrators face network bandwidth constraints in distributed networks, the first solution that comes to mind is to increase bandwidth speed. However, even after increasing speed, administrators sometimes find that applications are still running slower than expected. The solution? Implementing WAN optimization.

Let's take a look at one example of how to take advantage of WAN optimization. Assume an administrator is responsible for managing a remote site. He decides to deploy a WAN optimizer at both of the end points between the server and router, one at the main data center, and one at another remote site. He knows that there are different ways WAN optimization can be used, but he also knows that the most important method is caching. One day the administrator needs to transfer a file from his primary data center to the branch office. In this situation, the optimizer caches the file sent for the first time and then sends the cached data on the second request. As a result, the speed of the information sent to applications or users at the remote site is greatly increased.

There are also various other ways WAN optimization can be used to enhance network performance. Some of these methods include application acceleration, TCP optimization, data compression, etc.

Here's a list of WAN optimization benefits:

#1 Access your files faster – If someone wants to share files frequently, caching can allow faster file access by storing the data transferred earlier. When caching occurs, only new data is saved. This helps you avoid excess network bandwidth utilization and increases performance.

#2 Increase your application’s performance – Once implemented, WAN optimization allows users to immediately feel the effect on their application’s performance. This is because bandwidth used for other data transfer can now be utilized by applications.

#3 Make your remote backup process easier – With WAN optimization, administrators can have a more reliable data recovery process. It allows them to reduce ‘time to respond’, resolve application downtime issues faster, and help users reclaim access to business critical applications with ease.

#4 Increase your network’s efficiency – With reduced latency through WAN optimization, administrators can solve network bottlenecks and optimize bandwidth utilization.

#5 Increase data transfer speed – By allowing users to quickly access data in remote offices, administrators can eliminate network issues caused by latency. WAN optimization also helps in faster data transfer between branch offices in different time zones.

#6 Reduce costs on network bandwidth – With methods like caching, application acceleration, and compression, you can use WAN optimization to reduce expenditures on network devices, bandwidth usage, and third party software.

With all these benefits, you can rely on WAN optimization without affecting your current network setup and stop worrying about network performance.
