WAN Optimization is a significant part of programming business since it manages an assortment of the right methods that are answerable for expanding the effectiveness of information move across Wide Area Networks (WANs). It's what encourages us to move the most extreme measure of information across systems utilizing the base assets conceivable. It builds proficiency of framework by lessening the measure of information to be moved (utilizing methods like deduplication) and by beating inactivity. Proceeding onward further, the next piece of WAN enhancement is Software-Defined WAN Optimization. Wanos Networks is one such stage that gives its clients SD wan improvement with an expanded proficiency control, information security, and ROI (Return on Investment).

 Utilizing SD wan enhancement decreases or thoroughly dispenses with the need to utilize any sort of switches independently on the grounds that the essential control is unified. Control is isolated from the equipment which disentangles the board of systems and improves the conveyance procedure.

 SD wan advancement follows the standard of Dynamic way determination which implies that it is fit for choosing way for the traffic onto one or other WAN connection relying upon the traffic control stream as needs be all alone. Information may be expected to move to another connection on the off chance that it isn't working well indeed or so as to keep up the traffic stream balance.

 Highlights gave by Wanos Networks -

1. All-inclusive Deduplication:- It helps in decreasing repetition by dispensing with copy information at the byte level and utilizing references.

 2. Bundle Loss Recovery:- Due to interface quality, there's consistently parcel misfortune in information transmission. Wanos is arranged to give Packet Loss Recovery to expand TCP speeding up.

 3. Stream Compression:- Stream pressure of ongoing information helps in sparing data transfer capacity and expanding pressure proportions.

 4. Nature of administration:- Wanos Networks give the best Quality of Service there is by offering need to significant business traffic and lessening need of mass traffic.

 5. Layer7 Firewall:- Layer7 firewall is an Application layer firewall of Open System Interconnection gave to help application and end-client forms along these lines expanding information security.

It is a general misconception among many people that WAN optimization and WAN acceleration applies the same technology. They can both be termed as the “application acceleration”, but mistaking them for being synonyms is not the right approach. This confusion arises mainly because the ultimate goals of both the technology are somewhat similar. Some of them have been listed below:-

• Improved network and resource utilization

• Better end user experience; and

• Maximized network performance

The main difference between the two lies in their methodology and how they are being used by the operators to get the desired results.

WAN optimization mainly provides a generic blanket or to say a higher level of optimization. The main reason behind this feature is that it focuses on network and transport layer protocols through the means of SSL sessions. Many major companies opt for the DRE product line as it includes selective acknowledgments, larger window, and buffer sizes. Apart from more this it also provides assistance in improvement on slow starts and the congestions mechanism.

On the other hand, Application acceleration is more devoted to the lower layer of the OSI model, mainly the application layer and provide only certain improvements. Another important aspect of WAN acceleration is that it may not have been designed to be used outside of a LAN. It mainly removes the excess chatter from the file transfer protocol mainly CIFS. But certainly WAN acceleration has many hidden benefits that have been listed below:-

•    Provide LAN-like performance for mobile employees, anywhere

•    Grow without paying for additional bandwidth

•    Provide faster connectivity for branch offices

•    Speed data backups across the network

At last, it all depends on your need and requirement as to which application should be installed. Performance of both the technology speaks for themselves.

To improve the end user’s experience an appliance is added that optimizes the bandwidth. This appliance is usually termed as WAN accelerator.

The appliance can be attached in the form of a physical hardware component, software program or an appliance running in a virtualized environment. In simple terms, its job is to speed up the time taken for information to flow back and forth across the WAN. The major techniques applied by the WAN accelerator are compression and data deduplication to reduce the amount of data that needs to be transmitted. What an accelerator does is, it cache the duplicate files or parts of files so they can be referenced instead of being sent all over again through WAN.

Initially, accelerators required to set up a dedicated hardware appliance at each end of the WAN link to make things work smoothly. It was acceptable by large enterprise WANs that needed to connect the branch office to a centralized corporate data center. This was not feasible for the company’s mobile or remote users as it would take up most of the space and with all the wiring it created trouble. Taking all these parameters in mind WAN accelerator vendors introduced mobile software clients that act as localized appliances. This would allow the remote user’s computer to cache duplicate files and parts of files locally. These mobile clients can either connect to corporate WAN accelerator hardware appliances or to dedicated headquarters servers.
