#wifi optimizer

To get better leverage of transport services many enterprises structured the WAN architecture with a software-defined Wide area Network. To securely connect users with the application they mainly included MPLS, LTE and broadband internet services.

The main subject of installations of WAN optimizer is to securely and intelligently direct traffic across the WAN network areas. It certainly increases the performance of the application which ultimately boosts the user experience.

WAN initially did not function as a cloud-friendly network rather it operated as conventional routers. These handlers also required to install backhauling functionality to divert traffic. This worked somewhat on the same parameters as a cloud – and operated as a hub or headquarters. It also meant that the headquarters required advanced security inspection for better functionality.

The major problem with WAN optimization was that it took a lot of time to transfer the data which ultimately delayed the whole processing. The traditional WAN was than supported with additional support from the application as SD-WAN optimizer.

Wan was set to select the traffic based on a few parameters like a priority, quality of services and other security needs as per business. This conventional router functioned all across the network and these simply route the traffic based on TCP/IP address and ACLs.

This application could identify the applications that are driven via traffic across WAN network simply using the TCP/IP addresses. It certainly simplified the technology for the user and they started to get the hang of it. The main Headquarters were the base was set up as a peer-to-peer connection set forth the untrusted, unknown or suspicious traffic.

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.
