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.
This software-driven approach delivers a much better QoEx
than possible with
router-centric WAN model. With the time of easy internet access, the economics
of networking are redefined in terms of broadband services and the use of
SD-WAN technology.
