The Different Types of SD-WAN Architecture and Its Functions

SD-WAN architecture is a kind of virtual architecture that is acting as the foundation of networking to manage more easily than traditional WANs. Mostly this virtual can be used over the physical infrastructure. This sd-wan architecture brings the process layer to the cloud-based system.  All these processes are simple and also centralized too. This virtual network overlay on the physical one enables the network more elastic in nature and is flexible too. Every organization needed this architecture and let us see some of the reasons why this is much needed for the business and organization briefly.

All companies are moving to the cloud system hence they are investing more amounts in the flexible cloud system to improvise their networking. This architecture is providing the benefits and also the efforts that exactly the data centers deliver. This is a very simple process and can be used to connect any location unlike the traditional one. Because the traditional one is a complex process and also the cost involved in the implementation process is very high. Because the routers and other instruments used in this cost more.

This architecture offers the best practices and also reduced the recurring cost. The network system has wide control and also being simplified processes with convenient centralized network management.  The sd-wan architecture won’t demand any kind of extra procedures and also any special mechanism to communicate in the network to any endpoint.

There are different types of architecture are existed and let us see some of those here. These different types can get from the various vendors those offers the services. Those can be named as premises-based, internet-based, and also MPLS based.

Premises Based: This is one of the cost-effective processes in this sd wan networking. This is more suitable for smaller as well as localized businesses. In this type, functionality can be achieved by placing all the appliances onsite.

Internet Based: In this type the sd wan solutions may use the different appliances at the specified locations. For this, it will be used the public internet connections. Since the internet is used from the customer’s premises and those will be paid accordingly for the SD-WAN.

MPLS Based: This type of sd wan solution may generate the virtual internet protocol network. Usually, this may be between the appliances and also the vendors. This is a kind of hybrid network solution where the MPLS and SD-WAN are connected together. In this, the multiple appliances could be connected at the network endpoint.
