Three Type Of SD-WAN In Network Architecture

SD-WAN architecture is the high-level structure of the software and hardware system that make up the SD-WAN and how it’s deployed. The method of deployment or architecture is often determined by business scale, needs, and associated cost. In the SD-WAN architecture, the high-level structure of the software and hardware system that makes up the SD-Wan and how it’s deployed, the primary benefit or advantage is added security and organizations utilizing SD-WAN benefit from end-to-end encryption across the entire network. All devices and endpoints are completely authenticated, thanks to a scalable key-exchange functionality and software-defined security. All communication between a central data center and branch offices, as well as communication to and from the cloud, is secure.

SD-WAN is typically offered in three types in Network Architecture:

  • On-premise only/on-prem-only based SD-WAN solutions

It is condition that the SD-WAN architecture needs to deploy inside the premise in the organization. So organization need  SD-WAN box (essentially a plug ‘n play router), performing real-time traffic shaping at each site. Unlike some of the other architectures, the on-site SD-WAN box does not connect to a cloud gateway (discussed later). It only connects to your company’s other sites. So by applying this type of network architecture, it can lower or zero monthly SD-WAN cloud-enablement bandwidth costs, Multi-circuit/ISP load-balancing, Real-Time traffic shaping, improving the performance of all WAN apps and improved disaster recovery (DR), by having better connectivity backup.

  • MPLS-based SD-WAN solutions

MPLS-based SD-WAN solutions involve multiple appliances placed at network endpoints. These solutions create a virtual IP network between the vendor-proprietary appliances, giving them control of network packets from end to end.

  • Internet-based SD-WAN solutions

Internet-based SD-WAN solutions also use multiple appliances at each customer location, using public Internet connections from customer-chosen providers. The customer pays for a portion of its Internet connections to be SD-WAN.

Each of these architecture types varies in cost and benefits and might be more or less appropriate for a given environment. Regardless of the type, all of these solutions offer a full range of SD-WAN capabilities.

Please feel free to contact E-SPIN for your inquiry and requirement, so we can assist you on the exact requirement in the packaged solutions that you may require for your operation or project needs.
