What is SD-WAN?

The Software-Defined Wide Area Network (SD-WAN) simplifies the wide-area network’s management, operations and resilience.

From communication providers to enterprises, SD-WAN aggregates transport services, MPLS, LTE, broadband internet services, i.e. virtually any type of WAN link. SD-WAN facilitates a secure connection among the application users.

How Does SD-WAN Work?

Using a centralized interface, SD-WAN ensures security and reliable connection across the WAN, typically the last-mile.

It offers application-aware and user-aware routing throughout the WAN, allowing applications to receive QoS and security policy enforcement accordingly. With SD-WAN, users can experience improved application performance.

It provides multiple security layers while maintaining excellent cloud performance on the local internet breakout of IaaS and SaaS application traffic. Ultimately, improving the user experience contributes to increasing productivity, scalability, eliminates challenges for IT.

SD-WAN vs MPLS

Essentially, the differences between SD-WAN and MPLS revolves around virtualization. SD-WAN virtualizes network functions on the network infrastructure allowing those functions to run as software on any commodity hardware whereas MPLS requires proprietary hardware.

This key difference in the way SD-WAN virtualizes network functions results in a less expensive, higher performance solution that also provides a higher level of security. MPLS comes with extremely high bandwidth costs which is simply not an issue for SD-WAN.

These crucial benefits are why IT infrastructure across industries continues to switch away from MPLS to SD-WAN.

SD-WAN Architecture

SD-WAN’s abstracted architecture, is arranged into two parts: the control plane and forwarding plane. SD-WAN architecture places the control plane in a centralized location to help teams manage it remotely. In this way, you can control the SD-WAN architecture without requiring the assistance of the IT team.

The Three Primary SD-WAN Components

  • SD-WAN Edge

    The endpoints of the network are on the SD-WAN Edge. These endpoints can either be a branch office, remote data center, or a cloud platform.

  • SD-WAN Orchestrator

    As the virtualized manager for the network, SD-WAN Orchestrator coordinates traffic and applies the policy and protocols. The operators execute these security protocols.

  • SD-WAN Controller

    SD-WAN Controller is the center for network management. This controller allows you to oversee the network in its entirety to be able to generate policies.

The Three Types of SD-WAN Architectures

  • On-Premises SD-WAN

    On-Premises SD-WAN is where the SD-WAN hardware can be found on-site. This hardware allows the network operators to manage the network without having to utilize the cloud directly. This direct access is ideal for handling confidential information that cannot risk getting sent over the internet.

  • Cloud-enabled SD-WAN

    From its name, cloud-enabled SD-WAN requires a connection to the internet to manage a virtual cloud gateway. This cloud makes the network more accessible to others with its improved integration and performance towards cloud-native applications.

  • Cloud-enabled + Backbone SD-WAN

    Cloud-enabled + backbone SD-WAN provides an additional back-up to the architecture, which allows the on-site architecture to connect to the SD-WAN provider’s closest point-of-presence (POP). It facilitates efficient traffic switching from the public internet to a private connection without a hassle. You can always ensure low levels of latency, packet loss, and consistency if the connection becomes overwhelmed.

Adapting SD-WAN Improves Services

Transitioning into SD-WAN orchestrated model means they have to leave the manual interventions behind, which opened doors for less taxing tasks. SD-WAN managed service providers tend to perform the design, deployment, and operation of WAN solutions for you.

Due to the drastic growth of SD-WAN, CSPs have no choice but to integrate their technologies for their managed services. It helps them maintain their relevance in the market providing scalable, flexible, and affordable services based on the customers’ needs.

Streamline Hybrid WAN

The primary service offered by most CSPs is the hybrid WAN. It lets MPLS consumers increase their managed internet bandwidth to the branch network. In turn, the internet circuits work minor traffic flows to the data center. It also handles the increasing amount of direct to cloud traffic. When CSPs implement SD-WAN to their infrastructure, they can provide managed, secured hybrid WAN services.

Through Gen 2 SD-WAN, you can showcase the infrastructure’s reliability, security, and traffic handling benefits to their customers.

Customer Service Providers that integrate SD-WAN can further help reduce the risks of inconsistent network and cyber threats. Many customers can begin embracing SD-WAN with the CSPs’ constant professional and support services.

Leveraging SD-WAN allows CSPs to deliver innovative and productive services across their clients and customers. This leverage enables CSPs to avoid the potential for disintermediation to their managed service business. It can likely happen from the inevitable increased use of Internet circuits for business traffic.
