A complete guide on SD WANnetwork management

It’s a software-defined wide area network, which creates a virtualized network overlay by abstracting a network from its hardware. A single unified SD-WAN can consolidate network connectivity and enable orchestration of application delivery over an entire network, while an enterprise SD-WAN can upgrade network and catapult business into the digital era.

What does SD-WAN stand for?

Software-defined wide area network SD-WAN is a term that refers to a network that is defined by software or networking. Sd wan network management is based on a simplified design.

The network is subdivided into two parts in an abstracted architecture

  • The control plane
  • Forwarding plane.


Physical routers are used in traditional WANs to connect remote or branch users to applications located in data centers. SD-WAN decouples control and administration from the underlying networking hardware, allowing them to be configured and deployed as software. Using a single control panel, network administrators can create new rules and policies, then configure and distribute them across an entire network.


SD-WANs are thought to have several characteristics.

  • Centralized control
  • Multi-connection, multi-transport
  • Dynamic path selection
  • Policy-based management
  • Service chaining

Key Takeaways

  1. SD-WAN is a virtualized wide-area network that separates the software from the hardware.
  2. Some of its key features include network abstraction, WAN virtualization, policy-driven centralized management, and elastic traffic control.
  3. Its architecture can be cloud-only, cloud-only with a backbone, or cloud-only with a backbone.
  4. Sd wan network management can run on off-the-shelf hardware rather than bespoke gear, lowering capex.
  5. It has several advantages, including easier management, improved network visibility, lower costs, and less vendor lock-in.
  6. MPLS came before it, and it’s still utilized in some cases where security is a problem.


The key benefits include:

  • Increased bandwidth for less money by supplying network traffic at optimal speeds and throttling low-priority applications.
  • Branch network management is centralized via a simple management panel, removing the need for manual configuration and on-site IT personnel.
  • Full network visibility is provided by the controller, which provides operators with a comprehensive view of the network.
  • Because the network can run on COTS hardware and use both private and public connections to route traffic, there are more options for connection type and vendor selection.

SD-WAN monitors WAN connection performance and manages traffic to maintain high speeds and optimize connectivity. Using a centralized control panel, network administrators can create new rules and policies, then configure and deploy them across an entire network.
