What is SDN Network Management?


The COVID-19 pandemic has touched most aspects of personal and business life. The corporate world has seen changes in markets, customer behavior, and the economy.

We’ve seen institutions and facilities closing for indefinite time periods. Sporting, art, graduation, and other events were postponed. Due to quarantines and social distancing, businesses sent employees home to work remotely.

All these changes impact business planning. As the collected data changes, companies must adapt to meet new market targets. New Software-Defined Networking (SDN) infrastructures are helping analyze the data.

Are you wondering, “What is SDN?”. Keep reading this overview of SDNs and to find the benefits for your company.

What Is SDN Network Mangement?

An SDN describes a newer architecture that controls and separates data. It’s adaptable and dynamic to handle high-bandwidth applications.

The SDN architecture decouples the network control. Thus, it allows two or more systems to interface without a direct connection. These systems, components, or elements may have little to no knowledge of each other.

This network forwards functions that allow the SDN to control the underlying infrastructure. It completes direct programming to create an abstraction for applications and network services.

SDNs have a conceptual or physical controller that “views” the entire network. This centralized controller makes decisions for the network. One of its key tasks is to route the data flow and optimize performance.

Why Is SDN Important to Businesses Today?

In 2021, organizations must change their priorities regarding applications. Now the need focuses on supporting employees, operations, and competitiveness. Every key operating decision relies on the data collected by their network.

Businesses now seek network vendors who can enhance their access to data analysis. Bolstering network security has also become a prime directive as cyberattacks rise. This means businesses need solutions that protect data during distribution to other environments.

Organizations and their networks must maintain a flexible and agile posture. This allows them to stay on the leading edge of the rapidly changing market.

In 2020, companies learned that their biggest needs were work-from-anywhere (WFA) tools. Their productivity relied on workers being able to establish remote network connections. This meant that companies had to rework their infrastructure and security protocols.

Software-defined Wide Area Network (SD-WAN) and Secure access service edge (SASE) helped achieve WFA. The SASE architecture combines SD-WAN into a secure cloud service. This approach facilitated WAN deployment, security, and efficiency at an appropriate bandwidth.

Since this solution is scalable, it allowed for billing based on usage. It gave companies a great tool in a time of rapid change. Even as workers return to the office in 2021, experts predict businesses will still use SDNs.

Advantages of an SDN Network

SDNs promote faster and better decision-making about network performance. Companies can see how to utilizes the data for the best outcome. These networks give employees access to the resources, tools, and insights they need.

There are many benefits for companies using SDNs. These advantages include:

Direct programmability

Remember that SDNs are decoupled from the forwarding functions. This means you have direct programming network controls to meet your unique needs.

Agile Network

SDN architectures increase control via the virtualization of software. This network offers easy configuration and management.

Thus, IT administrators can dynamically change network-wide traffic flow as needed. It also allows easy integration with your current technologies.

Central Control

The SDN’s controllers “logically” centralize the network intelligence. This gives it a global view to track all inbound and outbound traffic. It acts as a single switch for all policy engines and applications.

Programmatically Configurable

IT network managers can configure, secure, optimize, and manage SDNs. This process is quick and dynamic and lets IT personnel write their own programs. Automated SDNs don’t rely on proprietary software.


The SDN architecture offers scalability which is essential in today’s environment. It’s scalable because this network’s development occurs in stages. This reduces business costs since you won’t need to pay for upgrades or new software.


Increased security is now an essential part of every network. The SDN can detect unusual network behavior.

It then responds in real-time to neutralize the threat. The SDN blocks all devices nearest the source of the attack.

SDN Management

Has your business already started to transition to next-generation virtual environments? If so, integration of the SDN will provide an end-to-end view of all network services. It uses a Web interface that shows you both your physical and virtual network processes.

These virtual networking solutions increase the IT department’s service capabilities. They now have the ability to do the following:

  • Analyze hybrid WAN performance and optimize application delivery to the users
  • Identify and document disparate metrics from a single-service view of the SD-WAN
  • Support application performance
  • Support the system’s infrastructure
  • Establish and automate desired baseline metrics for performance
  • Create predictive alerts to detect problems in the service performance
  • Interconnect performance measures across applications, networks, and security
  • Develop rapid intelligence scaling across the entire global enterprise

All these abilities benefit both parties in the B2B partnership. This allows clients to maintain a competitive edge in their market. They're able to control costs and optimize services with streamlined management.
