Leveraging Software-Defined Networking


Leveraging Software-Defined Networking


Outdated security networks, slow IT function processing rates, and high network security risks are among the many concerns companies face into today’s age of information technology.  By leveraging software-defined networking, enterprises can alleviate many of their fears and worries by witnessing more efficient control of their IT resources, higher flexibility, and not to forget, greater security protection from data breaches.  However, the question many IT executives may be wondering is, what exactly is software-defined networking? And what advantages can it bring to their organization?  Let’s look into these topics in detail.

Software-Defined Networking (SDN)

In essence, an SDN allows a company’s network administrators to utilize higher functionality of network services. Through SDN, they can decouple the network’s control plane across multiple hardware and integrated circuits, allowing them to gain centralized traffic control without needing to use various individual switches.  Communication between the control plane and the data plane is programmed using the OpenFlow mechanism, through which the company can achieve some advantages. These are as follows:


1. Centralized Networking

SDN allows network administrators to centralize all network functions, leading to more efficient management of all critical activities and processes. The burden of VLANs, which is becoming more inextricably linked with LANs, is leading network functions to appear as a knot of wires, owing to the highly fragmented network. This makes it far more difficult for network administrators to manage a sea of different dependencies, increasing their service delivery time and reducing work efficiency.

However, through SDN, they can significantly speed up the process through higher network agility, allowing them unprecedented ease of accessing all network devices centrally.


2. Comprehensive Enterprise Management

The configuration of SDN is broad enough to support big data processing requests, saving network administrators the time and resources in setting up new virtual machines and applications.  SDN can also accommodate virtual and physical switches all from a single access point, making it far efficient and more accessible for network administrators to manage all the processing requests under one domain.


3. Robust Network Security Protection

One of the other more important benefits of SDN is higher security protection against cyber attacks and data breaches. Due to centralized control, network administrators can better detect and manage all known security threats under a single window. SDN allows all firewall systems, encryption technologies, multi-factor authentication controls, and stringent user access policies to be implemented without requiring to manage it on an individual basis.  The results are a more uniform security implementation across the entire enterprise network.


4. Reduces Operational Costs

The centralized control arising from the use of SDN leads to some cost-efficiencies. Among these include higher administrative efficiency, greater virtualization control, higher server utilization, and other operational cost advantages.  Firms can achieve this mainly because less time and resources are being devoted to performing administrative functions, which can be automated and supervised using SDN.


5. Seamlessly Integrates with Cloud Networks

The integration of SDN with cloud networks is another crucial advantage that companies can achieve. Cloud computing is becoming a foundation for many businesses, and through SDN, firms can avoid the challenge of managing two separate networks that is very likely to result in management problems and slow processing activities.  SDN can allow network administrators to leverage all critical cloud functions from a centralized access panel and ensure their corporate data requirements go hand in hand with cloud efficiencies.
