Software Defined Networking Vs Traditional Networking

What is Software Defined Networking?

In the realm of contemporary networking, understanding the fundamental concepts of Software Defined Networking (SDN) is pivotal. SDN represents a paradigm shift in network management, characterised by the separation of the control plane and data plane. In essence, the core concept of SDN involves decoupling the control and data forwarding functions, allowing for centralised programmable control over the network.

What is Traditional Networking?

On the flip side, traditional networking represents the legacy infrastructure that has been the backbone of communication systems for decades. Traditional networking operates on a hierarchical architecture and relies on device-centric configuration. The core concept involves routers and switches that make forwarding decisions based on predefined rules within the devices themselves.

Distinctions between Software Defined Networking and Traditional Networking

In Software Defined Networking, a notable characteristic is the separation of the control plane and data plane. The control plane and data plane separation in software defined network allows for centralised control over network decisions, where the control plane manages traffic flow and forwarding decisions are executed by the data plane. This separation provides a level of flexibility and programmability not achievable in traditional networking, where both functions are tightly integrated within network devices.

Programmability and automation represent another critical distinction. Software Defined Networking enables programmability through open APIs, allowing for the creation and implementation of custom applications that control network behaviour. Automation, in turn, streamlines configuration and management processes, reducing manual intervention and the likelihood of errors. In contrast, traditional networking often relies on manual configurations for network devices, limiting the speed and agility with which changes can be implemented.

Centralised versus distributed network control is a crucial consideration in understanding the distinctions between Software Defined Networking and traditional networking. SDN embraces centralised control, where network decisions are made from a central controller. This centralised approach facilitates easier management and coordination of network-wide policies. Traditional networking, on the other hand, typically adopts a distributed control model, where decisions are made at individual network devices. This can lead to potential challenges in maintaining consistency and coherence across the entire network.

Impact on Efficiency and Flexibility of Network Infrastructure

Moving on to the impact on the efficiency of network infrastructure, Software Defined Network introduces dynamic resource allocation, allowing for on-the-fly adjustments to network resources based on real-time demand. This adaptability enhances efficiency and resource utilisation compared to traditional networks that may struggle to dynamically allocate resources. Additionally, SDN excels in streamlining configuration and management through automation, contributing to more efficient operations.

Allied Telesis offers Software Defined Networking solutions that centralise network management and enable dynamic configuration changes through software. This approach enhances flexibility by decoupling network control from hardware, allowing for rapid adaptation to changing business needs.

In terms of flexibility, SDN’s adaptability to changing network conditions is a significant advantage. SDN allows networks to adapt in real-time to varying conditions, optimising performance and responsiveness. Enhanced agility in service provisioning is another hallmark of SDN, as it enables rapid deployment and modification of network services. Conversely, traditional networks may face challenges in adapting to dynamic requirements due to their inherently static configurations, potentially resulting in slower response times and less adaptable services.

Allied Telesis’s Network AI solutions are designed to scale easily, allowing businesses to expand their network infrastructure without major disruptions. This scalability ensures that the network can grow alongside the organisation’s needs, improving flexibility.
