Application-Defined Networking

Definition of Application-Defined Networking

Application-Defined Networking (ADN) is a networking approach that focuses on tailoring network behavior and resources according to the specific needs and requirements of the applications running on it. By incorporating software-defined networking principles, ADN allows for centralized control and configuration of network components, such as routers and switches, to optimize performance, manageability, and security. This way, it ensures a more adaptive and efficient network infrastructure that can dynamically respond to the unique demands of various applications and services.


The phonetic breakdown of the keyword “Application-Defined Networking” is:æplɪˈkeɪʃən dɪˈfaɪnd ˈnɛtˌwɜrkɪŋ

Key Takeaways

  1. Application-Defined Networking (ADN) enables applications to have greater control over their network resources by dynamically allocating and managing these resources based on the specific needs of the applications.
  2. ADN improves network flexibility, adaptability, and efficiency by allowing applications to directly influence network devices and protocols to optimize routing, load balancing, and other network functions in real-time.
  3. By enabling better communication between applications and the underlying network, ADN integration can facilitate improved performance, scalability, and security for various applications, particularly in cloud and data center environments.

Importance of Application-Defined Networking

Application-Defined Networking (ADN) is an important technology term because it represents a shift in the way networks are managed, allowing for increased efficiency, flexibility and control.

With ADN, networking functions are tailored to the specific needs and requirements of applications, rather than being defined by static configurations.

This approach enables organizations to dynamically deploy, monitor, and adjust networking resources to optimize application performance and user experience, all while reducing operational costs.

Moreover, ADN empowers software developers to have more direct influence over network configurations, which leads to better alignment between networking infrastructure and application demands.

Overall, Application-Defined Networking plays a crucial role in supporting modern software-defined environments and driving innovation within the realm of networking technology.


Application-Defined Networking (ADN) serves as a mechanism to optimize network performance and streamline data flow by tailoring network configuration to the specific needs of individual applications. As the digital landscape evolves, the demands on network infrastructures expand, making it necessary to implement dynamic controls.

ADN bridges the gap between applications and the underlying network to deliver adaptability, efficiency, and on-demand resource provisioning. With customization at the very core of ADN, network operators can gain better insights into traffic patterns and requirements, which in turn can drive intelligent allocation and configuration of network resources, ensuring optimal performance for the varying workloads of different applications.

One of the fundamental aspects of ADN revolves around the growing need for agile and diverse network environments that cater to various applications such as video streaming, cloud computing, or IoT deployments. By automating network resource management, ADN enables quick response to changes in application demands and aligns the network behavior with the specific goals of a given application.

This not only increases the overall efficiency but also allows for enhanced scalability, security, and reduced operational expenditure. Moreover, with the incorporation of techniques like software-defined networking and network function virtualization, ADN integrates seamlessly into the existing ecosystem, transforming traditional networks into programmable, flexible, and agile frameworks that can neutralize the ever-increasing challenges faced by businesses in today’s digital world.

Examples of Application-Defined Networking

Application-Defined Networking (ADN) is an advanced networking technology that enables real-time network customization, management, and optimization for various applications. It has been used in different industries and scenarios to cater to different usage requirements.

Data centers and cloud providers: ADN technology is widely used in data centers and cloud infrastructure to optimize resource usage, reduce latency, and improve overall network performance. By integrating ADN with their management systems, providers like Amazon Web Services, Microsoft Azure, and Google Cloud Platform can optimize the network environment for each application, ensuring faster, secure, and reliable connections.

Internet of Things (IoT): As more devices are connected to the internet, managing the traffic and communication between these devices becomes a challenge. ADN can be employed in IoT networks to make on-the-fly updates for applications, enable efficient routing, and manage resources. For example, the ARTIK Cloud platform developed by Samsung, utilizes ADN to build and manage IoT applications.

Telecommunications and mobile network operators: Telecommunication companies are continually evolving to meet the needs of increasing data consumption, improving connectivity and ensuring quality of service for their customers. By using ADN, operators can manage bandwidth allocation tailored to the requirements of various applications such as video streaming, VoIP, online gaming, and more. In 2015, NEC and NetCracker Technology introduced an ADN solution that allowed service providers to optimize bandwidth based on the applications used by their customers.

Application-Defined Networking FAQ

What is Application-Defined Networking?

Application-Defined Networking (ADN) is a network configuration approach that focuses on optimizing the network based on the needs and requirements of specific applications. This allows applications to request and influence network resources according to their performance demands, leading to improved efficiency.

What are the benefits of Application-Defined Networking?

ADN offers numerous benefits, including better network performance, optimized resource utilization, increased flexibility, and enhanced security. By managing the network based on application requirements, organizations can ensure optimal performance and improve overall productivity.
