SDNGR Software-Defined Networking Research Group

However, I can provide you with an overview of software-defined networking (SDN) and its research aspects, which might help you understand the general concept and ongoing research in the field.

Software-defined networking (SDN) is an architectural approach to network management and control that aims to make networks more programmable, agile, and adaptable. It separates the control plane from the data plane in network devices, enabling centralized control and management of the entire network infrastructure.

SDN research groups and organizations typically focus on studying various aspects of SDN, including its architecture, protocols, algorithms, security, performance, and applications. These groups often explore innovative ideas and develop solutions to address the challenges and opportunities presented by SDN.

Some common research areas within SDN include:

1. Network Programmability: Investigating new programming models, languages, and frameworks to facilitate the development and deployment of network applications on top of SDN architectures.
2. Network Control and Management: Designing efficient control algorithms and protocols for managing and orchestrating network resources in SDN environments. This includes topics like network virtualization, traffic engineering, routing, and Quality of Service (QoS) management.
3. Security and Privacy: Exploring security threats and vulnerabilities in SDN deployments and developing mechanisms to enhance the security and privacy of software-defined networks. This includes topics like access control, authentication, encryption, and intrusion detection.
4. Performance Optimization: Developing algorithms and techniques to optimize the performance and efficiency of SDN networks, such as load balancing, resource allocation, and traffic management.
5. Network Function Virtualization (NFV): Investigating the integration of SDN with NFV to enable flexible and scalable network services. NFV involves virtualizing network functions and running them on standard hardware, decoupled from specific network devices.
6. SDN Applications and Use Cases: Exploring real-world applications and use cases of SDN, such as data center networking, wide-area networks, Internet of Things (IoT), 5G networks, and edge computing.

Research groups and organizations working in the field of SDN often collaborate with industry partners, academic institutions, and standardization bodies to share knowledge, conduct experiments, and develop standards that promote the adoption and advancement of SDN technologies.

Please note that if the "SDNGR" group you mentioned is a recent development or a specific research group within a particular institution, it may not be covered in my training data, and I apologize for the lack of information.
