Research Interests

Software-Defined Networks

Software-Defined Networking (SDN) is an emerging architecture that is dynamic, manageable, cost-effective, and adaptable, making it ideal for the high-bandwidth, dynamic nature of today’s applications. This architecture decouples the network control and forwarding functions enabling the network control to become directly programmable and the underlying infrastructure to be abstracted for applications and network services. 

P4: Programming Protocol-Independent Packet Processors

P4 is a programming language for controlling packet forwarding planes in networking devices, such as routers and switches. In contrast to a general purpose language such as C or Python, P4 is a domain-specific language with a number of constructs optimized for network data forwarding.

Congestion Management

Network congestion in data networking and queueing theory is the reduced quality of service that occurs when a network node or link is carrying more data than it can handle. Typical effects include queueing delay, packet loss or the blocking of new connections. A consequence of congestion is that an incremental increase in offered load leads either only to a small increase or even a decrease in network throughput.

Project Work

KITOS

KITOS develops concepts for the management of TSN-based networks supported by artificial intelligence (AI).
In the project, the consortium partners develop AI algorithms that give networks the necessary dynamics and reliability for industry 4.0 scenarios and allow users to use them easily and without in-depth network or AI knowledge. Intelligent tools support decision making, allow more efficient use of resources and enable higher performance configurations. For active operation, the network management is secured against failures with AI-supported error detection and adaptation mechanisms.

CoMa (Congestion Management for Packet-Based Communication Networks)

In this project, new concepts for congestion management in packet-based communication networks, in particular for IP technology, are developed and investigated. Congestion management detects congestion in a network and resolves it. Challenges are delay limitation, high resource utilization, and fair bandwidth partition in case of congestion.
