The main objective of the High speed networks research group is to design, implement and evaluate new mechanisms and architectures for efficient and flexible high-speed networks. Thereby, we consider packet-switched as well circuit-switched wide area networks. Our methods include simulation, protocol engineering, formal methods as well as digital systems design and experimental activities. We perform our work together with partners from industry and academia within national and international funded projects.

Our current research actitivies include the following four main areas: Resource allocation (Design and evaluation of efficient resilience and protection strategies for optical networks, Design and evaluation of network optimization strategies using rearrangement of resouces, Network virtualization strategies for efficient network usage and hit-less operation in maintanance scenarios) Network control (Evaluation and implementation of path computation devices for multi-layer and multi-domain networks, Design and evaluation of new control strategies for carrier grade Ethernet networks) Traffic measurement and characterization (Evaluation of new methods for flexible and precise traffic characterization, Design and evalution of novel methods to analyse packets out-of-sequence arrivals) High-speed node design (Digital systems design and implementation of a flexible router architecture, Design, implementation and evaluation of an energy efficient and high-performance packet buffer)
