Wladislaw Gusew, M.Sc.

About me

Since January 2015, Wladislaw Gusew is affiliated with the DFG-funded graduate school SOAMED and works as research assistant at the Computer Engineering group at the Humboldt University of Berlin, Germany.

Wladislaw Gusew obtained a B.Sc. in Applied Computer Science in the Natural Sciences from the University of Bielefeld, Germany in 2012. He continued his studies at the Humboldt University of Berlin, where he received a M.Sc. in Computer Science in 2015. His Master's thesis is about benchmarking classification algorithms for network packet processing.

Research interests

Software-defined Networking

Software-defined Networking (SDN) is a paradigm enfolding a dynamic management of network resources by making each network node programmable. Essentially, SDN is defined as a physical separation of the control plane from the data plane in network devices, such as routers and switches. In dynamic computing environments, which can be found at cloud service providers, SDN is already in use. One protocol standard for communication between SDN-ready devices is OpenFlow.

Scientific Workflows

Today's scientists of several academic disciplines utilize scientific workflows for a sophisticated analysis and calculation of scientific data, for instance, astronomical observations, biological genomic sequencing, or simulations regarding elementary particles in physics. A scientific workflow is represented by a directed, acyclic graph (DAG), in which individual tasks are represented as nodes. Connections between each node determine data interdependecies, which are relevant for the (distributed) execution of a workflow by processing data sequentially and/or concurrently.
