He received the IEEE Communications Society Best Tutorial Paper Award in 2008, a Friedrich Wilhelm Bessel Research Award from the Alexander von Humboldt Foundation in 2015, as well as a DRESDEN Senior Fellowship in 2016 and in 2019.


Abstract: Agility: Mobile Edge Computing (MEC) brings the benefits of cloud computing, such as computation, networking, and storage resources, close to end users, thus reducing end-to-end latency and enabling various novel use cases.  However, frequent user mobility makes it challenging for the MEC to guarantee the close proximity to the users. To tackle this agility challenge, the underlying network has to be capable of seamlessly migrating applications between multiple MEC sites.  This application migration requires the quick and flexible migration of the application states without service interruption, while minimizing the state transfer cost.  We give an overview of the Flexible And low-latency State Transfer (FAST), the first programmable state forwarding framework. FAST flexibly and directly forwards states between source instance and destination instance based on Software-Defined Networking (SDN).

Reliability: Existing Network Function Virtualization (NFV) service placements that reuse existing network functions either reuse an entire Service Function Chain (SFC) or only individual network functions while ignoring the chain configuration cost for configuring the SFC traffic steering and ignoring the reliability of the network functions.  Also, the Mobile Edge Cloud (MEC) frameworks that are required to implement an NFV service placement should ideally seamlessly cooperate with the various existing NFV Management and Orchestration (MANO) frameworks. However, the existing MEC frameworks lack multi-MANO support.  We give an overview of the novel Subchain-Aware NFV service Placement (SAP) optimization model that accounts for the configuration cost for stitching together reused network functions to an SFC and strives to reuse existing subchains of consecutive network functions (with already deployed SFC traffic steering), while accounting for the recovery cost of network functions with limited reliability. Furthermore, we sketch the novel Automated Provisioning framework for MEC.
