The 2nd International Workshop on Software-Defined Networking and Network Function Virtualization for Flexible Network Management (SDNFlex 2017) will be held in Göttingen, Germany in conjunction with NetSys 2017, which is technically co-sponsored by IEEE Communications Society (IEEE ComSoc), Information Technology Society within VDE (ITG VDE), the German Informatics Society (GI) and in-cooperation with ACM SIGCOMM. The workshop is supported by the RWTH Aachen, the University of Würzburg, the Technical University of Darmstadt and the EUREKA / Celtic-Plus cluster project SENDATE. It is further endorsed by the ITG section 5.2.1 (System Architecture and Traffic Engineering), the ITG section 5.2.2 (Network Security) and the ITG section 5.2.4. (IP and Mobility).
Network management currently undergoes changes towards more flexible network management. This trend is stimulated by Network Virtualization and Software Defined Networks (SDN) that emerged in recent years. These technologies allow networks to be run in a more flexible and cost efficient manner, e.g., by increasing network resource utilization and by decreasing operational costs. As an emerging topic, Network Function Virtualization (NFV) allows even further flexibility by migrating network functions (e.g., DHCP, PPPoE) from dedicated hardware to virtual machines running on commodity hardware. Virtualized network functions are appealing to network operators since they can be migrated and flexibly adapted to current demands.
The newly achieved flexibility in network management, particularly for NFV, opens a set of currently unresolved key questions concerning i) reliability, ii) service orchestration iii) function placement, and iv) performance. How to operate virtualized network functions in a reliable manner by providing redundancy and load balancing? Can virtualized network functions provide performance figures required for network operations and how can such virtualized services be benchmarked and compared? Where should network functions be placed to optimize the network subject to different design criteria? How can services be orchestrated? How can network monitoring be adapted to such flexible networks? This workshop aims at addressing these and similar questions in virtualized networks.
Topics of interest for submissions include, but are not limited to:
- SDN/NFV architectures, applications, and use cases
- Network monitoring and QoE
- Reliability of virtualized network functions
- SDN/NFV-based service orchestration
- SDN/NFV-based network deployment and management
- Business considerations and economic aspects
- SDN/NFV security
- Theoretical foundations of SDN/NFV networks
- Network Operating Systems and Languages
- SDN in Mobile and Wireless Networks
- Network Service Chaining

Title: Secure Networking for Distributed Telco Clouds
Future networks, like 5G mobile networks, are expected to fully adopt the new networking paradigms – SDN and NFV. At the same time, new use cases like vehicular communication or Industry 4.0 put high demands on the availability and integrity of communication networks. So, the security implications of using SDN and NFV are of paramount importance. On the one hand, there are clearly security challenges – new threats that must be mitigated. On the other hand, SDN and NFV leverage new security solutions, such as the creation of isolated network slices tailored to the (security) needs of different applications or verticals.
Taking 5G mobile networks as a use case, this talk gives a survey on the new security challenges and opportunities, and shows how secure 5G networks can be built on an infrastructure of distributed telco clouds.
Speaker: Peter Schneider (Nokia Bell Labs)
After receiving his diploma in mathematics, Peter started his professional career at Siemens, as a researcher on new software architectures. For several years, he worked on the research and prototyping of innovative communication solutions. Later, he became a systems engineer for the IP based mobile core network, working on various aspects of the IP technology, in particular on IP security, deep packet inspection and IP network reliability. Since 2007, he is focusing on network security research. Currently, he is a senior expert for mobile network security in the Security Research Team at Nokia Bell Labs. In this position, he has been involved in various security research projects including publicly funded international projects. His research interests include security for SDN and the telco cloud and the overall security architecture of future 5G networks. Peter co-chairs the VDE/ITG technical working group 5.2.2 on communication network security.
