Title: Network Function Virtualization and Flexible Service Chaining in Multi-Domain/Provider Environments: Recent Developments


Cloud networks provide various services on top of virtualized compute and storage resources. The flexible operation and optimal usage of the underlying infrastructure are realized by resource orchestration methods and virtualization techniques developed during the recent years. In contrast, service deployment and service provisioning in carrier networks have several limitations in terms of flexibility, scalability or optimal resource usage as the built-in mechanisms are strongly coupled to the physical topology and special purpose hardware elements. Network Functions Virtualization (NFV) opens the door between cloud and carrier networks by providing software-based telecommunication services which can run in virtualized environment on general purpose hardware. Our goals are to unify software (NFV) and network (service chaining) resource management into a common framework that could be used for end-to-end service creation.

In the framework of the EU-FP7 UNIFY project we created novel architecture supporting automated, dynamic service creation based on a fine-granular service chaining model, SDN and cloud virtualization techniques. As a sequel, in the scope of the EU H2020 5G Private Public Partnership program’s 5G Exchange project, we work on multi-provider extensions to enable dynamic NFV and SFC services across multiple provider domains.

The talk will summarize recent developments and some learning based on corresponding proof of concept prototype implementations.


RóbertSzabó, PhD is a master researcher at Ericsson Research, Hungary since 2013. At Ericsson, he is the technical coordinator of the EU-FP7 integrated project: Unifying Cloud and Carrier Networks (UNIFY) and the Project Coordinator of the H2020 5G-PPP 5G Exchange innovation action. He was the co-organizer of the “Network Virtualization” full day workshop at the Future Internet Assembly event, in Athens, Greece, 2014. He was the TPC co-chair of the Third European Workshop on Software Defined Networks (EWSDN) at Budapest, Hungary, 2014. Dr. Szabo has an associate professor position (part time) at the Department of Telecommunications and Media Informatics (TMIT), Budapest University of Technology and Economics (BME). He was the president of the Telecommunications Section of the Scientific Association for Infocommunications (HTE), Hungary (2005-2007). He was the deputy head of the TMIT, BME (2008-2010). He was the head of the High Speed Networking Lab (HSNLab), a research group at BME (2007-2012). His researches were supported by the János Bolyai Scholarship of the Hungarian Academy of Science (MTA). He was a member of the Future Internet Award jury between 2010 and 2013. He served in the TPC of several conferences and workshops. He is co-author of over 80 publications. His current research focus is on software defined networking (SDN), network functions virtualization (NFV) and service function chaining (SFC). He is one of the editors of the policy-based research management area draft at IRTF NFVRG.
