Part II (continued from Monday afternoon)

Today, one of the hottest topics of ICT is the integration of network and cloud fostered by virtualization at various layers. While virtualization of compute and storage resources has been advancing since many years, large scale network virtualization has just recently been enabled by software defined networking (SDN) and its use of network abstractions. Even more recently, fundamental network functions (not just subscriber data and control plane functions but also high touch packet processing functions) are candidates to migrate into the cloud.

Many standard organizations (Open Networking Forum – ONF, ETSI Network Function Virtualization – ETSI NFV and IETF-nvo3  and IRTG-SDNRG ), open source initiatives (OpenStack and OpenDaylight) and research programs (e.g., EU FP7 Call 11, GENI, US Ignite) work on topics closely related to network virtualization, and operators are also attracted to the integration of network and cloud as a way for fostering their business.  

The aim of the two half days workshop is to

  • Introduce standard organizations’ work related to network virtualization (ETSI NFV, ONF, IETF);
  • Discuss EU FP7 Projects’ visions and use-cases related to virtualization;
  • Give an overview about OpenDaylight and ON.lab’s ONOS – as controllers to virtualization;
  • Discuss in a panel how virtualization changes business models and the boundaries among players


  • Ali Al-Shabibi (ON.lab): An overview of ONOS - motivation for it, technical considerations and architectural choices, current status, next steps
  • Konstantinos Katrinis (IBM): IBM approach in network virtualization (openDOVE/SDN-VE)
