Presence of 5G-Ex on the 101st IETF meeting in London

March 17-23, 2018 the 101st IETF meeting took place in London.


IETF is one of the key standards development organizations (SDOs) where 5GEx is actively contributing. During this meeting, different contributions were made from 5GEx partners such as “Network Virtualization Research Challenges”,  “Multi-domain Network Virtualization” and  ”Common operation an management of network slicing” .

5GEx paper presented at OFC 2018 in San Diego, CA, USA

A paper titled “On the Scalability of Connectivity Services in a Multi-Operator Orchestrator Sandbox” was presented on March 12 at the Optical Networking and Communication Conference & Exhibition (OFC).
The paper investigated the performance of a multi-domain orchestrator (MdO) deployed in the 5GEx Sandox. Results showed how the MdO prototype scales well with the number of domains advertised and connectivity services provisioned.

OFC is the largest global conference and exhibition for optical communications and networking professionals.
In San Diego OFC showcased the latest innovations in the field,  with more than 15,500 attendees, 700+ exhibitors from 65 countries, and over 850 peer-reviewed technical sessions.

Invitation to the 2nd 5G-Ex Industrial Workshop @Network Virtualization Europe Conference 22-24 May, 2018

We are pleased to announce the second 5GEx Industrial Workshop, organized by the 5GEx project, a H2020 5G-PPP phase 1 project. The workshop is part of the 6th Annual Network Virtualization Europe conference (May 22-24, Madrid) organized by KNect365 TMT, an Informa business.

The workshop focuses on the current and future perspectives of MANO, the management and orchestration functional layer for the NFV-enabled telecommunication infrastructure. A prominent focus will be on the interworking of NFV-enabled service providers in the forthcoming 5G networking landscape, both from a business and technical viewpoint.

Beside the workshop, 5GEx will be present with demonstrations, whitepapers and personal presence to foster the exchange of vision and results with all the interested conference participants. We look forward to meet you at the workshop, for discussing with you the 5GEx vision as well as sharing your ideas to transform the 5GEx concept into concrete innovation and growth for your business.

More details, schedule, topics will be updated soon.


Presence of 5G-Ex on the 100th IETF meeting in Singapore

November 11-17, 2017 the 100th IETF meeting took place in Singapore.
IETF is one of the key standards development organizations (SDOs) where 5GEx is actively contributing. During this meeting, different contributions were made from 5GEx partners:

- “Network Virtualization Research Challenges” . This document, adopted by the Network Function Virtualization (NFV) research group, identifies and describes open research challenges for network virtualization. One of the documented challenges is precisely multi-domain orchestration. The NFVRG issued a Research Group Last Call, which resulted in some reviews that have been addressed by the authors. Next step is requesting publication of it as Request For Comments (RFC) to the IETF. The authors (UC3M, Telefonica and Interdigital) will work on some minor updates of the contribution
before this final step.

- UCL presented “”Network Slicing Supported by Dynamic VIM Instantiation” at the NFVRg session. Dr. Stuart Clayman received quite interesting questions and feedback during his presentation, that you is available here

- The network slicing effort being driven by Prof. Alex Galis is now focusing on “Common operation an management of network slicing” (COMS), which got time to present during the Operations and Management Area Working Group session of the meeting. The presentation is available here. A 5GEx specific use case was presented as an example of the need of COMS efforts at IETF.

There were other interesting presentations for 5GEx during the week, as for example: “Considerations on Network Virtualization and Slicing

Showcasing the integrated 5G-Ex system with robotics control demo at IEEE NFV-SDN

A successful 5GEx demonstration was delivered at the 3rd IEEE Conference on Network Function Virtualization and Software Defined Networking at Berlin, Germany, 6-8th November 2017 (

The orchestration was showcased on an infrastructure consisting of multiple administrative domains, which were represented by Docker Domains as computing resources and OpenFlow switches as transport domains. The resilient robotics control service was decomposed by the VNF Manager into a duplicated PID controller logic loop, which can be executed in Docker containers. The multi-domain orchestration system reserved independent computing resources for the controllers and disjoint transport paths for their traffic. The balancing robot was receiving control information through Wi-Fi from both PID controllers.
