Recap of the 2nd 5GEx Industrial Workshop

Our workshop was part of the 6th Annual  Network Virtualization Europe conference (May 22-24, Madrid) organized by KNect365 TMT, an Informa business. We supported the organization of the “Track B: Service Assurance & MANO” and were present as supporting organization on all communication material, which helped a lot to attract people joining presentations, discussions and the demonstration of the 5GEx GiLAN use case.

Our two presentations were given by Hakon Lonsethagen on business aspects in a “Multi-provider services and automated orchestration by the 5G Exchange Service Layer” (summary of section 3 and 4 of D2.3) and by Dr. Carlos J. Bernardos on architecture aspects with detailed explanation on the example use case GiLAN (“Roaming in an NFV-enabled multi-operator world”). Both presentations have been very well received by the audience. Especially the first one was reflected in the Service Assurance & MANO track in the panel discussion on “Orchestration Strategy and Challenge”. The panel included a mixture of 5GEx partners with Telefonica, Telenor and Telecom Italia and leading industrial players like CableLabs or EXFO.  Some of the discussed aspects are:

  • Dealing with continuous development leads to frequently new aspects and problems (e.g. problems in ETSI NFV standards for closed loop orchestration)
  • Status of maturity of virtualized network functions (agreement that it improves)
    • Education and training is very important, change of people minds underestimated
    • Change of organizational culture is still important, transformation is not a problem of weeks or months
      • Resiliency is of higher importance in telco word than in IT world, this should especially regarded by developers
      • Adoption of mature technologies takes sometimes time, e.g. TCP flow control is debated for several decades now

The high-level introduction of the 5GEx architecture and presentation of the GiLAN use case was very successful. There have been a lot of employees of mobile operators at the conference (in fact, these persons are representing 20-30% of all mobile customers in the world) and the GiLAN use case attracted their interest. So, we had counted in total 40 visitors, ten demos and gave away 25 white papers. The feedback was very positive, acknowledging the interesting idea and accepting that multi-provider NFV is something of importance for the future. There have been many detailed discussion, ranging from the detailed technical standards for mobile Internet connectivity to options in deploying the virtualized network functions.

 

Invitation to the 2nd 5GEx Industrial Workshop

We are pleased to announce the second 5GEx Industrial Workshop, organized by the 5GEx project (www.5gex.eu), 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. Informa is a leading international business intelligence, academic publishing, knowledge and events group. . The conference focuses on bridging between NFV operators, function developers and suppliers of the emerging NFV infrastructures. The workshop is held as a session about MANO on the first conference day, directly following the opening and keynote speakers. Details on the conference and agenda can be found here: https://tmt.knect365.com/virtualization-sdn-europe/

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. Håkon Lønsethagen (Telenor) will present the latest analysis and results on business aspects like community models, community creation and operation, quality of service definitions and quality-enabled services. Carlos J. Bernardos (University Carlos III of Madrid) will present roaming in an NFV-enabled multi-operator context, focusing on technical aspects and latest MANO reference implementations in various open source frameworks, including the results of the 5GEx project. Finally, Diego Lopez (Telefonica) will lead a 5GEx organized panel, which will conclude the session and discuss the state, missing pieces and next steps for MANO including the multi-domain 5GExchange vision.

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.

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

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

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.

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 (http://nfvsdn2017.ieee-nfvsdn.org/).

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.
