The document discusses the Superfluidity project, part of the EU's Horizon 2020 initiative, aimed at developing a converged cloud-based 5G architecture to enhance mobile network capabilities. It outlines challenges in network function virtualization (NFV), contributions from various partners including Red Hat and telco operators, and future directions for open source contributions. Key objectives include reducing operational costs, improving service instantiation flexibility, and managing mixed workloads of virtual machines and containers in 5G networks.
Superfluidity, Infrastructure for mixed workloads in Mobile Edge Computing - Livnat Peer - OpenStack Day Israel 2017
- 1. Enabling 5G mobile networks through open source portfolio Livnat Peer, Red Hat June 2017
- 2. Agenda ● EU Projects ● Superfluidity Overview ● Superfluidity NFVO Architecture ● Red Hat Contributions ● Future directions
- 3. (H2020) EU Projects ● Horizon 2020 is the biggest EU Research and Innovation programme ever with nearly 80 billion Euros of funding available over 7 years (2014-2020) ● Emphasis on excellent science, industrial leadership and tackling societal challenges ● Make it easier for the public and private sectors to work together ● Ensure European produces world-class science and innovation ● Grands in different domains, for example : ■ Excellent Science (such as FET and Marie Curie actions) ■ Industrial Leadership (in Enabling and Industrial Technologies) ■ Information and Communication Technologies → (e.g., Advanced computing, future internet, robotics, …) ■ Smart, Green and Integrated Transports
- 4. Superfluidity Overview ● NFV challenges: ○ Long provisioning times ○ Wasteful over-provisioning to meet variable demand ○ Reliance on rigid and cost-ineffective hardware devices ○ Heterogeneity: ■ Traffic and sources ■ Services and needs ■ Access technologies with multi-vendor network components ○ Many others...
- 5. Superfluidity Overview ● Objective ○ Provide converged cloud-based 5G concept that ■ Enables mobile edge use cases ■ Empowers new business models ■ Reduces investment and operational costs ○ Consortium ■ Academia: CNIT, University Ben Gurion, University of Liege, University of Technology Dresden, University Politehnica of Bucharest ■ Telco Operators: British Telecom, Telefonica I+D, Altice Labs (Portugal Telecom) ■ Industry: Nokia Bell Labs France, Alcatel Lucent Israel, Citrix, Intel R&D Ireland, NEC, OnApp, Red Hat, Telcaria, Unified Streaming ○ Budget and duration: ■ Almost 8 million Euros ○ July, 1, 2015 ←→ March, 31, 2018
- 6. Superfluidity aims at achieving: Ability to instantiate services on the fly, Run them anywhere in the network (core, aggregation, edge) and Shift them transparently to different locations
- 7. 5G Networks: Reducing costs through virtualization Virtualization + control and data plane split: save operation costs, increases management flexibility

- 9. 5G Networks: C-RAN Centralized and virtualized BBU to save management and operation costs
- 10. 5G Networks: MEC TOF Applications can be deployed at the edge to take advantage of higher bandwidth and reduced latency EDGE CLOUD
- 11. 5G Networks: Big picture
- 12. Superfluidity NFVO Architecture Open Source based NFVO Architecture Red Hat contributions: ● Kuryr ● Neutron ● Openshift-ansible ● ManangeIQ
- 14. Red Hat Contributions ● Noisy neighbor problem ○ Neutron QoS to limit max bandwidth ● Speed up network connectivity ○ OVS-Firewall to remove linux-bridge + iptables overhead when connecting VMs to the Neutron networks ● Speed up reaction to workload fluctuations and consider physical resource limitations at the edge ○ Work on Kuryr to enable mixed containers and VMs deployments ○ Work on Kuryr to enable nested containers by leveraging Neutron Trunk ports support (VLAN-Aware-VMs) ○ Work on Kuryr to speed up container boot time when plugged into Neutron networks ● Multi-site and mixed environment management ○ Push ManageIQ as NFVO and enable ansible playbook execution support into it FIRSTYEARSECONDYEAR
- 15. Kuryr ● Added vlan trunk support (used in nested containers) ● Ports pool changes (being merged) **Absolute numbers are irrelevant given the hardware used for testing, the ratio between with/without pool is interesting
- 16. ManageIQ ● A management project that enables managing containers, virtual machines, networks, and storage from a single platform ● Manage IQ connects and manages to your existing clouds: OpenStack, Amazon EC2, Azure, Google compute engine, VMware, Kubernetes ● Gaps closed by Superfluidity ○ Adding the option to run a generic Ansible playbook to help us close some of the gaps, including instantiating containers in Kubernetes
- 17. Other Superfluidity contributions ● NEC work on reducing VM boot time, especially around uni-kernels ● “SplitBox: Toward Efficient Private Network Function Virtualization” university of Liege, Belgium ● “SymNet – Scalable Symbolic Execution for Modern Networks” - Security framework for static networking vulnerabilities analysis by UPB ● Intel’s contribution on applications’ KPI and scheduling impact ● Additional Kuryr work - ○ Kuryr heat templates to deploy master and worker VMs ○ Kuryr installation support at openshift-ansible playbooks ● Many other contributions...
- 18. Future Directions ● Keep contribution to open source projects/communities ● DPDK as a data plane speed up for containers using kuryr ● Related Kuryr enhancement: ○ Multi nic supports ○ Neutron networks creation from Kubernetes cli ● Focus on the MEC management problems (isolation, mutitenancy, …) for VMs and containers mixed environment

- 21. Osp Israel Abstract You sent: Superfluidity is a European Union research project that innovates in the 5G networks domain. It's goal is to design a converged cloud-based 5G architecture which would enable instantiating services on-the-fly, running them anywhere in the network (core or edge) and shifting them transparently to different locations. 18 partners are contributing to the project, including leaders from the IT and Telco industries and from the academia.In this session we'll understand the MEC architecture which supports mixed workloads of VMs and containers sharing one networking infrastructure. We’ll discuss side by side deployment of OpenStack and Kubernetes while leveraging Kuryr to build a single networking infrastructure.
