NFV and OpenStack

  1. 1. NFV and OpenStack Marie-Paule Odini – Distinguished Technologist HPE Corporate CT Office – CMS/CSB November 2, 2015
  2. 2. What is NFV: Network Function Virtualization – Leverage IT virtualization techniques for telecom functions • Use standard servers and storage • Applicable to telco network functions • Initiative from Tier 1 Operators & Vendors launched as a new Industry Specification Group (ISG) in ETSI – Key Benefits • Reduced equipment costs • Faster time to market • Resource sharing • Targeted service introduction • More flexible, programmatic operations virtualize network functions: from Home or Enterprise Gateway to Access/Core telecom network & Data centers
  3. 3. Service Providers are Driving NFV © Copyright 2015 Hewlett-Packard Development Company, L.P. The information contained herein is subject to change without notice. HP Confidential - For training purposes only. They are demanding new technology, rather than vendors pushing it …who face market pressuresCSPs… Telecom leaders are defining requirements and architecture for virtualization of network functions Exploding demand • In 2014:  Global mobile data traffic grew 69%  497M mobile devices added  Video services dominated the network at 55% Shifting landscape • Expanded access channels (Wireless, Internet, TV, satellite) • Services business model changing (e.g. free messaging) • Internet of Things (IoT), especially wearables Growing CapEx and OpEx • Flat or declining user fees • Increasing application usage and bandwidth demands • OpEx increasing ~3% annually
  4. 4. Latest Joint-Operator NFV White Paper • Published October 14, 2014 • Detailed description of second release of NFV ISG documents • Provides latest operator perspectives on industry progress on NFV implementation • Highlights the importance to evolve network management systems to accommodate dynamic nature of NFV • Encourages academic research and evolution of teaching courses Paper available on ETSI NFV Portal: Slide 4 30 operators contributed

  26. 26. NFV and Openstack example of requirements Nf-Vi, Vi-Vnfm, Nfvo-Vi 26 • Multi-hypervisor support • Different virtualization model (ie docker, Linux) • Support legacy, bare metal • Support DPDK CPU, SRIOV NIC • Expose NW load balancer and other functions • Support HA , 5 9s • Support Secure Boot , certification • Support resource reservation (prior to instantiation) • Map pCPU with vCPU (dedicated CPU – pinning) • Support NUMA placement (memory access perf) • Expose localization of resources • Expose resource catalog • Expose resource metrics • Release backward compatible • Rollback • etc
  27. 27. NFV & OpenStack ?? Ex Security Security-specific? 27 Over 1.7M lines of code ~6meters ~6metersor20 feet ? How can I ensure there is no security breach in 1.7M lines ? ? How does Openstack prevent back doors ? ? How does Openstack support secure boot, certified VM? ? How can I define security rules for an SDN application to change a flow table on an SDN switch that is provided by a IaaS Provider that may change along the life of the service ? ? How can I ensure that the memory I am sharing will not be accessed by somebody else ? ? Can I present the system admin to access my personal data etc Many blocks interact with Keystone Keystone is not the only entity that deals with security Keystone deals with security & policies, but NFV will need end to end security & policies across end to end network, at ?NFVO level : how to synchronize? etc
