NFV is "network function virtualization" and is a hot topic in virtualization and cloud infrastructure. This presentation walks through what NFV is and how the ManageIQ community could potentially integrate with various NFV implementations. For more on ManageIQ, see http://manageiq.org/

Design Summit - NFV BoF - Dave Neary
- 1. NFV and ManageIQ Dave Neary Open Source and Standards, Red Hat October 8, 2014
- 2. What is NFV? “NFV is a network architecture concept that proposes using IT virtualization related technologies to virtualize entire classes of network node functions into building blocks that may be connected, or chained, together to create communication services” 2 Dave Neary, Red Hat Wikipedia: http://en.wikipedia.org/wiki/Network_Functions_Virtualization
- 3. Hold on... what is NFV, again? 3 Dave Neary, Red Hat
- 4. Lost in a sea of acronyms CDN NFV CG-NAT AAA SBC ETSI NFV ISG IPSec MANO IMS SLA 4 Dave Neary, Red Hat VIM EPC VNFi DPI vCPE MME SGSN PDN-GW RNC eNode B QoE BNG VPN HLR/HSS OSS/BSS BRAS C-RAN VNFs
- 5. No, really... what is NFV? Telcos are replacing hardware with VMs 5 Dave Neary, Red Hat
- 6. Why do telcos care? ● Enables increased agility ● Market pressures are reducing margins and increasing customer demand for new services ● Reduced CapEx ● Consolidation of custom H/W to industry-standard servers ● Promise of reduced OpEx 6 Dave Neary, Red Hat
- 7. What is a network function? 7 Dave Neary, Red Hat
- 8. “Middleboxes” ● Act on data going through the network ● Examples: Load balancer, gateway, IDS, VPN endpoint, NAT, firewall ● Not just telco stuff 8 Dave Neary, Red Hat
- 9. Telco services 9 Dave Neary, Red Hat
- 10. Top use-cases ● IMS, EPC, SDB: Cellular, telephone, TV, video streaming, VoIP, 3G/4G data ● CPE: Customer Premises Equipment – telco equipment on-site (set-top boxes) ● Many others to choose from! 10 Dave Neary, Red Hat

The NFV-Infrastructure can span across several locations, e.g. places where data centres are operated. The network providing connectivity between these locations is regarded to be part of the NFV-Infrastructure. A functional block that manages the Network Service (NS) lifecycle and coordinates the management of NS lifecycle, VNF lifecycle (supported by the VNFM) and NFVI resources (supported by the VIM) to ensure an optimized allocation of the necessary resources and connectivity. A functional block that is responsible for the lifecycle management of VNF. A functional block that is responsible for controlling and managing the NFVI compute, storage and network resources, usually within one operator’s Infrastructure Domain (e.g., NFVI-PoP).

- 17. ETSI ● ETSI NFV ISG = European Telecommunications Standards Institute NFV Industry Standards Group ● Defines use-cases, terminology and interfaces for a hypothetical NFV platform ● Started European, but most telcos, NEPs and many software vendors have presence ● NFV white paper and use-cases seeded both OPNFV and OpenStack NFV team 17 Dave Neary, Red Hat
- 18. OPNFV ● Linux Foundation hosted project ● Goal is to create a complete software stack for NFV ● Includes KVM, libvirt, Open vSwitch, DPDK, OpenDaylight, OpenStack ● Dual goals: ● Technology gaps – write code where needed for NFV ● Upstream first – evangelise NFV to upstream projects, ensure code is accepted ● Members include NEPs, telcos, software & hardware vendors 18 Dave Neary, Red Hat

- 21. What does this have to do with ManageIQ? 21 Dave Neary, Red Hat
- 22. Orchestration is key 22 Dave Neary, Red Hat
- 23. Orchestration in NFV (1) ● VM affinity and anti-affinity ● Putting VMs on the same ovs-dpdk enabled host ● HA VMs on different hosts ● CPU pinning, resource reservation ● Dedicate resources to certain VMs ● Network orchestration ● Monitoring network QoS, reacting to hot spots ● Matching VMs to hardware capability ● VMs needing SR-IOV support 23 Dave Neary, Red Hat
- 24. Orchestration in NFV (2) 24 Dave Neary, Red Hat
- 25. Orchestration in NFV (2) ● VNFs consist of multiple components ● Each with their own performance constraints ● NFV deployment includes multiple VNFs 25 Dave Neary, Red Hat
