2. 2 BRAS Firewall DPI CDN Tester/QoE monitor WAN Acceleration Message Router Radio/Fixed Access Network Nodes Carrier Grade NAT PE Router SGSN/GGSN The NFV Concept & Vision Classical Network Model: Hardware Appliances Network Functions are based on specialized hardware One physical node per role. Physical install per site Static. Hard to scale up & out Inefficient: sized for peak loads or cannot handle spikes Session Border Controller standard servers, storage, switches The New Network Model: Virtual Appliances Orchestration & Automation Network Functions are SW-based Multiple roles over same HW. Remote operation Dynamic. Extremely easy to scale Scalable number of VMs EPC

3. 3 Fields of Application •Mobile networks:  HLR/HSS, MME, SGSN, GGSN/PDN- GW, eNodeB, vEPC •NGN signalling: SBCs, IMS •Switching elements: BNG, CG-NAT, routers •Home environment: home router, set top box, picocell •Application-level optimization: CDNs, Cache Servers, Load Balancers, Application Accelerators •Security functions Firewalls, virus scanners, intrusion detection systems, spam protection •Tunnelling gateway elements: IPSec/SSL VPN gateways •Converged and network- wide functions: AAA servers, policy control and charging platforms •Traffic analysis/forensics: DPI, QoE measurement •Traffic Monitoring: Service Assurance, SLA monitoring, Test and Diagnostics

4. 4 EVA principle: elasticity, velocity, agility + scaleability ‒Flexibility to easily, rapidly, dynamically provision and instantiate new services in various locations (i.e. no need for new equipment install) ‒Increased speed of time-to-market by minimising the typical network operator cycle of innovation. More service differentiation & customization. Great for BC/DR. ‒Improved operational efficiency by taking advantage of a more homogeneous (physical) network platform Reduced equipment costs through equipment consolidation, leveraging the economies of scale. Eco-friendly. Reduced operational costs: reduced power, reduced space, improved network monitoring Software-oriented innovation (including Open Source) to rapidly prototype and test new services IT-oriented skillset and talent (readily available in global geography, flexible). Convergence of IT & NetOps. NFV: a Value Proposition

10. www.etsi.org/nfv-poc ETSI NFV PoC Zone @ SDN & OpenFlow World Congress (Oct. ‘14) NFV POCs and ARM Two PoCs that ARM participates in: •POC#19: Service Acceleration on NW Functions in Carrier Networks ‒Showcase an orchestrator that is able to setup multiple functions to be offloaded from the network element avoiding any back and forth traffic delays between the network element and the external COTS servers either before or after completing each network function. ‒ARM, Avago Technologies, Ericsson, Tieto, Procera, AT&T, ‒Accepted. Start date: June 1, 2014 •Demonstration of vEPC Applications on AMD 64bit ARM and x86 platforms and Enhanced Resource Management ‒ARM, AMD, Aricent, Vodafone ‒Submitted.

11. POC#19 Proposed PoC •PoC Goal #1: verify Acceleration of Virtualized NW functions (VNFs) that work on carrier networks utilizing commoditized white box hardware. •PoC Goal #2: demonstrate VNF disaggregation from a given network element. •PoC Project Goal #3: demonstrate performance difference when VNFs get disaggregated onto COTS servers vs when the COTS servers get augmented with network function acceleration SoCs. Axxia is a specific ARM- based SoC from Avago Technologies (LSI) intended to be used for this POC

12. Creates competitive supply of innovative applications by third parties Strategic Networking Paradigms •NFV and SDN are highly complementary, they are mutually beneficial but not dependent on each other. •Software is common denominator Creates abstractions to enable faster innovation Software Defined Networking Leads to agility, Reduces CAPEX, OPEX, Network Functions Virtualisation Open Innovation

13. 13 What should be open? ‒Open Source (software) ‒Open Design (hardware) ‒Open Standards ‒Open Interfaces, APIs (plugins) ‒Open SDKs Open Community (not controlled by single vendor) Decoupling of software and hardware. Programmable network functions Benefits ‒modularization: best of breed, flexibility ‒customization (mix & match) ‒reduced costs ‒easy to upgrade, no vendor lock-in Open Networking & NFV Network Operating System Application / Tools / Services Hardware (switch/server)) Virtual Switch API API API API

14. 14 Issues: ‒(harmonious) integration and consistency ‒for operators: carrier-grade (HA & five 9s, DR/BC, SLAs, reliability) ‒security, testing & interoperability, certification, licensing, regulation Creating a sandbox of open source tools would be ideal Open VNFs ‒Open-sourced firewalls, load balancers, DPI Emergence of virtual switches and routers as vital block elements Disaggregation of switch hardware/software supports ‒dynamic/programmable QoS (selective per application/user/virtual network, etc) ‒monitoring/analytics tools ‒run many NOS on same system (group of physical/virtual ports)

15. 15 SDN can play a key role in the orchestration of the infrastructure (physical, virtual) ‒Provisioning and configuration of VNFs ‒Allocate and manage resources (e.g., bandwidth) ‒VM mobility ‒Automation & programmability ‒Security & policy control ‒Centralized network control. Unified control & management plane? Service composition (NFV Forwarding Graphs) ‒Directing traffic flows to VNFs ‒Traffic flow characterization very important (especially for mobile, E2E scenarios) NFV+SDN

16. 16 NFV creates a very dynamic environment ‒SDN can present an overall logical view, map ‒SDN’s programmability is key aspect (i.e., for automation) Ad-hoc, on-demand, secure virtual tenant networks Extend M&O to include Network Management SDN could enable and accelerate the virtualization of the network and the “cloudification” of the carrier (COs/PoPs become DCs) Challenges in “dovetailing” SDN with NFV ‒Hybrid virtualized/non virtualized environment ‒Mixed SDN/non-SDN (legacy) network elements/domains ‒SDN across NFV boundaries ‒NFV across SDN boundaries (this may require some sort of SDN federation) NFV and SDN together can create greatest value

21. 21 APIs: important for plug-n-play, especially for open platforms Google, FB, Microsoft, eg. WebRTC They can enable plethora of innovative (eg, ad-hoc/customized) services and lead to new business models for the telcos ‒Monetization opportunities (eg., consumers, enterprise, VNOs, etc) SPs: From function/service-based to app-based models ‒Deploy resources (including VNFs on-demand) as an app/user needs them ‒Example: different mobile apps may require different connectivity mode (4G, WiFi, multiple WiFis, etc) ‒Example: customer-tailored, brokerage-based services (eg., VoIP calls) ‒Managed services (the evolution of VPNs) Integrate (network and business) intelligence: write your own VNF! The Role of APIs Smart mobile devices and IoT will precipitate the adoption of APIs for telco Apps
