1 Introduction to Quality Assurance for Service Provider Network Functions Virtualization Carsten Rossenhoevel, Managing Director European Advanced Networking Test Center

2 Company Introduction Vendor-neutral test lab based in Berlin Manufacturer Testing and Certification: Performance, Scalability, Availability, Interoperability Proof of Concept testing and Audits for service providers, large enterprises and government organizations Focusing on innovative technologies on layers 2 to 7 Unique, state of the art testing expertise for MPLS, SDN, NFV, 4G/LTE/VoLTE Emulating fully realistic scenarios representative for today s production networks EANTC is 100% independent and vendor-neutral 20-year testing experience matches highest quality assurance standards

3 Industry Differentiation EANTC is the most innovative independent test lab publicly active in NFV Testing We are experienced in testing NFV use case applications and use case-agnostic NFV infrastructure The EANTC team masters latest technologies on par with vendor experts We create independent reports and technical white papers with unique, truly validated content We organize turn-key live showcases, including all the logistics

4 Future NFV Testing Directions Readiness for SP Deployment Legacy Deployment Field Trial Prototype ETSI NFV PoCs Open Source Baseline Testing Time

5 EANTC s Role in the NFV Ecosystem ETSI NFV ISG Active member Defining testing standards for performance and interoperability Open Source Projects Industry Initiatives Private testing Following OPNFV, OpenDaylight, OpenStack Will contribute to OPNFV testing projects Created New IP Agency Test Program with Light Reading Intel Network Builders Partner for Testing Service Provider Proof of Concept Tests Verification of NFV functions, performance, reliability Integration tests/audits for trials and early deployments

6 First Public NFV World Showcase October 2013 EANTC staged the showcase at Layer123 s SDN & OpenFlow World Congress Focus on instantiation & provisioning, portability and elasticity: Virtualized CPE Environment Virtualized BNG Virtualized Middleware (CDNs, Cache Servers, Load Balancers, Application accelerators, firewalls) Virtualized Carrier-Grade Network Address Translation (CG-NAT) Participants in 2013: EANTC is a participating member of ETSI's NFV Industry Specification Group (ISG) which defined the use cases chosen for the demonstration

7 Procera Virtual PacketLogic Software Performance Test Published October 2014 Performance Results Highlights: NFV implementation demonstrates bare metal performance Layer 7 full DPI throughput of 40Gbit/s Average TCP Response Time under 1ms

8 Verifying ETSI NFV Proof of Concept (PoC) #21 October 2014 PoC members showed the benefits of hardware acceleration in NFV environments for functions that are compute or network intensive Participants provided various solutions to the gateway function Tested at EANTC s lab in Berlin Results were published and presented live at the SDN & OpenFlow World Congress 2014 PoC Participants:

9 NFV Industry Schedule (as disclosed) Standards and open source progress swiftly and in parallel Many upstream projects are getting aligned Some vendors in turn base development on OPNFV ETSI NFV Release 2015 OPNFV Brahmaputra Openstack Liberty OpenDaylight Beryllium ETSI NFV ISG Phase 2 Define functional blocks, ref points; focus on interop OPNFV C Release Q4/2015 Q1 Q2 Q3 Q4/2016

10 NFV Projects And Ecosystems Intersect OPNFV ETSI NFV ISG OpenDaylight There are more projects. And I am certainly wrong about the exact overlap. OpenStack

11 NFV Commercial Solution Environment Commercial OSS Solutions ETSI NFV ISG Commercial NFVI Based on Proprietary Solutions Commercial Orchestration Solutions OpenDaylight OPNFV Commercial NFV Infrastructure Based on OPNFV OpenStack

12 Landscape of NFV Testing Each open source project does code/system testing OPNFV has more testing projects beyond ETSI NFV ISG creates testing guidelines IETF Benchmarking WG creates or coordinates performance testing standards as of Sept 8, 2015

13 Most Important OPNFV Testing Projects Functest: Basic OPNFV release testing for functionality Yardstick: Infrastructure verification from the point of view of the VNF Qtip: Performance benchmark suite for OPNFV platform, bottom-up approach (computing / networking / storage) VSPERF: Virtual switch testing framework and test cases Pharos: Distributed lab infrastructure

14 ETSI NFV Testing Projects NFV001: Pre-deployment Testing Methodology NFV002: Interoperability Testing Methodology NFV003: Open source components for NFV (report and awareness creation/human interface) Other ETSI NFV working groups tap into Vswitch performance testing Acceleration hardware implications Public information: Work program Public drafts -

18 Interoperability Reference Architectures ETSI NFV-TST002

19 Interoperability Features ETSI NFV-TST002 Identify topics ( features ) of interoperability Define which functional blocks are involved Summarize all relevant interfaces Next step: Test suite diving into these topics

20 Test Methodologies and Coverage Functionality / Compliance Interoperability VNF Lifecycle Management Performance VNF Package / Software Image Management VNF Fault and Performance Management Network Service Lifecycle Management Network Service Fault and Performance Management Virtualized Resource Management NFVI Networking Management (vswitch) ( ) Infrastructure Resource Management NFV Resilience ( ) NFV Policy Administration NFV Acceleration Management ( )

21 NFV Use Cases Switching/ Routing Elements Mobile Network Nodes Security/ Filtering Policy Management Content Management Broadband Network Gateway Carrier-Grade NAT Provider Edge, CPE Routers Home Routers, Set-top Boxes Packet and Serving Gateways HLR/HSS IMS IPsec Gateways Deep Packet Inspection Firewalls IPv4/ IPv6 IPS/ IDS Virus Scanners/ Spam Filters Video, Voice QoE Session Border Controllers AAA Servers Mobile Policy Mgmt (PCRF) Cache Servers Applicationlayer Load Balancers

22 Don t Forget About NFV Application Testing NFV Service Integration Validate multi-layer independence or interoperability or performance Verify ETSI defined requirements being met NFV Use Case Validation Test multiple virtualized solutions on the same platform(s) across all layers Verify ETSI defined requirements being met Use Case Integration Orchestration NFV Integration Management VNF Hypervisor Host Hardware vepc, vims vgi-lan vcpe vrouter, vbng vfirewall, vcontent Filter
