Companies are facing cloud challenges; capacity expansion, commoditization, network and data center merging, network becoming a programmable platform, transformation at web speed. The answer is parallel scaling and the creation of the NFV Industry Group. NFV will greatly enhance the ability of "network applications" to elastically scale to meet changing demand patterns. Alcatel-Lucent is leading the way in this new reality.

  • Network Functions Virtualization: The New Virtual RealityMarcus WeldonCorporate CTO
  • VIRTUALIZATION: A (CYNICAL) ENGINEER’S VIEW VIRTUALIZATION IS THE ANSWER BUT WE NEED TO BE MORE THAN BLIND MONKEYS ! 2
  • WHAT’S THE PROBLEM?FORCES AT PLAY AND CONSEQUENCES FORCE CONSEQUENCE Evolution Higher speed packet & optical transport and Massive Capacity Expansion backhaul for small cells Commoditization of Access Wireless is the new “Wireline” Move to software-defined and ‘virtualized’ Network & Data Center Merging networks Revolution Network Becoming Any web service/enterprise ‘Cloud’ app can fully Programmable Platform leverage the network New delivery paradigm and OSS/BSS that adapts Transformation @ web speed at web scale and speed INDUSTRY DISRUPTION DRIVEN BY AND AT WEBSCALE & SPEED 3
  • WHAT’S THE PROBLEM?ANATOMY OF A TELCO APPLICATION (ATCA) Specialized blades with dedicated processors  Many different/specialized OS’s System Control & Management Cards  Specialized OAM middleware I/O and load distribution  Specialized application middleware Application Function A  More cards for more capacity Application Function B  More (different) cards for more capacity STANDARD COMPONENTS IN SPECIALIZED CONFIGURATION = ‘BOX SCALING RULES’ 4
  • WHAT’S THE PROBLEM ?BOX SCALING AND WEBSCALE ARE WORLDS AND DECADES APART • Processors stopped getting faster a decade ago  But more transistors per chip = more processor cores  But need to create SW that leverages this parallel scaling SCALE COMES FROM RUNNING IN PARALLEL 5
  • WHAT’S THE ANSWER: PARALLEL SCALING Amdahl’s Law 1 App Speed Up = (1-P) + P/N P = Parallel Portion of App N= # Processors With Virtualization, P  1 Source: Wikipedia VIRTUALIZATION IS THE FASTEST PATH TO WEBSCALE FOR NETAPPS 6
  • WHAT IS THE INDUSTRY DOING?NfV Industry Specification Group (ISG)• ~60 Operator-led activity in ETSI• Alcatel-Lucent leadership: only one of two vendors on the NfV Management Team Goals: - Align on architecture and terminology - Identify benefits and assess cost implications - NFV ISG will not create it is own standards, rather: • Specifications that leverage existing industry standards • Provide recommendations to other SDOs INDUSTRY IS VIRTUALLY UNITED 7
  • WHAT IS THE VALUE OF VIRTUALIZATION ? Virtualization Value Factor Qualitative Benefit Quantitative Benefit Greater ability to react to Elastic scaling n/a Gain Factors changing demand Dynamic Control Shorter time to market for new Faster deployment cycles n/a apps/SW releases Domain-specific network Better network re-use and n/a slicing/control OAM/fault isolation Factor Depends on Gain Cost Lower CapEx + OpEx (TCO) n/a Application NEED TO CLEARLY UNDERSTAND THE GOALS TO DEFINE OPTIMAL ANSWER 8
  • VIRTUALIZATION BENEFIT ANALYSISDynamic Control: High Network Media Gateways CPE• Elastic scale Apps• Resource pooling Orchestration Dynamic Control Gain Control Plane Functions Functions• Rapid deployment Network Media Servers Service Creation• Location optimization Analytics Functions Probes Packet Analytics Gateways Platforms Element & Ethernet Network Switches Managers Edge Routers Core Routers Cost (TCO): • NPU vs CPU (CapEx) Low • Technicians (OpEx) Less More Cost Gain VIRTUALIZATION BENEFITS MOST (BUT NOT ALL) NETWORK DOMAINS 9
  • VIRTUALIZATION BENEFIT ANALYSIS: ePC Specialized CapEx OpEx Virtualized $120M $300M $100M $250M $80M $200M $60M $150M $40M $100M $20M $50M $0M $0M Y1 Y2 Y3 Y4 Y5 Operations Energy Maintenance Space Traditional Cloudified Traditional Cloudified Virtualization will typically lead to an ….which must be offset by a decrease increase in CapEx for high in OpEx due to automated DC throughput applications operations (fewer technicians) LOW BW APPS  TCO GAIN; HIGH BW APPS  NO TCO GAIN (BUT DYNAMIC CONTROL GAIN) 10
  • EVOLUTION OF NETWORK FUNCTIONS VIRTUALIZATION AUTO-ONBOARDING ~Today AUTO-SCALINGOperationsEvolution “OPEN” Apps run on GPP + hypervisor, Closed VIRTUALIZATION but on specialized HW for Virtualization carrier grade reliability Apps run on Cloud “CLOSED” Open infrastructure w/elastic scaling VIRTUALIZATION virtualization and Cloud-grade reliability Auto- Automation of on-boarding, Onboarding installation and test Infrastructure Evolution Auto-Scaling Automatic scaling of app functions based on demand WE ARE ALREADY ON THE PATH TO THIS NEW VIRTUAL REALITY 11
  • EVOLUTION OF NETWORK FUNCTIONS VIRTUALIZATIONFROM CLOSED TO OPEN VIRTUALIZATION Closed Virtualization Benefits (Both approaches) Open Virtualization App A Mgt • More capacity per blade System App A App A • More optimal use of HW Middleware VM VM App A Mgt App B Mgt • Able to reallocate HW to varying Standard Proprietary Hypervisor workloads APIs APIs Server Blade Common Cloud App A App B Benefits (Open approach) Management VM VM App B Mgt • Sharing HW across multiple Hypervisor System App B App B applications Middleware VM VM Server Blade • Operations simplification due to Standard APIs Hypervisor common management layer Proprietary APIs Server Blade Risks (Open approach) • New reliability, performance &SLA models • Impact on both NetOps & IT orgs • Failure accountabilities change (NG OSS) WITH EVERY REWARD COMES RISKS THAT NEED TO BE MANAGED 12

  • SUMMARY PERSPECTIVE• NFV will greatly enhance the ability of ‘network applications’ to elastically scale to meet changing demand patterns: - Changing demand by unpredictable usage of operator own applications (above ‘peak’ loads for special events) - Changing demand by unpredictable usage by web applications accessing operator network apps• NFV and SDN also create new value propositions - Slicing to create individual, deterministic, automated and optimized DC and WAN networks - Simplification of CPE but with infinite functionality (and lifetime) - Simplification of operations (provisioning, management, on-boarding) - Flexibility to roll out innovative applications quickly and with low risk (new revenue opportunities)  Value is not always about CapEx or TCO savings• But significant challenges remain to realize full value WE ARE LEADING THE WAY TO CREATE THIS NEW VIRTUAL REALITY 19
