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
    • 2VIRTUALIZATION: A (CYNICAL) ENGINEER’S VIEWVIRTUALIZATION IS THE ANSWER BUT WE NEED TO BE MORE THAN BLIND MONKEYS !
    • 3FORCE CONSEQUENCEMassive Capacity ExpansionHigher speed packet & optical transport andbackhaul for small cellsCommoditization of Access Wireless is the new “Wireline”Network & Data Center MergingMove to software-defined and ‘virtualized’networksNetwork BecomingProgrammable PlatformAny web service/enterprise ‘Cloud’ app can fullyleverage the networkTransformation @ web speedNew delivery paradigm and OSS/BSS that adaptsat web scale and speedEvolutionRevolutionINDUSTRY DISRUPTION DRIVEN BY AND AT WEBSCALE & SPEEDWHAT’S THE PROBLEM?FORCES AT PLAY AND CONSEQUENCES
    • 4WHAT’S THE PROBLEM?ANATOMY OF A TELCO APPLICATION (ATCA)System Control & Management Cards Specialized OAM middlewareI/O and load distribution Specialized application middlewareApplication Function A More cards for more capacityApplication Function B More (different) cards for more capacitySpecialized blades with dedicated processors Many different/specialized OS’sSTANDARD COMPONENTS IN SPECIALIZED CONFIGURATION = ‘BOX SCALING RULES’
    • 5• Processors stopped getting fastera decade ago But more transistors per chip =more processor cores But need to create SW thatleverages this parallel scalingWHAT’S THE PROBLEM ?BOX SCALING AND WEBSCALE ARE WORLDS AND DECADES APARTSCALE COMES FROM RUNNING IN PARALLEL
    • 6WHAT’S THE ANSWER: PARALLEL SCALINGApp Speed Up =1(1-P) + P/NAmdahl’s LawP = Parallel Portion of AppN= # ProcessorsVIRTUALIZATION IS THE FASTEST PATH TO WEBSCALE FOR NETAPPSWith Virtualization, P  1Source: Wikipedia

    • 19• NFV will greatly enhance the ability of ‘network applications’ to elastically scale tomeet 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 valueSUMMARY PERSPECTIVEWE ARE LEADING THE WAY TO CREATE THIS NEW VIRTUAL REALITY
