An SME perspective on SDN & NFV promises: programmability, abstraction and new business roles Nicola Ciulli Head of Research & Development, Nextworks Future Internet Assembly 2014, High Profile Plenary Session www.nextworks.it Let’s start from the conclusions [Q1] What is in NFV and SDN for SMEs? The promise of a new, unlocked business ecosystem where SMEs can be the new Network App developers and maintainers [Q2] What is the benefit for an SME to be active in NFV & SDN standardization? SDN & NFV open / standard interfaces are still a growing jungle, and are key for SMEs to develop business ideas and products [Q3] How can research help? SDN & NFV are broad and wild field; research is key to pioneer in the SDN farwest and validate intuitions before standards can regulate it [Q4] How can large scale test-beds, as made available by NRENs, help? In reality, networks are never small and simple. Large scale virtual laboratories are key to properly validate and showcase SDN/NFV product ideas Future Internet Assembly 2014, High Profile Plenary Session March 18th 2014, Athens 2 The promises behind SDN and NFV 2 key promises for network operators… “Extreme” service orchestration and deep programmability, i.e. beyond the black-box configuration • New, operator-defined, service features and compositions • Full control of the network boxes Ability to deal with heterogeneous network technologies in an (mostly) agnostic way • Towards a more open market of network gears • Shorter time to market for new services and network technologies … and 1 major promise for the (potential) stakeholders in the network equipment and software business Can create new roles and business threads in network software development Future Internet Assembly 2014, High Profile Plenary Session March 18th 2014, Athens 3 The technology jungle in networks network operator service provider datacenter provider … In legacy networks, each technology and architecture requires its own control & management to install, configure, and operate it CLI BGP ? AAA VPNs IS-IS V MPLS OSS SNMP ? RSVP virtualization OSPF-TE OpenFlow Carrier-grade Netconf Ethernet Future Internet Assembly 2014, High Profile Plenary Session GMPLS March 18th 2014, Athens 4 SDN can help, with a long term vision 1. Open/standard southbound interfaces • OpenFlow, XMPP, SNMP, CLI, Netconf, I2RS, PCEP, etc. 2. A driver for each class of (subnetwork of) nodes • To abstract the hardware (and software!) internals and make it “plug and play” 3. The concept of Network Operating System • To abstract the heterogeneity underneath • To generalize the procedures required for configuring / managing / controlling the network functions in a set of primitive OS functions • i.e. we shouldn’t have to buy a new management system with a dedicated software when we deploy a new network technology 4. A powerful northbound interface for lots of user-friendly applications • Full-featured access point for the network control, e.g. for innovative NMS tasks, new virtualized network services, etc. • This is where the SDN “programmability” promise kicks in Future Internet Assembly 2014, High Profile Plenary Session March 18th 2014, Athens 5 The concept of Network Operating System App App App App App App App Northbound API Network Operating System kernel (SDN Controller with abstraction layer) Southbound API drv drv drv drv drv drv drv drv drv drv drv drv drv drv drv drv drv drv drv Future Internet Assembly 2014, High Profile Plenary Session March 18th 2014, Athens 6 Towards a SDN/NFV business ecosystem SDN and NFV are not about reinventing network management / control and data plane software It is more about leveraging on open interfaces, common network control frameworks (SDN controller), functions virtualization to build new network services and service models This can really open to new business roles in the network software development market, esp. for SMEs Network hardware (i.e. fabric) manufacturer NOS kernel developer Driver developer App developer Software integrator System (sw + hw) integrator Future Internet Assembly 2014, High Profile Plenary Session March 18th 2014, Athens 7 A new value-chain from SDN From a Vertical value-chain To a more Horizontal value-chain App App App NOS NOS NOS NOS drv drv drv drv drv drv drv drv drv drv drv Future Internet Assembly 2014, High Profile Plenary Session App App March 18th 2014, Athens App 8 [Q1] What is in NFV and SDN for SMEs? SDN offer today can be anything vendors just have Sometimes an API to equipment Sometimes a series of scripts or macros in the operating system that automagically execute commands (via YANG, NETCONF) But, SDN & NFV ultimate promise is more about Automation, i.e. intelligence, not scripts nor dumb APIs Programmability, i.e. no CLI, rather REST API Open interfaces, i.e. different possible views to different user profiles Open source, i.e. move the value on the Apps & customization more than the OS internals This “SDNv2.0” adheres more to the initial concept and can really open to new business roles for SMEs Softwarized network functions on top of whiter and whiter network boxes User-/Operator-driven network functions using open network interfaces Future Internet Assembly 2014, High Profile Plenary Session March 18th 2014, Athens 9 [Q2] What is the benefit for an SME to be active in NFV and SDN standardization? SDN & NFV have their hype today, but consolidated specifications are still to come ([open] interfaces, detailed architecture, etc.) Standards here are still a intricate jungle… difficult to predict where things will converge It’s not as easy as in the past… sitting down and waiting for the architecture and protocols specs to be released, and to understand which of the standards is the “right one to master and to implement” E.g. ATM, PNNI, MPLS, GMPLS We need to stand closer to the window, and watch things evolve, reach consensus or just disappear in disagreement. Have ideas and predictions on what “SDN item” we should learn, get familiar with, implement Use-cases and propositions related to innovative ideas and products are well received in NFV & SDN SDOs SMEs can be promoters of such ideas in these SDOs and also be among the early adopters/implementers of them Still, a benefit is also in sitting together with big Telcos (operators, ISPs), helping them to shape up their visions on SDN (more open field that in the past) and create business opportunities from this Future Internet Assembly 2014, High Profile Plenary Session March 18th 2014, Athens 10 [Q3] How can research help? SDN is evolving very fast, much faster than other architectures and protocols in the past But it’s a far west of architectures and protocols… approximately anything can be defined as SDN & most of legacy network control could fit in SDN Still very light and not-normative standards Research is mostly about bright ideas and how to let the right software piece fit in the right place in the right overall picture Therefore, research is key to validate SDN/NFV intuitions before any SDO can regulate it Future Internet Assembly 2014, High Profile Plenary Session March 18th 2014, Athens 11 [Q4] How can large scale test-beds, as made available by NRENs, help? Networks are never small and simple… and validation in large scale virtual laboratories is key to consolidate SDN/NFV product ideas before engineering them into products R&E networks as well as FIRE infrastructures have always pioneered new network technologies in the large-scale/continental networks Because of the large capacity of the R&E infrastructures Because of the less compelling need to capitalize on it and bill large user pools SDN & NFV are perfect new technologies for trials They build upon the softwarization and virtualization of network functions, i.e. it is an easy task to clone and replicate on large-scale test-beds SDN & NFV put more control power in the hands of the network operator Yet, it would be crucial to build these large scale test-beds beyond the R&E networks R&E and Telco virtual labs can be used to validate SDN/NFV even larger, and with all the involved stakeholders The impact and sustainability of any showcases can be unprecedented Future Internet Assembly 2014, High Profile Plenary Session March 18th 2014, Athens 12 But still many questions behind the corner… Are there enough margins for all the stakeholders along the value chain? Once the value chain is defined, what is the chain of responsibilities and reasonable SLAs in it? E.g. 1st, 2nd and 3rd line of support: who provides what? E.g. who’s liable when something goes wrong? Is there a risk that the whole thing is much more complex for Telcos? What is actually missing to package turnkey solutions? Why should a dominant vendor go SDN? Could it be that the whole value chain is mimicked internally, e.g. with spin-in companies? Programmability: why should I be fancy of doing with SDN something that I could have done with predecessor architectures, and didn’t care to do? e.g. bandwidth-on-demand, network optimization, etc. app developer Future Internet Assembly 2014, High Profile Plenary Session network operator system integrator software integrator hardware manufacturer NOS developer driver developer March 18th 2014, Athens 13 Thank you!
