  2. ALU´s Network evolution vision • Cloud and NFV Foundation: Cloudband • Challenges and Goals • Operating the distrubuted Cloud • CloudbandArchitecture • SDN for DC & Wide Area Networking • Applicability of Nuage VSP further to the Data Center • IP-Optics convergence • IP-Network evolutions towards virtualization CloudBand Management System CloudNode Carrier PaaS

  3. SOFTWARE DEFINED NETWORKING (SDN) TENETS OPENNESS • Programmability with open APIs • Policy-based network abstraction AGILITY • Scalable automation with need-driven service activation and provisioning RESOURCE EFFICIENCY • Dynamic resource control with global network view • Simplified CPE and management

  4. ALCATEL-LUCENT “END-TO-END” SDN ARCHITETCURE PROGRAMMABILITY • Policy-based network abstraction and open APIs • Simplified representation of network to applications by service-layer abstraction of network constructs to hide underlying complexity • WAN • Data Center WEB VELOCITY & SCALE • Demand-driven service activation and provisioning • Customer trigger (packet, flow, VM creation) initiates dynamic network provisioning and service activation as directed by pre-defined policies NETWORK RESOURCE EFFICIENCY • Dynamic resource control with global network view • Extend cloud efficiency model to WAN • Leverage network statistics, multi-layer topology, dynamic virtual network state + control (slicing) to optimize end-to-end service delivery

  5. OUR VISION OF THE FUTURE:EVOLVING HLN TO A PROGRAMMABLE, CONSUMABLE CLOUD NETWORK NETWORK APPLICATIONS Virtualize NETWORK SERVICES CONTROL Software Define IP INFRASTRUCTURE MASSIVE PARADIGM SHIFT FROM CLOSED, STATIC CONFIGURATION TO OPEN, DYNAMIC ADAPTATION

  6. ALCATEL-LUCENT CLOUD IP NETWORK VISION: THE 3 PILLARS IT and Application Services Network Controlling Applications Virtualized Network Functions • Flexible Virtualized Network Functions running on an IT infrastructure (augmented by high performance dedicated functions as appropriate) • End to end automated cloud orchestration, maximizing flexibility and efficiency of applications • SDN, to enable dynamic consumption and programmability of the underlying DC network and transport infrastructure 1 1 • Cloud services & capabilities 2 • Cloud intelligence & control Network Virtualization & Automation(Nuage Networks) Cloud Orchestration & Automation (CloudBand) 2 3 3 • Open, distributed cloud infrastructure SDN • Enterprise DC • MAN/WAN • Network DC • Customers DELIVERING NEW VALUE TRINITY: AUTOMATED, SCALABLE, MULTI-TENANT COMPUTE, STORAGE & NETWORKING

  7. WHERE DOES SDN PLAY?NEW TECHNOLOGIES AUGMENTING EXISTING FUNCTIONALITY Datacenter: Enterprise/Telco Cloud, Service Chaining 1 Dynamic Service Provisioning/VCPE/SD-VPN/MBH 1 2 Local Distribution & Storage 2 Dynamic Traffic Engineering/WAN optimizationMulti-layer optical/IP 3 3 Customer Premesis 2 Core Network Metro / Regional Network 2 3 2 Internet 3 1 Cloud storage & compute 1 Customer Premesis SDN MAKE NETWORK CONSUMABLE: LOWER OPEX/CAPEX, GROW REVENUES Regional Datacenters
