  1. Application Centric Infrastructure Gustavo Santana CCIE# 8806 (DC,SAN,R&Sw) Data Center TSA

  2. SDN Hype

  3. What is SDN? (per Wikipedia definition) Software Defined Networking (SDN)is an approach to building computer networks that separates and abstracts elements of these systems

  4. “A way to optimize link utilization in my network enhanced, application driven routing” “An open solution for customized flow forwarding control in and between Data Centers” “An open solution for VM mobility in the Data-Center” “A platform for developing new control planes” “Develop solutions at software speeds: I don’t want to work with my network vendor or go through lengthy standardization.” “A way to reduce theCAPEX of my networkand leverage commodityswitches” “A means to get assuredquality of experience formy cloud service offerings” “A solution to build a very large scale layer-2 network” “A means to do traffic engineering without MPLS” Diverse Drivers Common Concepts “A solution to build virtual topologies with optimum multicast forwarding behavior” Different Execution Paths “A way to optimize broadcast TV delivery by optimizing cache placement andcache selection” “A way to build my own security/encryption solution” “A means to scale my fixed/mobile gateways and optimize their placement” “A solution to get a global view of the network – topology and state” “A way to configure my entire network as a whole rather than individual devices” “A way to distribute policy/intent, e.g. for DDoS prevention, in the network”

  5. SDN Flavor 1: Centralized Intelligence

  6. Control Plane (IOS) Network Device (router, switch, ...) Data Plane (ASIC)

  7. Applications SDN Controller (software) Programming (ex.: OpenFlow) Examples: Wireless Controllers, Performance Routing (PfR), ...

  8. SDN Flavor 2: Virtual Overlays

  9. LAX JFK Air Traffic Control Packets IP Network Examples: MPLS, IPSec, OTV, ...

  10. VM VM VM VM Software Software VM VM Virtualized Server Virtualized Server Virtualized Server Software Examples: VXLAN, NVGRE, ... VM VM VM

  11. Managing two networks... Virtual Network Internet / WAN Physical Network ...creates complexity

  12. WHY SDN? PROGRAMMABILITY SPEED SIMPLICITY

  13. A New network Model is certainly Required TRADITIONALNETWORK MODEL TODAY’S SDN DATACENTER MODEL FUTURE OPEN MODEL Network of Boxes Software-BasedNetwork Virtualization Application CentricInfrastructure Needs Agility and Time to Applications Lacks Scale, Visibility, Security More Complexity Disjointed Overlay and Underlay Open Source, Open APIs Physical and Virtual Policy and Automation

  14. Why innovate in hardware too? Server Virtualization Intel/AMD Virtualization Support Adoption Network Virtualization ACI-Enabled Hardware True virtualization and abstraction requires hardware innovation

  15. Aci Building Blocks • APPLICATION-CENTRIC Infrastructure APIC • NEXUS 9000 SERIES • Industry LeadingECOSYSTEM • Application Policy Infrastructure Controller OPEN STANDARDS OPEN SOURCE

  16. What is Network Control?  the rest is path optimization YES You can talk about this: { subject*, L4 Ports, … } NO You can’t C D A B  End point C can’t talk to end point D  End point A can talk to end point B

  17. The ACI Fabric API • Policies • Who can talk to whom • What about • Topology control Performed by embedded policy enforcement agents (PEs) Draw a software boundary around collection of switches to make a system

  18. Multi-Hypervisor-Ready Fabric Network Admin APIC Application Admin ACI Fabric VLAN VXLAN VLAN NVGRE VLAN VXLAN VLAN ESX Hyper-V KVM PHYSICAL SERVER Hypervisor Management

  19. SPOTLIGHT ON THREE GAME-CHANGING DIFFERENTIATORS 1 2 3 APPLICATION-CENTRIC POLICY MODEL PHYSICAL + VIRTUAL OPEN AND SECURE • Operationally Simple • Lowest TCO • Zero-touch provisioning • Health Metrics • Visibility / Telemetry • Troubleshooting • Open APIs / Open Source • Advanced Security • 3rd Party Integration
