2 Cisco Confidential2 SDN Hype

3 Cisco Confidential3 Software Defined Networking (SDN) is an approach to building computer networks that separates and abstracts elements of these systems What is SDN? (per Wikipedia definition)

4 Cisco Confidential4 “A platform for developing new control planes” “An open solution for VM mobility in the Data-Center” “An open solution for customized flow forwarding control in and between Data Centers” “A means to do traffic engineering without MPLS” “A solution to build a very large scale layer-2 network” “A way to build my own security/encryption solution” “A way to reduce the CAPEX of my network and leverage commodity switches” “A way to optimize broadcast TV delivery by optimizing cache placement and cache selection” “A means to scale my fixed/mobile gateways and optimize their placement” “A solution to build virtual topologies with optimum multicast forwarding behavior” “A way to optimize link utilization in my network enhanced, application driven routing” “A means to get assured quality of experience for my cloud service offerings” “A way to distribute policy/intent, e.g. for DDoS prevention, in the network” “A way to configure my entire network as a whole rather than individual devices” “A solution to get a global view of the network – topology and state” “Develop solutions at software speeds: I don’t want to work with my network vendor or go through lengthy standardization.”

5 Cisco Confidential5 SDN Flavor 1: Centralized Intelligence

6 Cisco Confidential6 Network Device (router, switch,...) Control Plane (IOS) Data Plane (ASIC)

7 Cisco Confidential7 SDN Controller (software) Programming (ex.: OpenFlow) Applications Examples: Wireless Controllers, Performance Routing (PfR),...

8 Cisco Confidential8

9 9 SDN Flavor 2: Virtual Overlays

10 Cisco Confidential10 IP Network LAX JFK Air Traffic Control Packets Examples: MPLS, IPSec, OTV,...

11 Cisco Confidential11 Virtualized Server Software VM Examples: VXLAN, NVGRE,...

12 Cisco Confidential12 Virtual Network Physical Network Internet / WAN MANAGING TWO NETWORKS......creates complexity

13 Cisco Confidential13 WHY SDN? SIMPLICITY SPEEDPROGRAMMABILITY

14 Cisco Confidential14 A NEW NETWORK MODEL IS CERTAINLY REQUIRED TRADITIONAL NETWORK MODEL TODAY’S SDN DATACENTER MODEL FUTURE OPEN MODEL 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 Software-Based Network Virtualization Application Centric Infrastructure Network of Boxes

15 Cisco Confidential15 Adoption True virtualization and abstraction requires hardware innovation Server Virtualization Network Virtualization Intel/AMD Virtualization Support ACI-Enabled Hardware

16 Cisco Confidential16 ACI BUILDING BLOCKS APPLICATION-CENTRIC INFRASTRUCTURE OPEN STANDARDS OPEN SOURCE NEXUS 9000 SERIES INDUSTRY LEADING ECOSYSTEM

17 Cisco Confidential17 WHAT IS NETWORK CONTROL? A A B B YES You can talk about this: { subject*, L4 Ports, … }  End point A can talk to end point B C C D D NO You can’t  End point C can’t talk to end point D  the rest is path optimization

18 Cisco Confidential18 THE ACI FABRIC Draw a software boundary around collection of switches to make a system Policies  Who can talk to whom  What about  Topology control API Performed by embedded policy enforcement agents (PEs)
