    • 1. SDN AND OPENFLOW IMPLICATIONS AND PERSPECTIVES Vinay Bannai SDN Architect, PayPal (eBay Inc. company) Oct 22, 2013
    • 2. SDN DEFINITION  ONF definition  Separation of Control Plane and Forwarding Plane  Logically centralized Control Plane  Abstractions and Programmatic Interface to the Applications  SDN at PayPal  SDN is part of our larger effort to implement SDDC (Software Defined Data Center) and is a critical component  SDDC : Orchestration of compute, storage and network  Part of our new network architecture

    • 4. WHY NEW NETWORK ARCHITECTURE IS NEEDED?  Stranded Compute Capacity  Compute virtualization has been the key driver  Use Compute capacity wherever available irrespective of network zones and boundaries  Multi Tenancy  Different Cloud Clients with varying service and security requirements  Tenant isolation  Rigid Network Topologies  Design networks according to application needs instead of other way around  Automate Everything  Cloud Orchestration
    • 5. USE CASES DRIVING SDN AT PAYPAL  Production  LTS deployment  Flex-up  Flex-down  Multi-tenancy

SERVICE NEEDS OF A TENANT IN A DATA CENTER  Compute and Storage  Network separation/isolation  Overlay networks (VXLAN, NVGRE, STT etc)  Provider networks (VLANs)  Three tier architecture  Logical switches and routers for the VM’s  Perimeter Firewalls and Security Groups  Load Balancers  etc

    • 18. IMPORTANT IMPLICATIONS  Challenges due to organization structure  System Admins (manage compute infrastructure)  Network Admins (manage network infrastructure)  OF enabled Software Switches now reside in a computer server  There are lots of them!!  Networking Device sitting in a device controlled by IT admins  Different approaches to SDN’s  Pure Software play  Pure Hardware play  Hybrid Play

    • 20. SUMMARY • SDN is a component of our SDDC • SDN is mostly pure software, but will move to Hybrid mode • Enables agility, cuts cycle time • OF soft switches reside in the hypervisors • OF soft switches outnumber physical switches 50 to 1 • OF soft switches operate at the edge of the network • Enable multi-tenancy with overlay and physical networks • Enable distributed firewalls and security groups 20 Confidential and Proprietary
