1 SDN-NFV Open Source Landscape, Scaling, Use-Cases Sharon Barkai Cofounder, ConteXtream Santa Clara, CA USA April

2 Agenda SDN-NFV Open Source Landscape and Tiers SDN Open Source Tier for Scalability and Functionality Flow-driving, Flow-handlers, Distribution-federation Extending SDN Open Source to Use-Cases 2

3 Open Source Idea: Community based Heavy Lifting Let s re-invent the wheel once... make it available to all so we can innovate faster 3

4 Key OpenSource Tiers of Functionality Compute Dashboard/API(Horizon) Storage Networking (Neutron) Images/Identity/.. Northbound API ODL-Neutron REST API Open vswitch Nodes 4

5 Orchestration OpenSource Discover physical compute and storage resources Install and manage virtual compute and storage resources Manage networking: Either Physical (VLAN) or as Virtual Compute (vrouter) 5

6 Virtual Switching OpenSource Process OpenFlow and OVSDB commands Apply to the forwarding table entries (addresses & tags) Manage consistency and persistency (space, aging reset) 6

7 OPNFV Leverages OpenSource For Carrier Virtualization 7

8 The Roll of SDN OpenSource - Scaled Dynamics Scaling Dynamic Virtual Connectivity Dealing with Complex Connectivity Logic Overlay, Chaining, Load Balancing, Inter-networking 8

10 Scaling Virtual Connectivity Spines Leaf VM VSwitch The Hop by Hop Flow Provisioning Model too Fragile on Scale, Overlays are now Mainstream 10

11 Scaling Virtual Overlays Action Network Virtualization Overlay Action Action Action A Single Orchestration Event Here Still A Single VM Event may Trigger 1000s of FlowMapping Actions Across Locations (1K subs per VNF) 11

12 Federation of SDN Along Horizontal RFC Lines Control Federated Along Distributed and Interoperable Lines is Scalable-Resilient << RFC >> ^ ODL v Controller Controlled Entity Locations-Subscribers-Services-Instances Controller Controlled Entity ^ ODL v Subs & Apps <> Overlay <> Underlay <> Overlay <> Subs & Apps 12

17 Summary The industry transition to virtualization requires heavy lifting of technology Open Source community is leveraged for this task in three main tiers of functionality work by three main communities SDN Open Source is tasked with scaling virtual connectivity and implementation of overlay RFCs scaling and federating OpenDaylight is done along these RFC lines SDN Open Source is extended to support specific applications using flow-handler plugins and standards based federation schema updates examples in mobile, enterprise, media services 17
