3 Two Open Source Cornerstones for High Reliability Networking OS: SONiC Network Verification: ONE 3

4 Networking OS: SONiC 4

5 A Solution to Unblock Hardware Innovation Monitoring, Management, Deployment Tools, Cutting Edge SDN SONiC SONiC SONiC SONiC Switch Abstraction Interface (SAI) Merchant Silicon

6 Switch Abstraction Interface (SAI) Network Applications Network Applications Hello Simple, consistent, and stable network application stack Switch Abstraction Interface частный 你好 नमस त Bonjour Help consume the underlying complex, heterogeneous hardware easily and faster 6

7 SONiC High-Level Architecture

8 Switch State Service (SWSS) APP DB: persist App objects SAI DB: persist SAI objects Orchestration Agent: translation between apps and SAI objects, resolution of dependency and conflict SyncD: sync SAI objects between software and hardware Key Goal: Evolve components independently 8

9 SONiC Containerization 9

10 SONiC Containerization Components developed in different environments Source code may not be available Enables choices on a percomponent basis 10

14 Network Verification: ONE 14

15 Astronauts use high-fidelity emulators to practice complex, high-risk missions 15

16 Azure engineers use Open Network Emulator (ONE) to practice complex, high-risk network operations Change manager WAN manager Optical link manager Routing protocol coordinator 16

17 Open Network Emulator Fast network with 1000s of devices created in minutes Physical Switch Configuration Software Virtual Machine / Container Configuration Software Seamless push-button deployment Hardware Physical Links vhardware Virtual Links High fidelity devices work exactly as production support from multiple vendors Configuration Software Hardware Production Network Configuration Software Hardware Configuration Software vhardware Configuration Software vhardware Emulated Production Network 17

18 ONE typical usage scenario Network engineer describes desired change SONiC SONiC SONiC SONiC An emulated replica is created SONiC Health verified by Z3 theorem prover Pass/Fail (with feedback, including counterexamples) 18
