12. ONOS Carrier-grade Open Networking Operating System 12
13. What is ONOS? 13 Open Network Operating System (ONOS) is an open source SDN network operating system. Our mission is to enable Service Providers to build real SDN/NFV Solutions. Quarterly Releases, 1.11.0 - released 2017-08
14. Service Provider Networks • WAN core backbone o Multi-Protocol Label Switching (MPLS) with Traffic Engineering (TE) o 200-500 routers, 5-10K ports • Metro Networks o Metro cores for access networks o 10-50K routers, 2-3M ports • Cellular Access Networks o LTE for a metro area o 20-100K devices, 100K-100M ports • Wired access / aggregation o Access network for homes; DSL/Cable o 10-50K devices, 100K-1M ports

17. Key Performance Requirements ONOS Apps Apps Global Network View / State Global Network View / State high throughput | low latency | consistency | high availability High Throughput: ~500K-1M paths setups / second ~3-6M network state ops / second High Volume: ~500GB-1TB of network state data Difficult challenge!
18. Architectural Tenets • High-availability, scalability and performance • Strong abstractions and simplicity to develops apps and solutions • Protocol and device behaviour independence • Separation of concerns and modularity

48. Southbound Architecture • Southbound abstractions, modularity • customization without changing the core • Protocol and device model independency • avoid specifics and dependencies in the core • hidden complexity to upper layers • testability, extensibility and performance ONOS Distributed Core SB Core API NB Core API Apps Protocols and Drivers
49. Southbound overview Southbound protocols in 1.11.0: • OpenFlow until 1.3 + optical extension → 1.5 is in the works. • OVSDB • NETCONF + YANG →Yang tools and Yang management system • SNMP • P4 → thrift api for bmv2 softswitch from barefoot networks. • BGP, ISIS, OSPF → interoperability with legacy network. • PCEP → Path computation element protocol (IETF) • REST and RESTCONF • LISP • TL1 • gRPC

51. Motivation and Goals R&E Network Operators and Users Create a global SDN network Provide L0, L2 and L3 connectivity without “legacy” equipment in the network core Enable network and services innovation ONOS community Demonstrate ONOS in real networks Test High performance, HA and scalability in real networks Learn and improve Requirements/Learning/Bug Fixes ONOS and Use Cases Agile collaboration model R&E Network Operators ONOS Community

55. Have you ever wondered how you can access the Internet?
56. Magic ?
57. Service providers
58. Introduction to Service Provider Network COR D + + R- CORD
59. What does a typical service provider network look like?
60. Telco Central Office (CO) Mobile Residential Enterprise Central Office Can be small or large and has different names in different contexts 60 • CO is a service provider’s gateway to its customers • There are 1000+ of COs • Per CO may support § 10K+ residential subscribers § 10K+ mobile subscribers § 1K+ enterprise customers • CO providers a great vantage point for service providers

67. Challenges • Source of high CAPEX and OPEX • Lack of programmability inhibits innovation • Limits ability to create new services and revenue ØHard to create innovative services 67
68. Knock knock. It’s CORD.
69. What is CORD? 69 Central Office Re-architected as a Datacenter SDN + NFV + Cloud Open Source Software Commodity Hardware (Servers, White-Box Switches, I/O Blades) Large number of COs Evolved over 40-50 years 300+ Types of equipment Huge source of CAPEX/OPEX
70. CORD Aims to Deliver 70 Agility of a cloud provider Software platforms that enable rapid creation of new services Economies of a datacenter Infrastructure built with a few commodity building blocks using open source software and white-box switches
71. Design Philosophy -> Tangible Value 71 SDN NFV Cloud Extends the agility of micro-services to the access network Supports legacy VNFs and pushes the limits of disaggregation Interconnects VNFs and is a source of innovative services XaaS
