Data Model Driven Management: Architectural Pillars Network Programmability • • • Data accessible via published model driven interfaces or APIs Machine friendly (CLI is not) Enables automation @ scale Visibility & Telemetry • • • Operational Data, Deep analytical hooks Policy-based, flexible, Push Model, more granular, greater scalability Model driven data structures Application Hosting • • • Operators may run their own or 3 rd party off the shelf applications built with Linux tool chains Run custom applications built with Cisco provided SDK Can be run natively co-located with XR control (or) inside an LXC or Docker container Flexible Platform and Packaging • • • Flexible Asynchronous upgrades Modular blocks instead of monolithic delivery Open Bootloaders (i. PXE) and end-to-end auto-provisioning © 2016 Cisco and/or its affiliates. All rights reserved. Cisco Confidential 3

Model Driven Telemetry Operational Data in YANG Data Model format • Push model (streaming) • “As much data as fast as possible” • • In an easily consumable format SNMP can’t compete • Configurable delivery intervals, for example: • • Interface stats @10 seconds BGP stats @60 seconds • Options for serialization/transport • • JSON over TCP GPB over TCP/UDP • Phase 1: Focus on streaming of statistics • Roadmap: Event Based & Pub/Sub © 2016 Cisco and/or its affiliates.

Use Case: VPN Service with SLA Constraints (1/3) Customer requests Multi-Homed VPN service between two (2) sites with Min BW and Disjointness SLAs (e. g. , Contribution Video, Private Line). • NSO: Multi-domain service orchestration, fulfillment and workflow automation. • Example: Data-Model driven provisioning of VPN service with forwarding constraints (e. g. , MIN BW, disjointness SLAs). • ESC: Lifecycle management of VNFs (e. g. , spin up, monitor, scale up/down). • Example: IOS XRv 9000 for v.

Use Case: VPN Service with SLA Constraints (3/3) Customer requests Multi-Homed VPN service between two (2) sites with Min BW and Disjointness SLAs (e. g. , Contribution Video, Private Line). • Model Driven Telemetry: Real-Time Streaming of network operational data. • Example: NCS 5500 telemetry via g. RPC/GPB, TCP/JSON. • WAE: Observes increased latency on path 1 and, in conjunction with SR PCE, optimizes path 1 across the WAN. SR PCEP v. CE-1 VPN Site 1 v. PE-1 v.

Application Engineered Routing • Controller shares data with Host/Agent: Contiv • Topology, labels, extended-community, etc. • Contiv presents an API with a network service menu SR PCE • App chooses “lowest latency” menu selection Controller • Contiv calculates label stack and pushes request to FD. io • FD. io label switches traffic into the network 12 Application Latency data BGP-LS + 10 (pingers) BGP-LS 2 4 1 10 ms 13 {16003, 16005, 24057} 3 11 14 DC (BGP-SR) 6 5 15 ms 7 Dest 8 Low latency wan WAN (IGP-SR) PEER © 2016 Cisco and/or its affiliates.
