Agenda
Solving for the Telco Business Challenge
Making it real Service Fulfillment
Service Design & Creation
Service Assurance and Closed-Loop Control
2
The Telcos Business Challenge
3
Competitive Costs & Function
Expectations Set & Regulations Met
New Function vs. Stable Function
4
Iterative Innovation Refactored Core
New Function vs. Stable Function
5
Iterative Innovation Refactored Core
5x 9s of Resiliency No Jitter/Latency
Scales to 100Gbps Upgradeable
Secure
Solving for it
Agile Methods .. Test First, Test Always Continuous Integration & Deployment Fully automated rigorous testing/monitoring
Cloud Native .. Pets vs. Midget Cattle Simpler, Modular, API Driven, Disposable, Horizontally Scalable
6
Cloud Native
Container strategy driving efficiency, extensibility, and simplicity
Dynamic and Autonomous
Deployment, Configuration & Life Cycle Management
Micro Services..
Simpler Independently Deployable & Disposable Services
7
Policy Driven
8
Policy is hard .. Bigger than any one resource, one infrastructure manager, any one purpose, any one project Policy balances top-down
intent with bottom-up state Intent is refined and delegated
as it gets closer to policy enforcement points
Finally .. Intent is manifest in Coded Rules & Assertions and Monitored States & Configuration
Control plane SDN
Abstract Policies : Intent & Expectation
QoS / SLA Resources Security
Topology changes
Utilization performance
NFV/Cloud Elasticity
Threats DDOS
Calendar
Application Driven
Packet Processing
@
Switching/Routing 5tuple / App aware NFV/High touch
Coded Conditions & Assertions; Monitored State & Configuration
NFV/SDN Business Case for Cloud Based Networking requires Agility with Trustworthy Operations - often opposing requirements

Service Design & Creation Service Fulfilment Service Assurance
BSS
Highly agile interaction between providers of single VNFs and End-to-End network service provider (CSPs)
Much quicker turn-around times compared to classical PNFs Move to continuous delivery of network functions and services
Highly dynamic infrastructure High degree of automation Multiple layers of
infrastructure and technologies
Multi-region
Real-time visibility Observation and correlation of
many data sources Use of analytics Policy-based decisions and

Two Speed IT in Virtualized Networks
22
Virtualization
Orchestration
Heavy Goods Lane Mostly static IT and network Infrastructures and
connectivity Discovery of large environments
Fast Lane Highly dynamic virtualized infrastructure and services Capture of environment changes and metrics
Volume MBs, GBs
Variety Events, EMS bulk imports SNMP/SSH direct discovery MIB/CLI/EMS diversity
Velocity Periodic batches
Volume GBs, TBs (over time)
Variety Events, orchestration systems, distributed packet capture, flow data
Velocity real-time streams
Service Assurance Architecture so far
Siloed disciplines (tools, data, org)
Separation between layers (network, IT, applications)
Built for mostly static infrastructures
