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

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

automation

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
