Past

! Hardware Defined Services ! Services are Provisioned &

Monitored

Present

! Focus on new service and revenue models

! Trial deployments to verify the business case

Future

! Focus on Software Defined Services for Differentiation

! Real Time Control ! Orchestration & Analytics

Network and Business Transformation

Paralleling the Evolution of Server Virtualization

Where’s the Industry Today, and Headed Tomorrow?


Openness Is Top of Mind Among Operators

SDN/NFV Platform Open interfaces and protocols

Open APIs

OSS Platform

Current Model Must Change!

! Multiple Proprietary Hardware Systems ! Siloes of EMS/NMS ➔ slow inefficient

! Centralized control and orchestration ! Abstract complexity ! Open, programmable and automated


Current OSS Complexity Doesn’t Scale

! Multiple OSS and apps for technology/vendor domains are complex and inefficient

! Multi-Domain Service Orchestration (MDSO) enables convergence

! MDSO simplifies end-to-end service automation and orchestration using web-scale Software, and Open-Source coupled with DevOps tools

Multi-Domain Service Orchestration


Multi-Domain Service Orchestration Business Benefits

Highlights: ! End-to-end service orchestration across multiple

domain controllers ! Service chaining of Virtual and Physical resources

(i.e. VNF and PNF) ! Self-service templates Key Benefits: ! Foundation of an open, software-enabled next

generation OSS architecture !  Lower cost infrastructure ! Offer services to broader range of customers, and

entry to new markets !  Improved service innovation and velocity ! Elimination of vendor lock-in

Sub-rate 100GbE services � need to maximize 100G submarine wavelengths utilization 1

Over-subscription to sell “more” bandwidth over the same existing submarine network 2

Offer on-demand wholesale and/or retail MEF CE 2.0 services @ any rate from 1Mbps to 100Gbps 3

Submarine Packet Switched Network

SDN is extensible across multiple layers, including the packet switching layer carrying data services !


Summary

!  It’s time for the High-Level Programming Language for networks !  Openness is top of mind among network operators !  Internet content players are major proponents ➔ Web-Scale !  Benefits of open SDN greatly outweighs perceived challenges

! Software-defined submarine networks is our future
