3 What Is Network Functions Virtualization (NFV)? What if you could have this in your network today? NFV enables users to realize the benefits of the cloud by replacing closed appliances with their choice of software that can be hosted anywhere in the network on their choice of open hardware ADVA Optical Networking.

4 What is Software-defined WAN (SD-WAN)? Software Defined WAN HQ IP-VPN (MPLS) Service Provider Data Center Branch Branch Public Internet Connector GW Off-Net Branch Business Drivers Enterprises seek to reduce costs and increase network connectivity flexibility Service Providers offer variety of managed networking options giving enterprises choice Benefits Access flexibility and redundancy for enterprises Networking solution with policy-based path control to optimize traffic across multiple WANs Extend CSP reach to off-net customers For more information, please see: SD-WAN 2.0: Evolving to a Complete Solution 2017 ADVA Optical Networking.

5 Q: Why is SD-WAN Hot? A: Money! As we saw when covering why the NEW architecture will happen MPLS is typically priced at $300 - $600 per Mbps per month for the copper connectivity typically deployed at all but the very largest enterprise locations, while the monthly price of broadband connectivity is now $ $15 per Mbps per month.

6 Service Provider Wins for SD-WAN Suppliers SD-WAN Supplier These are all appliance-based (except for Verizon, Orange and Masergy). Each operator wants to move to an open solution based on NFV. Cisco IWAN Cisco Viptela Nuage Silver Peak Riverbed TELoIP VeloCloud Versa Announced Service Provider Wins Telstra, Vodafone, BT Verizon, NTTPC, Singtel, PCTL BT, NTT Data Intellilink, Exponential-e, China Mobile, Telia Sonera, Telefonica, MyRepublic, Telus Masergy, China Telecom, NTT, Interroute Orange, Verizon Access One, X10 Networks, California Telecom, Freewire AT&T, Windstream, TPx (FKA TelePacific), MegaPath, Global Capacity, Sprint, GTT, MetTel, Telstra, Macquarie Telecom, CHT Global, Vonage CenturyLink, Tata, Comcast, Colt, RCN, S-Net, Verizon, China Telecom Global 2017 ADVA Optical Networking.

7 What s Wrong With Hardware Appliances? They work, BUT Closed, single-function, single-supplier, standalone, etc. OLD FASHIONED! 2017 ADVA Optical Networking. All rights reserved. 7

8 NFV is About REPLACING Appliances Movement to open, flexible white-box CPE model via NFV = Universal CPE 2017 ADVA Optical Networking. All rights reserved. 8

9 More on Universal CPE (ucpe) ucpe gives enterprises and operators a way to do things they couldn t do before: Consolidate multiple appliances into one open and generic server Have a choice in hardware from a range of suppliers, scaling up and down Have a choice in software multiple functions from multiple suppliers Change the service without changing the hardware Solve import/export problems 2017 ADVA Optical Networking.
