2. Enterprise WAN Strategies Today Andy Gottlieb CEO Talari Networks

3. Next-generation Enterprise WANs a NEW Architecture WAN Virtualization does for WANs what RAID did for storage  lots more bandwidth  hugely lower WAN service cost WAN Virtualization plus other existing technologies enable a revolution in building Enterprise WANs  lower networking OpEx This NEW architecture provides pragmatic, evolutionary path to leveraging Cloud Computing  lower overall IT, applications CapEx, OpEx

4. Mainframe/Minicomputer storage - 1980s First we had Along comes key enabling technology Add layer of hardware and intelligent software… Resulting solution Higher capacity Lower cost Greater reliability RAID Private WANs e.g. Frame Relay, MPLS InternetInternet The Internet! The PC Hard disk WAN Virtualization Storage: Ent. WANs: WAN Virtualization: Doing for WANs what RAID did for Storage

5. 30x to 100x Bandwidth per $40% to 90% WAN Cost Savings More Reliable than Single Vendor FR/MPLS WAN Virtualization Benefits

6. Private WANs too Expensive; The Problem: Public WANs not Reliable Enough $750 - $1500 $450 - $1000 $350 - $600 $175 - $350 $150 - $250 $10 - $15 (ADSL) $ 3 - $15 (Cable) Frame Relay MPLS T1 With QoS T1 ISP Tier 1 T1 ISP Tier 2 SDSL $ / Mbps / Month 99.95% 99.99%? 99.5% - 99.9% 99.x% 99%+ ~99% Reliability SMALL absolute quality differences drive HUGE $/Mbps differences Broadband

7. WAN Virtualization Data Center ISP A ISP B ISP C ISP D INTERNETINTERNET Cable xDSL Frame Relay / MPLS Remote Office T3/OC-3/ GE T1

8. Benefits of Virtualization WAN Physical Network MPLS/InternetMPLS/Internet VPN WAN Virtualization Computing Single CPU Single OS Single CPU Virtual Machines Cloud Computing [Private, Public, Hybrid] Much Lower OpEx Much More Bandwidth Greater Reliability Lower Computing CapEx, OpEx Lower OpEx Somewhat Lower CapEx Still Lower CapEx Lower OpEx Greater Reliability Lower CapEx

9. Server Virtualization Colocation WAN Virtualization WAN Optimization Confluence of Key Technologies will Transform WANs

10. Colocation – now a much bigger Intranet Role Abundant Cheap Bandwidth WAN Virtualization makes Internet reliable enough for Ent. use Great Connectivity InternetInternet

11. Colocation plays a bigger role Downsize or Eliminate Enterprise owned Data Centers InternetInternet

12. Internet  APN Massively more bandwidth at remote and core locations Huge WAN service cost savings Both lowered monthly WAN access bills, as well as massively lower cost/bit Huge WAN service cost savings Both lowered monthly WAN access bills, as well as massively lower cost/bit Far greater reliability, WAN application performance, and application performance predictability Network complexity further centralized Greater network diversity Added reliability, and… leverage with Telecom Service Providers Greater network diversity Added reliability, and… leverage with Telecom Service Providers In This New Paradigm
