  1. Enterprise WAN Strategies Today Andy Gottlieb CEO Talari Networks

  2. Next-generation Enterprise WANsa 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

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

  4. WAN Virtualization Benefits

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

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

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

  8. Confluence of Key Technologies will Transform WANs

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

  10. Colocation plays a bigger role Internet Downsize or Eliminate Enterprise owned Data Centers

  11. In This New Paradigm Network complexity further centralized Massively more bandwidth at remote and core locations Greater network diversity Added reliability, and… leverage with Telecom Service Providers Internet  APN 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

  12. What are the implications of this new architecture? Networking Team

  13. Remote Office (Optional) MPLS nxT1/E1 WAN Optimization WAN Virtualization ISP A xDSL Cable ISP B Local LAN Abundant Downstream Bandwidth Aggregate Upstream Bandwidth Distributed File Services Interactive Applications Real Time Voice and Video

  14. Data Center (Optional) MPLS T3/OC3 WAN Optimization WAN Virtualization ISP C T3/OC3/FE/GE ISP D Lower WAN Access Costs Company Servers

  15. Colo Facility (Optional)MPLS T3/OC3/FE/GE WAN Optimization WAN Virtualization ISP C FE/GE ISP D best performance for server consolidation Company Servers

  16. Compromise Free Internet Backhaul Colo (Optional) MPLS T3/OC3/FE/GE WAN Optimization WAN Virtualization ISP C FE/GE ISP D Do IPS & Firewalling centrally versus the remote office Aggregate bandwidth to/from the remote office increased, and scalable Reliable access to Internet core Company Servers

  17. Result Colo Centralize complexity, policy, in a few locations, without sacrificing performance or security, and do it all at low cost and in a way that will scale (Optional) MPLS T3/OC3/FE/GE WAN Optimization WAN Virtualization ISP C FE/GE ISP D Do IPS & Firewalling centrally versus the remote office Aggregate bandwidth to/from the remote office increased, and scalable Reliable access to Internet core Company Servers

  18. What are the implications of this new architecture? IT/Computing Team

  19. Rethinking Backup, Remote File Access Colo Run DFS Replication - Remote Office files continuously synched to central servers - no need to ever run Backup at remote locations over WAN! (Optional) MPLS T3/OC3/FE/GE WAN Optimization WAN Virtualization ISP C FE/GE ISP D Company Servers

  20. The Path to Cloud Computing Hardware as a Service Storage as a Service EMail SecurityService Email Service Other SaaS (Optional) MPLS T3/OC3/FE/GE WAN Optimization WAN Virtualization ISP C In Building Cross Connect FE/GE ISP D Company Servers
