  4. The Extreme Way: A Networking Success Story We founded Extreme Networks in 1996 because networks were slow, expensive and complex – and nobody was doing anything about it We built some of the largest networks in the world: Compaq, Microsoft and Shell We led the silicon switching revolution by making networks that are simpler, faster and less expensive.

  5. An International Company From Day One More than 50% of revenues come from outside the US Offices in over 25 countries 24/7 customer support based on three continents

  15. The Extreme Future We believe Extreme’s Ethernet Everywhere vision is the future of global networking Our ultimate goal is to be an integral part of the world’s communications system Extreme is creating a future of easily deployed, highly scalable, intelligently managed, ubiquitous applications infrastructure

  16. Broadband Network Trend

  17. Broadband Network Trends • 80% of traffic is data and doubling every 12 months • Broadband networks must evolve from voice to data optimized • Demand for more speed, lower price, better service • Plenty of alternatives technologies and players • 10G, xDSL, Wireless and IXCs, ILECs, NAPs, CLECs • Metro fiber and 10G/WDM removes the bandwidth barrier • Glut will drive prices down, CLECs must reduce costs • IP and Ethernet each eclipsing rivals in Metro Network Ethernet MAN

  18. What’s a Metro Area Network (MAN) • High-capacity fiber backbone covering metro area • Typically runs on SONET ring or dual ring • Usually multiple interconnected rings • Utilizes fiber owned or leased by Service Provider • Cost breakdown different from long haul networks • Long haul: 70% fiber, 30% equipment • Metro area: 30% fiber, 70% equipment * • Backbone equipment is very strategic investment for Metro Area Network service providers * Source: Banc Robertson Stevens 1999

  19. Central Office • SONET/SDH core • Multi-protocol • High reliability • Bandwidth guarantees • Predictable latency • Very expensive • Hard to change • Voice optimized • Inefficient for data T1 T3 Level 3 n Gigabit Local ring PublicPeering Sub Gb Local ring Typical MAN Architecture Other MetroRegions Off Net Qwest Multi-Gigabit Metro Ring SONET On Net

  20. Who Are The Metro Players • Metro Service Providers • Typically Regional CLECs (Tier 2) and ILECs • Sell retail bandwidth and services to Enterprises • Sell wholesale bandwidth and services to CLECs and ISPs • IXCs, NAPs, Next Generation Carriers • Offering wholesale long haul transport between regions • Municipalities, Utilities • Offering wholesale dark fiber leasing to CLECs and ILECs

  21. Metro Provider Business Strategy • Metro bandwidth at unprecedented price points • Disruptive price point for high-bandwidth customers • Faster deployment and flexible control of bandwidth • Within same metro and long distance between metros • Large / medium Enterprises and Tier 3 CLEC/ISPs • Inter-connecting enterprise LANs and SP POPs • Providing wholesales and retail Internet access

  22. Metro Provider Network Strategy • IP centric network and product strategy • IP/Ethernet hand-off to customers • Via switch at customer premises or co-lo facility • Own as much of the backbone as possible • Purchase or long term lease of metro dark fiber • Own backbone equipment, customer located equipment (CLE) • Lease wholesale bandwidth for long haul

  23. Ethernet Metro Market Drivers • Enterprise Networks Outsourcing Data Services • IT shifting network build-out to Metro providers • High bandwidth applications (storage, Backup, ..) across the Metro, double traffic every 1~2 years • Existing Metro technologies (TDM) are NOT data optimized • Legacy networks are built for voice • Difficult to scale to support high bandwidth services • Better Economics for delivering high bandwidth services • Delivering “just in time” bandwidth • Faster return on investment

  24. L2/L3 Switches Ethernet Aggregation BGP, IP Services IP Routers Data QoS/Traffic Engineering ATM Switches TDM Pipes SONET ADMs Transport More Bandwidth WDM Fiber The Metro Today

  25. The Shortcomings of SONET/SDH • SONET is TDM based - optimized for voice not data • Complex and expensive, designed for multi-protocol • Uses point to point circuits - difficult to provision • Meticulous management of available channels • Long-lead times to enable, change, or upgrade • No granularity - bandwidth comes in big increments • Burn a whole 45Mbps channel to deliver 10Mbps • Can multiplex customers onto full channel but costs • Requires ATM and adds more routing complexity

  26. Ethernet Aggregation, BGP, IP Services, QoS, MPLS, IP TDM More Bandwidth Data + Transport SONET Lite/WDM Packet Pipes, Some Data Handling, More Bandwidth Transport + Data Ethernet IP Switch Routers WDM/Optical Bypass Fiber The Metro Is Evolving

  27. IP/Ethernet Technical Advantage • Ethernet now extends from MAN to building • Over any MAN/WAN and in-building media (fiber, copper, air) • Ethernet or IP from Gigabit MAN to customer point • No longer necessary to have a multi-protocol backbone • IP/Ethernet service model is easy to configure • VLANs enable point and multi-point connections • Ideal for interconnecting COs, POPs, branch offices (TLS) • IP routing enables efficient Internet traffic hand-off • Ideal for VPNs, content distribution, hosting services Bandwidth by the slice and policy-based QoS

  28. IP/Ethernet Business Advantage • IP / Ethernet economics means faster profitability • 80-90% saving over SONET total cost of ownership * • IP / Ethernet gives Carrier the competitive edge • Better pricing and faster deployment • More responsive with less expertise • Simpler for you and customer to manage • Allows rapid, cost-effective service provisioning * Sources: Dataquest 12/99, Yankee 12./00

  33. Disruptive Pricing Example • Double the bandwidth, half the price • Traditional Telco price structure • T1 1.5 Mbps ~ $1,000/month • T3 45 Mbps ~ $10,000/month • Optical Ethernet price structure • 3 Mbps ~ $900/month • 100Mbps ~ $4,000/month SONET/ATM $ IP/Ethernet Megabits “Customers can buy as little or as much bandwidth as they want. It's a fantastic proposition. The potential market is huge” -- Forrester Research

  34. Market Size for GbE MAN • GbE is a new, price-disruptive technology • With enhanced Carrier-grade features (APS, QoS, Billing), GbE can have a huge upside in the market! Total Market: $25.7B Source: U.S. Bancorp Piper Jaffray and RHK, Inc.

  35. Retail Services Large/Medium Enterprises Transparent LAN services (TLS) ATM/FR/IP managed services High speed Internet access Voice trunks between offices Communities of interest (Extranet) Differentiated IP Services Ethernet MAN Market Segments Wholesale Services Regional ISPs, Tier 3 CLECs • Trunks between COs and POPs • POP/Data Center co-location • Aggregation of MTUs for BLECs • Content distribution services • Upstream Internet access • Region to region Interconnect Revenue split between Retail and Wholesale varies, depending on Metro provider’s main business focus
