3 The Extreme Way Delivering the Most Effective Applications Infrastructure

4 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

14 14 Its Going To Be One Big Networked World…

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

16 Broadband Network Trend

17 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 18 Whats 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 19 Other Metro Regions Typical MAN Architecture Level 3 Qwest SONET Public Peering n Gigabit Local ring Sub Gb Local ring Multi-Gigabit Metro Ring On Net Off Net Central Office T1 T3 SONET/SDH core Multi-protocol High reliability Bandwidth guarantees Predictable latency Very expensive Hard to change Voice optimized Inefficient for data

20 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 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 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 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 24 The Metro Today L2/L3 Switches Ethernet Aggregation IP Routers BGP, IP Services Data ATM Switches QoS/Traffic Engineering QoS/Traffic Engineering Transport Fiber SONET ADMs TDM Pipes WDM More Bandwidth

25 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 26 The Metro Is Evolving Ethernet IP Switch Routers WDM/Optical Bypass Ethernet Aggregation, BGP, IP Services, QoS, MPLS, IP TDM More Bandwidth Ethernet Aggregation, BGP, IP Services, QoS, MPLS, IP TDM More Bandwidth Data + Transport SONET Lite/WDM Fiber Packet Pipes, Some Data Handling, More Bandwidth Packet Pipes, Some Data Handling, More Bandwidth Transport + Data

27 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 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

It's a fantastic proposition. The potential market is huge -- Forrester Research

72 72 Key Benefits of Extreme MPLS Provides point-to-point and multipoint VPN capability, improving scalability in Metro networks – and simplifying configuration. Centralized Network Processor based implementation provides MPLS capability on all blades, and the flexibility to implement GRE and other protocols. Traffic Engineering and fast failover capabilities provide a more robust network than possible at Layer 2. Avoids use of Spanning Tree and other Layer 2 loop prevention protocols – which can be difficult to manage in large networks. Support for Jumbo packets
