4The Extreme Way: A Networking Success Story We founded Extreme Networks in 1996because networks were slow, expensive and complex –and nobody was doing anything about itWe built some of the largest networks in theworld: Compaq, Microsoft and ShellWe led the silicon switching revolution bymaking networks that are simpler,faster and less expensive.When we started Extreme in 1996, networking had become stuck in a cycle of steadily increasing complexity and cost. The availability of bandwidth, especially Internet bandwidth, had begun to drive a tremendous boom in business applications. This in turn increased the demand for bandwidth, which meant companies had to deploy more and more infrastructure.So far so good -- software companies sell lots of applications, their customers get more productivity from those applications and networking companies sell more networking gear. What could be wrong with that?This could be wrong: the networking gear. Based on CPUs and software, it simply didn’t scale very well. The more of it you bought and implemented, the more complex and expensive the network became. And as millions of new users came online, performance problems became very serious, and very expensive to fix.The founders of Extreme had a better idea. By implementing networking processes in high-speed silicon instead of CPUs and software, they created products that blew away everything else on the market. Extreme’s Layer 3 switching technology enabled the creation of network infrastructure that could truly scale to meet the explosive demand for new business applications. Faster, more easily managed and far more cost-effective, Extreme’s famous purple boxes revolutionized the way people thought about networking.Over the five years of our life as a company, we’ve grown to a half-billion dollars in revenue and nearly 1000 employees. Along the way, we’ve built some of the largest networks in the world, and permanently altered the course of our industry.
5An International Company From Day One Our home is in Silicon Valley, but we are true citizens of the world. From the day we shipped our first product, Extreme has been an international company with an international outlook. We never had to “go international.” We’ve been international from the start.More than 50% of our revenues consistently come from outside the US. We have offices in 25 countries and a presence in 25 more. We’ve developed an extensive support network that provides 24x7x365 customer service and support from technical assistance centers on three continents. No matter where your business operates, or plans to operate in the future, Extreme can support you.More than 50% of revenues come from outside the USOffices in over 25 countries24/7 customer support based on three continents
6Outstanding Financial Performance One of the fastest growing companies inSilicon Valley historyOur focused approach has been a major factor in making us one of the fastest growing companies in Silicon Valley history.*We’ve grown to a half-billion dollars in annual revenues in just five years, a remarkable achievement, and one that hasn’t been duplicated. Over a dozen other networking companies were formed at the same time Extreme was founded, and not one of them has reached the half-billion mark.Our consistent revenue growth is a good indicator of the wide acceptance of both our products and our approach to building networks.*Extreme Networks was named Silicon Valley’s #1 fastest growing company by the San Jose and Silicon Valley Business Journal. The special report, published in the June 30, 2000 issue, ranked Extreme Networks as the leading company for three-year revenue growth.
7Financial Performance: Business Mix Extreme builds both stackable and modular chassis-based products. As you can see in this chart, we currently have a split between the two types of product. Our modular business has grown rapidly in the past two years.In the next chart you can see that Extreme sells its products largely through channel partners.Lastly, as I mentioned before, Extreme has always been an international company. On average just about half of our revenue comes from outside the Americas.

10The Value Of The Extreme Way First, infrastructure built with Extreme products is fast. Silicon-based networking out-performs conventional, CPU-and-software networking every time. We originated this concept, and we continue to lead the industry in every important performance category.The speed of Extreme’s products directly translates into much better applications performance. Applications performance is what defines the value of the network experience, and so is a very important factor in creating effective infrastructure.
11The Value Of The Extreme Way Second, Extreme’s consistent hardware, software and management architectures make networking much less complex. Our core platforms – Summit, BlackDiamond and Alpine – are all based on the same technology. The family resemblance in our product line goes much deeper than the purple boxes: all of our platforms are truly, transparently compatible. This isn’t the case with conventional networking product – they tend to be a rough mix of many different technologies wrapped together with complex software.What does this mean to you? It means that an Extreme infrastructure is easier to configure and deploy, requires very little maintenance and is simple to operate.
12The Value Of The Extreme Way Finally, an Extreme network is a more valuable network, one that delivers better services at a lower cost. Our products are less expensive to acquire and less expensive to operate and support.When you combine performance, simplicity and better return on investment, you get a superior network and a superior applications infrastructure. That’s the Extreme Way.
13The Extreme Product Family NOTE TO SPEAKER: This is the only product slide in the main body of this presentation. In the first revision of this presentation there will be a navigation button which will link to a subset of 5-6 product slides, all very high-level and not deeply technical in nature.Summit
14It’s Going To Be One Big Networked World… More and more, companies are combining their own networking infrastructure with carrier-provided services. Many of Extreme’s customers are doing this today. The emerging Metro Area Network, whether built by a single company or provided by a service provider, or assembled from a combination of private and service provider-owned infrastructure, is supporting a similar set of users and applications.
15The Extreme FutureWe believe Extreme’s Ethernet Everywhere vision is the future of global networkingOur ultimate goal is to be an integral part of the world’s communications systemExtreme is creating a future of easily deployed, highly scalable, intelligently managed, ubiquitous applications infrastructure

23Ethernet Metro Market Drivers Enterprise Networks Outsourcing Data ServicesIT shifting network build-out to Metro providersHigh bandwidth applications (storage, Backup, ..) across the Metro, double traffic every 1~2 yearsExisting Metro technologies (TDM) are NOT data optimizedLegacy networks are built for voiceDifficult to scale to support high bandwidth servicesBetter Economics for delivering high bandwidth servicesDelivering “just in time” bandwidthFaster return on investment
24The Metro Today Data L2/L3 Switches IP Routers ATM Switches SONET ADMs Ethernet AggregationIP RoutersBGP, IP ServicesDataATM SwitchesQoS/TrafficEngineeringTransportFiberSONET ADMsTDM PipesWDMMore BandwidthThe Metro today consists of layers of technologies that satisfy different needs.- The fiber offers the physical connectivity- Wave Division Multiplexing is used to offer more Bandwidth per fiber- Sonnet Add Drop Multiplexers are used to slice the bandwidth into Time Slots using Time Division Multiplexing (TDM). SONET TDM has traditionally been used for voice services and is very inefficient for Data Services since it can only be sold in rigid bandwidth increments (1.5 MBPS to 51 Mpbs to 622 Mbps to 2.4 G and then 10G). ADMs are used to offer point to point transport circuits (T3, OC3, OC12, etc) in the Metro- ATM switches have Traditionally been used for traffic engineering and QoS- IP routers are used for IP services such as Internet connectivity and VPN- and L2/L3 switches are used for Ethernet aggregation.This is very expensive and the upgrade of any of these layers would affect the whole network. The Operational costs for maintaining such networks (operational costs are 80% of the total expenses) are huge.
25The Shortcomings of SONET/SDH SONET is TDM based - optimized for voice not dataComplex and expensive, designed for multi-protocolUses point to point circuits - difficult to provisionMeticulous management of available channelsLong-lead times to enable, change, or upgradeNo granularity - bandwidth comes in big incrementsBurn a whole 45Mbps channel to deliver 10MbpsCan multiplex customers onto full channel but costsRequires ATM and adds more routing complexity

Al large carrier once said, it starts with Ethernet and ends with Ethernet and we pay a Ton of money in between. The new Metro deployments are going to fall under two Models:1- Ethernet IP Switch Routers (note the new terminology here instead of L2/L3 switches) connect directly into the fiber and deliver Ethernet over Glass. In this case the IP switch router has all the IP intelligence and can also offer enhanced bandwidth on the fiber by adding DWDM. This is comparable to the model where Extreme BDs and Alpines with GE or WDM blades connected in a ring. In this case the Extreme switches will offer ring protection (sub-second) via EAPS2- Second model is when Extreme Switches connect into an Optical infrastructure consisting of switches from Nortel (Optera), Ciena (Metro), ONI and Others. In this case, the customer would be putting an emphasis on deploying a big optical infrastructures that handles 60+ wavelength per fiber and would look for Extreme for the IP services portion.

Service Provider’s also need to provide IP address management and other value added IP services such as network filtering and security. Extreme Networks’ Ethernet Everywhere architecture delivers all of these features using a simple Layer 2 simple deployment model that takes minutes, not days, to configure. Extreme’s Ethernet Everywhere approach preserves native Ethernet framing over traditional WAN links, eliminating the arduous and complex task of configuring PVCs, that is typical with solutions based on Frame Relay or ATM in the WAN. Alternatively where other vendor’s aggregation routers are used in the POP, Extreme offers two equally simple configuration options: a switched / routed model and a fully routed model, just like having a traditional full-featured IP router at the edge. The GigaSLAM is the first solution that enables Service Providers to provision wholesale and retail broadband IP services both quickly and cost-effectively.RISER INDEPENDENT HIGH SPEED ACCESSThe GigaSLAM lets Service Providers mix and match Long-range Ethernet over existing CAT 3 and qualified CAT 1 or 2 phone wiring using VDSL technology, with traditional Ethernet over CAT 5 or fiber, all in the same chassis. The IP/Ethernet provisioning model can be applied consistently regardless of the building topology or type of cabling available. This eliminates the complexity of implementing multiple provisioning models depending on the building. With a range of Alpine switch platforms to choose from, a GigaSLAM configuration can scale from 8 to 56 Long-range Ethernet ports (Ethernet over VDSL) and even higher density with a combination of Long-range Ethernet and traditional copper or fiber Ethernet ports.SCALABLE WAN CONNECTIVITY TO THE POINT OF PRESENCEA GigaSLAM configuration can be configured with a flexible array of connections back to a service provider’s point of presence (POP), to provide any desired bandwidth between Mpbs and 45Mbps. The T1 and T3 WAN interface modules support Point-to-Point Protocol (PPP)and Multi-link Point-to-Point Protocol (MLPPP) using either routed IP or switched Ethernet provisioning models over multiple bonded T1 channels. In addition a Gigabit Ethernet module is also available for direct connection to a Gigabit Ethernet metropolitan network. Together, these WAN interfaces provide the most comprehensive range of options in the access network.TRAFFIC ENGINEERING AND PER-SUBSCRIBER PROVISIONINGSophisticated traffic engineering provides the IP Quality of Service control, to satisfy the demands of real-time voice and video applications with enforceable bandwidth and latency guarantees. In addition, service providers can define bi-directional minimum and maximum bandwidths on a per subscriber basis. Service providers can also over-provision the network allowing each subscriber to burst above minimums on an “as-available” basis. Unlike traditional DSLAMs that are no more than access concentrators, the GigaSLAM combines powerful hardware-based packet classification with layer 3 routing and traffic engineering – all made possible by a multi-gigabit switching fabric. This provides the scalability and raw packet forwarding performance to sustain per-subscriber bandwidth slicing from 200K up to 100 Mbps and differentiated service levels for any number of subscribers
