The Extreme Way Delivering the Most Effective Applications Infrastructure

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 revolution by making networks that are simpler, faster and less expensive. We led the silicon switching 4

Broadband Network Trend

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 § 10 G, x. DSL, Wireless and IXCs, ILECs, NAPs, CLECs § Metro fiber and 10 G/WDM removes the bandwidth barrier § Glut will drive prices down, CLECs must reduce costs § IP and Ethernet each eclipsing rivals in Metro Network N A M t e n r e Eth 17

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 18

Typical MAN Architecture Off Net T 1 Central Office T 3 • SONET/SDH core • Multi-protocol • High reliability • Bandwidth guarantees • Predictable latency • Very expensive • Hard to change • Voice optimized • Inefficient for data Other Metro Regions Qwest n Gigabit Local ring On Net Sub Gb Local ring Multi-Gigabit Metro Ring SONET Level 3 Public Peering 19

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 20

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 21

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 22

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 23

The Metro Today L 2/L 3 Switches Data Ethernet Aggregation IP Routers BGP, IP Services ATM Switches Qo. S/Traffic Engineering SONET ADMs TDM Pipes Transport WDM More Bandwidth Fiber 24

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 45 Mbps channel to deliver 10 Mbps § Can multiplex customers onto full channel but costs § Requires ATM and adds more routing complexity 25

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

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 Qo. S 27

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 28

EAPS across Multiple Rings § § EAPS is transparent to the number of rings deployed Each ring has its own EAPS domain(s) § § § An EAPS domain is applied only on a single ring A node can oversee multiple domains on different rings In the figure § § Node P is Master for Ring 2 Node Q is Master for Ring 3 Nodes R and T are both Masters (of different domains) on Ring 0 Node T is also Master of domain on Ring 1 500 VLANs & 40 ms failover 54

Network Login § Admits user to network based on username and password § Prevents pre-authentication DOS attacks 55

Network Login in action • • • Switch detects connection on the switch port Client issues DHCP request, switch responds Switch responds with Login web page Switch performs a request to RADIUS server If user is validated, switch unblocks port and assigns VLAN Network DHCP • DHCP lease timer was set very low initially by Network Login switch. Client will re-request DHCP and because client is on appropriate VLAN, client gets the “real” information 56
