The Extreme Way

Delivering the Most Effective

Applications Infrastructure

the extreme way a networking success story
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.

the extreme future
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

broadband network trends
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

what s a metro area network man
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

who are the metro players
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
metro provider business strategy
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
metro provider network strategy
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
ethernet metro market drivers
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

The Metro Today
the shortcomings of sonet sdh
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

ip ethernet technical advantage
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

ip ethernet business advantage
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

eaps across multiple rings
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

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

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

    • Two ports but two applications on the same VLAN
      • Get dedicated b/w via Policy based QoS
  • VoIP: Slowly but surely
    • Uses protocols like H.323 and/or SIP (Session Initiation Protocol)
    • Once again need L3/L4 packet classification capability for toll quality experience

key benefits of extreme mpls
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
