  1. The Impact on the Internet Economy from Gigabit Ethernet and BeyondAPRICOT 2001 Randall AtkinsonSenior Scientist, Extreme Networks

  2. Easy Access to Information Applications Multiple Information Sources E-Commerce Networked Storage Web Publishing Streaming Video/Audio Intranets Voice Over IP Unpredictable Traffic Global Internet is Changing Everything!!! Ethernet/Fast Ethernet Desktop Segment ATM FDDI MAN Data Center Core Routers or Switches Internet

  3. Performance, Control, and Scalability LAN, MAN, WAN support, Ethernet, POS, WDM, VDSL... Integrated Server Load Balancing, Security, etc. Bandwidth Allocation and Management - QoS Layer 3 Switching - L4-7 QoS Traffic Classification & Prioritization - QoS Non-Blocking Architecture Wire-Speed Switching & Routing Layer 3 Switching Network Infrastructure Requirements

  4. 2001/2002 WAN Level WAN Access Services Wide Area Core Connectivity Wide Area TDM Connection 1999/2000 MAN Level MetroNetwork MetroNetwork 1997/1999 Backbone Switch Enterprise Router Backbone Level 1970’s/1996s Workgroup Switch Workgroup Level Desktop Switch Servers Desktop Level The Increasing Role of Ethernet 10,000 Mbps 10 GigabitEthernet 1000 Mbps GigabitEthernet 1000 Mbps GigabitEthernet 10/100 Mbps Ethernet

  5. 1999 2000 2001 2002 802.3ae Started 1st Draft 4th Draft HSSG 2nd Draft 3rd Draft Sponsor Ballot Standard Approval Working Group Ballot IEEE 802.3ae 10 Gigabit Ethernet • Motivation: • Leverage success and scalability of Ethernet • Opportunity to converge Ethernet with Optical Networking

  6. 802.3ae 10GE Objectives -- Compatibility • Objectives for Ethernet compatibility: • Preserve the Ethernet/802.3 frame format at the MAC Client Interface • Preserve the minimum and maximum frame size of the current 802.3 standard • Support full duplex operation only • Support star-wired local area networks using point-to-point links and structured cabling topologies • Support 802.3ad Link Aggregation • In other words: • Ensure compatibility with previous generations of Ethernet by preserving the MAC interface, frame format, and frame size

  7. 802.3ae 10GE Objectives -- Physical Layer • Objectives for native-Ethernet and SONET-friendly physical layers: • Support an optional Media Independent Interface (MII). • Support a speed of 10.000 Gb/s at the MAC/PLS service interface. • Define two families of PHYs: • A LAN PHY operating at a data rate of 10.000 Gb/s. • A WAN PHY operating at a data rate compatible with the payload rate of OC-192c/SDH VC-4-64c • Define a mechanism to adapt the MAC/PLS data rate to the data rate of the WAN PHY.

  8. LAN PHY vs. WAN PHY • Ethernet PHY - connects media to MAC • PCS (Physical Coding Sublayer) • e.g., 64b/66b coding, serializer and multiplexing functions • PMD (Physical Media Dependent) • e.g., optical transceivers • LAN PHY vs. WAN PHY • Operate over common PMDs • WAN PHY includes a simplified SONET/SDH framer • Simplified - reject conformance to SONET/SDH jitter, clock, etc.

  9. Optical Transceivers (PMD types) Minimum Distance Diameter PMD Fiber Supported At least 65m 50.0 850nm serial Multimode 62.5 At least 300m 1310nm WWDM Multimode At least 2 km, 10 km 9.0 Single Mode At least 2 km, 10 km 9.0 1310nm serial Single Mode At least 40 km 9.0 1550nm serial Single Mode

  10. Ethernet Changes Everything • Familiar technology and environment • Ethernet ‘end-to-end’ • Inherently scalable technology • Unmatched value proposition for data-optimized MANs • 1/5 the cost for equivalent bandwidth Ethernet 10 Mbs 100 Mbs 1 Gbs 10 Gbs OC3(155 Mbs) OC12 (622 Mbs) OC48 (2.4 Gbs) OC192 (9.6 Gbs) SONET/SDH

  11. Reliability Guaranteed QoS Voice centric Inefficient data transport Expensive Complex Lots of capacity and speed Low-cost Ubiquitous Ease of use Data-optimized Variable latency (Distance limitations) Traditionally LAN focused Technology Comparison Summary Ethernet SDH/SONET Pro’s Con’s

  12. TDMSwitch Voice Data Video Quality of Service • SONET/SDH well known for QoS • Guaranteed Bandwidth • Fixed latency • By reserving transmission time (timeslots)

  13. SONET/SDH style QoS for Ethernet • Reserve transmission timeslots • Classify by 802.1p/Q, DiffServe, TCP/UDP session, protocol, subnet etc • Rate shape (police) incoming traffic • Manage the Bandwidth • Bits/bytes per second • NOT packets/second – that’s CoS • Rate shaping (Policing) • Latency/jitter reduction • IP-TDM

  14. Bandwidth by the Slice Bi-directional Guaranteed! • Committed Information Rate (CIR) -type services for Ethernet • Bi-direct rate shaping • Control traffic on Egress • Police traffic on Ingress Min 15Mb/s Subnet X Max 30Mb/s Diffserve Min 5Mb/s VoIP
