  1. 10 Gigabit EthernetMarket and Technology Overview David O’Leary Director, Consulting Engineering

  2. 10 GbE Market Overview • Extension of existing Ethernet family of standards • Another 10x jump for higher capacity • Typical Ethernet applications at higher speed • Also positioned as a MAN/WAN technology for use over dark fiber or SONET/SDH

  3. 10 GbE Applications: Intra-POP Connectivity Aggregation Layer Customer CPE IP Core Routers & Switches 10GE Intra-POP; SONET to WAN Optical Core 10 GbE

  4. 10 GbE Applications: Internet Peering ISP 1 10 GE (Private) ISP 4 ISP 2 10 GE 10 GE 10 GE 10 GE ISP 3

  5. 10 GbE Applications: Server Connections Customer Cages Co-Location Facility Layer 4-7 Switches, Servers Optical Core 10 GE Connections IP Core Direct Attachment

  6. 10 GbE Applications: MAN or WAN SONET or dark fiber 10 GbE

  7. 10 GbE Technology Overview • Retention of 802.3 MAC and frame format • 64 – 1518 Byte frames • Jumbo-frames not included in standard • No half duplex mode • different from other versions of Ethernet • No CSMA/CD on full duplex • Simultaneous sending and receiving at all times • Works with 802.1Q, 802.3ad, etc. • Fiber interfaces only – no copper versions • LAN PHY – 10Gb/s • WAN PHY – 9.29Gb/s (SONET framing overhead)

  8. 10GbE Terms and Acronyms • PHY – PHYsical Layer Device • PMD – Physical Media Dependent • WIS – WAN Interface Sublayer • SONET rate and framing adaption • WWDM – Wideband Wave Division Multiplexing • XGMII – 10Gb Media Independent Interface • XAUI - 10Gb Attachment Unit Interface • XENPAK electrical interface • Replace or extend XGMII interface (lower cost) • XENPAK • consortium agreement for interoperability of 10Gb transceiver modules • Keyed Floating Duplex SC optical connector • PHY and PMD independent

  9. 10GbE Media Types • 10GBase-SR – up to 300m over dark fiber • 10GBase-SW – up to 300m over SONET • Both 850nm, multimode fiber • 10GBase-LR – 2m-10km over dark fiber • 10GBase-LW – 2m-10km over SONET • Both 1310nm, single mode fiber • 10Base-ER – 2m – 40km over dark fiber • 10Base-EW – 2m – 40km over SONET • Both 1550nm, single mode fiber • 10GBase-LX4 – 4 parallel wavelengths over single multi- or single-mode fiber pair at 1310nm

  11. Standardization Status and Schedule • IEEE 802.3ae Working Group • Work began in 1999 • Project approved in January, 2000 • Currently at “Sponsor ballot” status • See IEEE web page for gory process details • http://grouper.ieee.org/groups/802/3/rules/ • Draft 4.3 is most current • Continuing to resolve various technical and editorial comments • Significant changes unlikely at this point • Final Standard quite likely in 2002 • Tentative June 13th ratification

  12. Interoperability Status • May ’02 NetWorld+ Interop network test • 13 companies participated with 19 devices • Variety of switches, test equipment, fiber and components were included in the network • 4 of 7 Media types included • Chip level interconnect (XAUI) also tested http://www.10gea.org/10gea_pr_050702.pdf

  13. Summary and Conclusions • 10 Gigabit Ethernet is viable now • Standard is basically complete • Products are shipping • Switch and router interfaces • Test equipment • As with all new technology: • Test for interoperability, check interoperability test results (UNH IOL, Interop, etc.) • Test for performance (interface and system)
