Gigabit Ethernet

DESCRIPTION

This resource explores Gigabit Ethernet (GbE) technology and its significant advantages over ATM, including scalability, cost-effectiveness, and ease of deployment. Dr. Khalid Salah from King Fahd University provides insights into the evolution of Ethernet technology, covering the future of 10 GbE, its integration into modern networks, and addressing challenges such as Quality of Service (QoS). The material also invites innovative research ideas related to GbE performance and deployment strategies. Discover why GbE is a leading choice for contemporary networking solutions.

  1. Gigabit Ethernet Dr. Khalid Salah Information and Computer Science Department King Fahd University of Petroleum and Minerals http://www.ccse.kfupm.edu.sa/~salah

  2. Why GbE? • ATM vs. GbE Conventional Wisdom? • Scalability of GbE? • Is 10 GbE just the beginning? • ATM vs. GbE • Deployment of 10 GbE • 80/20 rule!! • Any interesting research ideas? K. Salah

  3. WW LAN MarketHubs and Switches K. Salah

  4. Why Gigabit Ethernet? K. Salah

  5. Primary Drivers K. Salah

  6. Conventional Wisdom - 1994 K. Salah

  7. Conventional Wisdom – now! K. Salah

  8. Conventional Wisdom – 1994 K. Salah

  9. Conventional Wisdom – now! K. Salah

  10. Is GbE Ethernet all over again? • Yes!!! A Thousand Times Yes. • Same frames • Same Knowledge • Same Infrastructure • Multiple vendor support • Low cost, interoperable • Simple, easy migration • Same network management philosophy • Very few new things to learn • Just the next step in Ethernet K. Salah

  11. Scalability of Ethernet K. Salah

  12. Does the train Stop? K. Salah

  13. ATM vs. GbE K. Salah

  14. ATM vs. GbE K. Salah

  15. ATM vs. GbE K. Salah

  16. ATM vs. GbE K. Salah

  17. How about QoS? • ATM wins, but wait! • You need ATM all the way to the desktop • Most of LAN traffic is IP • With 1GbE PC-to-Switch, you have 2G bps BW to run any delay sensitive traffic. • MPLS, RSVP, and 802.1p are narrowing the QoS gap. K. Salah

  18. Deployment of 10 GbE • LAN: • both service provider and enterprise • MAN: • both dark fiber and DWDM • WAN: • Attachment to WAN access equipment at edge of OC- 192 infrastructure K. Salah

  24. Research Ideas? • Yes!! • Performance Study • Jumbo Frames • QoS • Etc. K. Salah

  25. Summary • GbE is the most important new technology • GbE is very scalable • 10 GbE pt-to-pt will be 40 km over SMF • GbE is a switching technology, not a shared media. • GbE is winning (won) the war over ATM K. Salah
