10. October 2001K. Salah10 Is GbE Ethernet all over again? n Yes!!! A Thousand Times Yes. u Same frames u Same Knowledge u Same Infrastructure u Multiple vendor support u Low cost, interoperable u Simple, easy migration u Same network management philosophy u Very few new things to learn u Just the next step in Ethernet

17. October 2001K. Salah17 How about QoS? n ATM wins, but wait! u You need ATM all the way to the desktop u Most of LAN traffic is IP u With 1GbE PC-to-Switch, you have 2G bps BW to run any delay sensitive traffic. u MPLS, RSVP, and 802.1p are narrowing the QoS gap.

18. October 2001K. Salah18 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

25. October 2001K. Salah25 Summary n GbE is the most important new technology n GbE is very scalable n 10 GbE pt-to-pt will be 40 km over SMF n GbE is a switching technology, not a shared media. n GbE is winning (won) the war over ATM
