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?

Is GbE Ethernet all over again?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

How about QoS?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.

Deployment of 10 GbEDeployment 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

SummarySummary
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
