Ethernet is the Unifying Technology
• Broadest range of speeds from 10M/s to 100Gb/s• Packet based networks end to end – no need to convert packets to cells• Service Provider Required Functions – Ethernet is becoming “Carrier
Grade”• Economies of Scale – Ethernet is the broadest deployed networking
