Full duplex high-speed (100Mbps or more) end-to-end connectivity for large-scale deployment
Requires Cheap Hardware
AT&T Labs Low Cost Edge Node
• New high speed Access Network needed
• Cost dominated by switches and fibre installation
• Fixed Wireless Access is an alternative
An Integrated Wired and Wireless System
Ethernet Virtual Circuits
Home Appliances
• The Network Interface Unit connects all data services from the external Access Network to the home EVC network
• Streaming media, telephony and Internet access• Multiple media streams need high throughput, QoS and accurate

Prototype EVC switch
• Ethernet - cheap, simple, good mobility support
• Home systems will need Quality of Service (QoS)
• EVC unifies ATM and ethernet allowing multiple QoS priorities
• EVC is compatible with normal ethernet
