2. Evolution of R&E Networks
Early days - 56 kbps
NSF T1 Network
NSF T3 Network
Privatization
vBNS OC-12 primarily
Abilene OC-48
Current Abilene OC-192
Trend to larger bandwidth circuits
Is this trend about to end? Parallelization? Change in Architecture?
What does the community want now?

3. Beyond 10 Gbps
It is possible to saturate a 10 Gbps backbone with flows between two PC class machines
Recent flows across the Abilene network have reached 9.5 Gbps using dual bus PCs having dual Ethernets
Research networks have applications that require large flows across long distances
On commercial networks, most data flows are small
Parallelizing may be sufficient to add capacity
What are the economic effects/factors?
Technology exists
40 Gbps modulation techniques
Muxing at various levels
Economics of higher bandwidth circuits

4. Questions
What are the technological directions, both LAN and WAN – 40 Gbps? 100 Gbps?
Optics and electronics?
Parallel and single optics?
Practical limitations?
Limitations of parallelization at layers two and three?
What are the driving applications?
What are the economic incentives?
Impacts of Standardization?
Timeframe? 40 Gbps? 100 Gbps?
