You are sitting on aquarter terabit Lan!

Check your seats!

You have a network connection of 1 Gigabit/s in

your chair!

250 seats * 1 Gb/s ->0.25 Tb/s

How to define a Terabit/s LAN?• Depends where you put the boundary!

– Backplane of a switch?

• What is the functionality– Many times point to point (dwdm/wss/mems)– Broadcast/multicast capabillity– Packet service versus streaming

• Application requirements– Packet services or streaming

• LAN-WAN interface– Addressing (mac -> ip)– Routing to the edge of the system– Integrate LAN and WAN

So, is a Terabit LAN just a bigger ethernet switch?

If yes: just wait and buy!

So, is a Terabit LAN just a bigger ethernet switch?

If yes: just wait and buy!

Why no:Grid -> collective services!Anti-statistical behavior!

Towards Hybrid Networking!• Costs of optical equipment 10% of switching 10 % of full routing equipment for

same throughput

– 10G routerblade -> 75-300 k$, 10G switch port -> 5-10 k$, MEMS port -> 0.5-1.5 k$

– DWDM lasers for long reach expensive, 10-50 k$

• Bottom line: look for a hybrid architecture which serves all classes in a cost

effective way ==> map A -> L3 , B -> L2 , C -> L1

• Give each packet in the network the service it needs, but no more !

L1 ≈ 1 k$/portL2 ≈ 5-10 k$/port L3 ≈ 75+ k$/port

Cost of 1 Tb/s LANvery rough estimate sept 2005

• L2– 10 gig nic ~ 1 k– Per L2 switch port ~5 k– Total 6 M

• L1– Per L1 port ~ 1 k– Total 2 M

• OOPS, I forgot the cables and the power bill
