T-LAN
Why?
Why T-LAN with “High-End Users”?
• Mass user will be satisfied with FTTH
• Full-IP networks will be built out to support such an
extremely low-priced packet-based best effort services.
But this may not be enough to share ….
– e.g. 1Mb/s average x 30M subscriber = 30Tb/s
• Providers should find out yet another value added
service to share future lambda-rich infrastructure
• Who needs? – High-end users will do
– Performance is their first priority

T-LAN
Why?
What?
Today’s LAN (= Ethernet)
• Interface scales from 10M to 10Gbps per Host
– any to any, L3 transparent, and Plug & Play
• Diameter scales seamlessly from Local Area to Wide Area
– Host does not see any differences except for larger latency and jitter

Scope of “T-LAN” (Terabit Ether***?)
• Interface scales seamlessly from 10G to 1Tb/s per Host
• Diameter scales seamlessly from Local Area to Wide Area
– fiber propagation delay is inevitable, while it can be deterministic

T-LAN Concept
• Control plane on shared packet-based network
• Data plane on dynamically-assigned lambda-path network
– Number of lambda is determined by latency requirement

What?
T-LAN Targets
• Explore new or classic paradigms
– Multiple-lambda optical interfaces to end hosts
– Network facility shared by a lambda
– Dynamic lambda setup and release
• Provide extreme performance
– Multiple 10 Gbps capacity on demand
– Absolute low latency and fluctuation-less, just
distance delay
• Scale seamlessly from T-LAN to T-WAN
