Retrospective
Advances in high performance networking achieved through R&E collaboration…
Some were long term joint activities Some were “proof of concept” over test bed environments Some were demonstration networks Some were product trials
…some worked well, some less well.

Paradigm Shift in REN requirements
“I need content accessible anywhere
at anytime” “I need application-based performance”
“I need dynamic bandwidth allocation”
“I need new, differentiated
services” “I need to protect my
network from students”
“e.g. 99.9999% availability” “e.g. Latency-based
routing”
“e.g. Bandwith on demand” “e.g. Secure
out-of-band signaling”
“e.g. Optical VPN”
NREN’s No Longer Want Dumb Pipes… They Require A Lot More From Their Networks

Can you provide 40GE connectivity through 37 different spans over a distance of more than 3000km through 3 different national networks as a foreign (alien) wave through infrastructure from several different vendors ? ….at a major public event where everybody will see if (or if it won’t) work.

Next Gen Modem Statement Of Work (SOW)
Next Gen Modem Technology Enables More Than Just 100G Transport
Core network 1000-2000Km, 3-5 50GHz ROADM,
(going to Grid-less), Good, un-
compensated, NDSF and NZDSF
Metro infrastructure
300-400Km, 10-16 100GHz ROADM (going to 50GHz), Challenged NDSF
MSO network edge Similar to metro but fewer ROADM (2),
already 50GHz
Submarine P2P to Trans-
Pacific, Compensated plant
Improve transport efficiencies Accommodate doubling of network traffic
Have a forward looking capability
High distortion mitigation For P2P submarine
For high PMD
Improve Spectral Efficiency (SE) New modulation schemes: QAM capable
Flexible grid operation: Pulse shaping
Improve operational economics New Ingress/Egress
Colour-less, Direction-less, Contention-less, Flexible grid
Enhancing the physical layer control plane Data mining
