"Versatility to better facilitate E2E..."
Versatility to better facilitate E2E services
Continue to provide quality IP transit services
Tune existing IP service platform
Optimise platform
Enhance resilience
Offer “Enhanced MBS” [or “lightpath” service]
“Wavelength” services for big users
Sub-wavelength services as well
Develop automated (“on demand”) provisioning and advance scheduling
Up to 10G
Endeavour to be prepared to implement 40G services


GÉANT2 BIG Users

"Connectivity:"
Connectivity:
a mix of DF and leased capacity, with a strong preference for DF where possible.
Equipment:
a mix of DWDM and switching technology
Both close to be concluded.


Service Scenarios
Considered three P2P user services:
Full [or partial] rate GEth
Full [or partial] rate 10GEth
STM-n
Considered three approaches for GÉANT2-NREN interconnection:
Physical GEth [+ VLANs]
Physical 10GEth [+ VLANs]
STM-16 or STM-64 [+ GFP/VCG]

Conclusion
GÉANT2 is designed to meet the demands of emerging high BW applications.
It aims to support e2e, multi-domain MBS [“lightpath”] signalling and setup.
It is, in GLIF terms, a Distributed Open Optical Exchange and one of the most important contributors to GLIF.
