GÉANT Services
slide4
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

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.

GÉANT 2 Connectivity and Equipment Procurement

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.
