Real contrasts depending on where « you » are :Real contrasts depending on where « you » are :

• Geographical location

• University policy / strategy concerning IT

For many (campus) still a long way to goNot for the larger ones

French networking infrastructure three (even four) storeyed rocket

Problems deriving from that situation :• disparity between national and regional ambition• different timings

regional-networks.version-X and Renater.version-X+1• different communities served

Key pointsKey points : :

Network backbones at Gbits/s with :

• reliability (organisational and infrastructure issues)

• security (VPNs),

• implementation of CoS. [VoIP, Videoconf, …]

10 Mbits/s really available to the end users (100 if needed)

• less than 10 as a factor of overallocation

First versions in early 90’s now in « version 2 » for mostFirst versions in early 90’s now in « version 2 » for mostNot running as fast as RenaterNot running as fast as RenaterReasons ? Reasons ? (be careful, no true in every case)(be careful, no true in every case) : :

« regional governments » not convinced but the specific needs of the research and higher education community,

No competition no real alternative level of costsNo involvement of our community in the final engineering

of the network (the operator provide a multiservice stuff), ending up as a « blackbox », not even magic

And neveretheless they are essential in our model.

To day they are the weakest links.

is correctly connected, several others may not be
