Actually [December 2003], the link to the INTERNET is 1 fast link [100mbps], which is shared with obspm.fr [Paris site].
There are 3 possibilities to increase the bandwidth :
update to a gigabit link : the most expensive, needs to change a network hardware + software
add 1 or 2 more fast links to the same node [RAP]
add 1 link to RENATER the last 2 solutions should need only software upgrade, and also "agreements" from the network managers at RAP, RENATER,and obspm. In all cases, it needs software upgrade on various network hardware.
