Technical network Implementation


We managed to convince


Got agreement


Huge Logistic problem


Call for tenders, deliveries, stock management, etc


A lot to install !


Adaptation of services


New switches


Database & tools extensions


New features to study & deploy


Clock distribution, Multicast, QoS,…


Integrated
, with the GPN, into one single 24x24, 365x365

And LHC physics!!!…


The LHC project is not only the machine


Physics at the pits


Very large and complex systems to install


Will start end 2003 for the (large) infrastructures


Computer Center farms challenge


Solutions for installing network for 10000s of
nodes


Operating such large systems

Services High Availability


GPN Backbone redundancy:
Implemented


DHCP: Redundant services:
done


Technical Network:
part of

the challenge


CSAM


ST/EL: Better power feeds…


DNS: soon to improve


Spectrum everywhere, 24x24.

Soon to come


Better network access control


Pilot High density 100 base
-
T to the desk


All database based applications move to WEB
interfaces including MTP (si, si!)


LANDB2 in January


LANDB3 mid 2003 will fully Integrate
Network/Register and LANDB2


All services moved to Intel/Linux


End of NCDs


DXCOMS off …


Thank you!
