Network solutions for Analysis
Working remotely (i.e. use FNAL CPU) is not so bad:
- 4Mb/sec / 64 users = 64kb/sec/person = run PAW at FNAL from Xterm in Italy, more then needed.
- still need internet to copy docs, printouts etc.. Note: presently WWW to Fnal downloads at ~20 kbit/sec and is just fine.
Will mostly run at FNAL and ship DHL large ntuples and small or often needed PADs (20TB = 200tapes, already handled in Run I that many Exabyte). Copy short ntuples (?100Mbit) on the net (keep transfers < 1hour)
This requires little more then present bandwidth, e.g. ~2 Mbit/sec for CDF probably OK.
BUT: need to run analysis jobs at FNAL, desperately needs better interactive response: now 300msec per key (ping from TS, BO, PS), unacceptable ! Interactive must be priviliged. Low throughput is OK, but response time must be shorter.
