Transatlantic link
- HEPTEL kept as partial lifeline
To CERN on 64 kbit/s leased line (plus compactors X2)
Runs fromCERN to US on part of CERN line
- US link carried on 45Mbit/s ‘T3’ link since June-1997
UKERNA statistics show WWW traffic~90%
Worse during working day in term time !
- This month: A second 45 Mbit/s link has been installed
-
- Basically an IP service
-
- ! But includes a UKERNA router at the US access point
(which may allow some optimisation of routing)
