  2. Previous External Connectivity • 6 * 155 Mbit links • Peer in Hudson St. • 622 Mbit to Esnet • 622 Mbit to Abilene. ICFA SCIC Meeting CERN Mar 02 R. Hughes-Jones Manchester

  3. New External Connectivity • 6 * 155 Mbit links • 2.5Gbit line installed • IP commodity peer in London • Research traffic over 2.5G bit • Peer in Hudson St. • 622 Mbit to Esnet • 622 Mbit to Abilene. ICFA SCIC Meeting CERN Mar 02 R. Hughes-Jones Manchester

  4. Monitoring: US Traffic UKERNA Traffic data Kbit/s. Blue Traffic from US; Maroon Traffic to US 7 day periods 1 hour averages 14 Jan 2002 (800Mbit/s) peak 86% of total 930 Mbit 17 Jan 2002 Peering altered 22 Jan 22 Jan 2002 Weed day peak 175 Mbit/s Weekend-Before Weekday-After Weekday-Before ICFA SCIC Meeting CERN Mar 02 R.
