  1. ICFA Networking Task Force Workshop at CERN23-25 March 1998 “Key updates since September 1997” in Hungary Piroska Giese KFKI-RMKI

  2. European traffic • Hungary has a 10 Mbps connection to TEN-34 since May 1997 • The available capacity for the HUNGarian Academy and Research NETwork (HUNGARNET) is 5 Mbps • The country-wide IP backbone is called HBONE

  3. HBONE geographical Topology

  4. The country-wide Backbone - HBONE • the HBONE has a 30 Mbps ATM (PSV) core • most of the sites are connected via leased line with the speed of 64kbps - 1Mbps • the KFKI campus is connected via 2 Mbps microwave

  5. HBONE regional nodes and links

  6. Transatlantic traffic • via EuropaNET up to June 1997 • via direct MCI connection from June to November 1997 with a speed of 800 kbps • via TEN-34 US link since November 1997 The available capacity for the Hungarian R&D network is 5 Mbps

  7. Effect of the TEN-34 US link on the RMKI’s connectivity • Network monitoring is based on ICMP ping (the RMKI is a data collection site) • the average round trip delay and packet loss decreased to US sites • the packet loss increased to CERN and to European sites The problem is: The frequent break of the TEN-34 US link No backup is provided by DANTE

  8. Period of Ping15.10.1997 - 28.02.1998

  9. The counted average value of the ping results

  10. Traffic load control • The MRTG is running since January 1997 • The external traffic from/to KFKI campus is public available http://www.kfki.hu/mrtg/kfki-cisco.kfki.hu.2.html

  11. External traffic from/to Hungary • The Budapest - Vienna link is more then 50% loaded • The overview of line’s load is seen on the TEN-34 Weather Map http://www.dante.net/operations/statistics/weathermap.html

  12. TEN-34 Weather Map
