1. ICFA Networking Task Force Workshop at CERN 23-25 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

8. 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

9. Period of Ping 15.10.1997 - 28.02.1998

10. The counted average value of the ping results

11. 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

13. 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
