  1. RMDCN within RA VI- status and perspectives - Matteo Dell’Acqua ECMWF Matteo.Dellacqua@ecmwf.int CBS/ET-IMTN, 20-23 June 2001

  2. Contents • Background • RMDCN configuration • Network performance and reliability • Benefits and Developments • Future CBS/ET-IMTN, 20-23 June 2001

  3. Background • RMDCN Steering Group was established in 1994 • ITT was issued in March 1998 • Equant was selected as the provider for the RMDCN • Contract was signed in December 1998 • Service Commencement Date was 15 March 2000 • Contract runs for 5 or 8 years CBS/ET-IMTN, 20-23 June 2001

  4. The Network • Virtual Private Network based on Frame Relay PVCs • Guaranteed bandwidth ( CIR ) • Ability to take advantage of unused network capacity ( EIR ) • PVC costs are in function of the CIR and the location of the end-points • No limit to the number of Sites that can be connected • No limit to the number of PVCs that can be established • TCP/IP is used as a transport protocol • Fully managed Cisco routers • Connection via a PTT access line to the in-country POP • Backup service ( ISDN, PSTN, dual access line ) CBS/ET-IMTN, 20-23 June 2001

  5. Initial Deployment - membership • Deadline to be included was 1 April 1999 • Larger than anticipated, 31 countries in total • All 17 ECMWF Member States • Austria, Belgium, Denmark, Finland, France, Germany, Great Britain, Greece, Ireland, Italy, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and Turkey • 3 ECMWF Co-operating States • Hungary, Iceland and Slovenia • 11 Region VI countries outside ECMWF • Bulgaria, Czech Republic, Former Yugoslav Republic of Macedonia, Jordan, Latvia, Lebanon, Lithuania, Poland, Romania, Slovakia and the Syrian Arab Republic CBS/ET-IMTN, 20-23 June 2001

  6. RMDCN Configuration - 1 • Today, 32 countries + ECMWF are connected to RMDCN • Estonia was connected in December 1999 • Poland was connected in February 2000 • Croatia was connected in June 2000 • Syria • Regulatory issues are being resolved • Russia • Connection to UK Met Office • RMDCN Accession Agreement has been signed by Russia • Eumetsat • Connections to ECMWF and DWD by RMDCN circuits • Awaiting the approval of Eumetsat council CBS/ET-IMTN, 20-23 June 2001

  7. RMDCN Configuration - 2 CBS/ET-IMTN, 20-23 June 2001

  8. Reliability and Performance • Since 15 March RMDCN has been used for operational communications • Network very stable • Almost all PVCs get more than 99.5% availability • Number of problems reported to the local Help Desk is stable • Bandwidth delivered has been very good • EIR mechanism works very well and provides most PVCs with more bandwidth than requested CBS/ET-IMTN, 20-23 June 2001

  9. Service Availability CBS/ET-IMTN, 20-23 June 2001

  10. RMDCN repair time CBS/ET-IMTN, 20-23 June 2001

  11. RMDCN performance CBS/ET-IMTN, 20-23 June 2001

  12. Benefits - 1 • Upgrade of the GTS links and changes in the GTS configuration • Acceleration in the migration from X.25 to IP • A more flexible modernized network • New connections and changes can be easily introduced • Network is monitored by ECMWF on a 24h basis • Costs saving CBS/ET-IMTN, 20-23 June 2001

  13. Benefits - 2 • One point of contact for the RMDCN membership • uniformity • RMDCN Operations Committee • Co-ordination between all RMDCN participants • Network performance and reliability • Members are • All RTHs participating, 2 NMCs participating, WMO Secretariat and ECMWF • RMDCN Web Site • Set up by ECMWF to disseminate information on the project to the participating countries • RDT to diagnose network problems before opening a TT CBS/ET-IMTN, 20-23 June 2001

  14. RMDCN developments • New potential members • Countries are requesting pricing information to join the network • Some of the RTHs are considering to use the RMDCN for links to other GTS regions • Changes to the GTS architecture are likely to continue • New requests for bandwidth increases, mostly based on asymetric PVCs. • New request for Mission Critical connection. CBS/ET-IMTN, 20-23 June 2001

  15. Future - 1 • In response to the ITT, only Frame Relay solutions were offered • Large IP networks are being built by network suppliers for Extranet and intranet applications • Quality of service is becoming available for IP • More and more fibre networks are being built • New satellite communication networks are planned CBS/ET-IMTN, 20-23 June 2001

  16. Future - 2 • An all-IP solution • With higher link speed • With features such as IP multi-casting • With QOS to guarantee end-to-end traffic • Pilot an IP/VPN solution • Investigate the use of Internet VPN for backup CBS/ET-IMTN, 20-23 June 2001
