RA VI Workshop on the implementation of WIS

Sofia, Bulgaria, 1-3 November 2011

Matteo Dell’Acqua - Météo France

Chair TT on RMDCN


Session 3 wis telecommunication

Session 3 – WIS telecommunication

RMDCN

Satellite communication & multicast

Discussion


Rmtn configuration

RMTN configuration

  • - The majority of the links are through the RMDCN

  • - The number of additional circuits on bilateral agreement has increased

    • Easy to implement additional links through the Internet and cloud network services

  • A few Internet based circuits

  • The number of non-operational circuits is 7

  • - Remarkable improvement in circuit speed

  • - Satellite broadcasting systems are available to complement to the GTS


Rmdcn configuration

49 sites are connected

45 National meteorological services

35 from RA-VI

ECMWF

EUMETSAT (2 sites)

1 disaster recovery site for The Netherlands

RMDCN Configuration

  • Israel connected to the RMDCN (June 2011 - 1 Mbps Mission Critical)

  • South Africa is being connected (2 Mbps Mission Critical)

  • Very reliable


Rmdcn

RMDCN

  • From 64 kbps to 8 Mbps

  • 2 access circuits or 1 circuit + backup

  • Some RA-VI countries have not joined RMDCN, mainly due to cost concerns.

    • This situation is not likely to change in a near future

  • 2nd WMO Task Team on the RMDCN 28-29 June 2011 at ECMWF, Reading

    • Topics related to the requirements for the next generation of the RMDCN were discussed

  • RA-VI Workshop on next generation RMDCN in spring 2012


Eumetcast overview

EUMETCast Overview

DVB-S file based satellite dissemination system

>2900 Users in RA-VI

Tellicast multicast reception software using off the shelf PC and antenna systems

  • RETIM and DWDSAT as third party dissemination services for RA-VI on EUMETCast

  • EOPortal at EUMETSAT for user registration and data discovery


Internet

Internet

Primary link for some NMHS

Through VPN connexions

To get additional bandwidth at affordable costs

ECMWF products

Backup method for RMDCN sites

Operational DMVPN-based solution managed by ECMWF

Access method to the MPLS cloud
