- 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
Israel connected to the RMDCN (June 2011 - 1 Mbps Mission Critical)
South Africa is being connected (2 Mbps Mission Critical)
Very reliable
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
6RA VI workshop on WIS implementation, Sofia, 1-3 November 2011
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
7RA VI workshop on WIS implementation, Sofia, 1-3 November 2011
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
