- 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

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

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
