Evolution – Contractual Changes (1)

 Supplement 1 – Dec 1999: minor change
 Supplement 2 – Jun 2002:
    -   Extension of the service beyond RA VI to other relevant NMC or organisations
        involved in the exchange of meteorological or related information as part of WMO
        or other international programmes willing to sign an Accession Agreement
        (background was if requested by WMO to implement connections to improve the
        GTS MTN).
    -   TAC recommendation regarding manpower:

             “Additional RMDCN members will inevitably lead to an increased workload for the RMDCN project team at

              ECMWF. If the third RMDCN staff member, foreseen from the beginning of the project, is authorised by

              Council in December 2001, the project team will be able to cope with a limited increase in RMDCN members.

              The addition of a modest number of connections between existing RMDCN members and WMO members

              outside RA VI, including the links that would be required for the IMTN project, can be supported without

              further staffing requirements. However, any substantial increase in RMDCN members would lead to

              additional manpower requirements.”

Evolution – Contractual Changes (2)

 Supplement 3 – Dec 2002:
     - major speed upgrade (including ECMWF funded “basic package”
       to 384 kbps)


 Supplement 4 – May 2006:
     -   Transition to IPVPN MPLS technology
     -   Major changes to Service Level:

              Mission Critical sites: 100% availability
              Sites with ISDN backup: 99.9% availability
              2 hour repair time
     -   Upgrade ECMWF funded “basic package” to 768 kbps



 RMDCN Steering Group, 4-6 June 2008, Vienna               Slide 9   ECMWF
Evolution – Architecture

 ECMWF checked regularly the status of new network
  architectures
 2004 proposal to migrate to MPLS
     -   Any-to-any connectivity with Class of Service concept
     -   Doubling of the access bandwidth
     -   Contract extension to March 2009
     -   Thereafter on a rolling basis for successive terms of 12 months

 Following signature on 8 May 2006, the implementation
  took 13 months and on 18 June 2007 the RMDCN was
  using a new IPVPN MPLS architecture
 Service Level
      24 * 7
      99.9% availability (100% for Mission Critical)
      2 hour repair time

Review


 Current contract with OBS started in Dec 1998 (~10 years
  on next BCR)
 An ITT process can take up to 18-24 months (and that
  from experience the implementation will suffer some
  delays), hence a new network service could only be
  implemented in 2010 at the earliest
 RMDCN Steering Group, 4-6 June 2008, Vienna                           Slide 13        ECMWF
Timeline for proposals
 2008
     -   January to March: Market Survey
     -   April:                  Annual Price Review with OBS
     -   Late spring:            Session of the RMDCN RA VI Steering Committee
     -   Summer:                 Session of the TAC Subgroup on the RMDCN
     -   Autumn:                 Report to TAC and to Council

Depending on the outcome
 2009
     -   March:                  Issue of the ITT
     -   May:                    Closing date
     -   Summer:                 Evaluation and contract negotiation

TAC Subgroup on RMDCN

 Established during 37th TAC in October 2007


 Terms of Reference

      to review the scope and methodology of the planned networking market
       survey;
      to examine the outcome of the market survey and make
       recommendations;
      to involve WMO/RA VI, WMO Secretariat and EUMETSAT as observers in
       the subgroup, as appropriate;
      to consider the consequences of any further expansion of the RMDCN to
       non-RA VI countries.
