Gianni,José Luis Status Message Switching System Status Message Switching System Corobor Messir COMM Replacement for ageing DEC Alpha Server 2100 in end of 2005 allowed rapid migration to TCP/IP protocols. Hardware: HP M350 3G, running OS. Windows Hot stand-by facilities.

Gianni,José Luis Status Message Switching System (continuation) Status Message Switching System (continuation) Shortcomings Since operational innumerable software bugs were found. So far many patches were installed. Some of the problems still persists. Low performance for the data volume that RTH Buenos Aires manages. Inefficient technical Support. Curently TDCF/TAC features are not supported. Starting from the next month RTH Bs. As. is going to count on aTrial version of IBL Moving Weather software.

Gianni,José Luis Status Internet Status Internet Internet Conventional Bandwith 17 Mbps. Autonomous system. Internet2(no commercial) Bandwith 2 Mbps Used internaly to collect both land and sea based observations. Used to disseminate commertial products and uncommertial public services. Used as a backup to comunicate GTS Data with other NMCs Centres. FTP Widely used internaly and externaly(sftp)

Gianni,José Luis RA lll RMDCN-Status of implementation- RA III President and PRs of Argentina, Brasil and Peru met in WMO headquarters in order to discuss present- day problems and to setting up a strategy to implement “one and for all” the RMDCN; In this regard the meeting agree: To Constitute a small working team conformed by representatives from Argentina, Brasil, Peru and Venezuela. whose mission is to develop a network design proposition according to the Region technicals options and contractual implications.

Gianni,José Luis As it is very well known it is expected RTH Buenos Aires (and Brasilia) join Cloud I in a short time, so that some effors are made to include budgetary for the next year. Status IMTN

Gianni,José Luis RTH BUENOS AIRES Joining Cloud I

Gianni,José Luis RTH Bs. As. joining Cloud I (budgetary figures)

Gianni,José Luis Goals Goals GTS GTS Urge NMCs joint the new RMDCN project proposal (whatever it be). Encourage NMCs to install IBL METDATA Software in order to implement IWM. Suggest NMCs to implement an eficcient mechanism to collect/diseminate their own internal data. Recommend installations of VPN (Ipsec tunnels) replacing current NMCs plain Internet access. For a better outcomes would be appropiated address the last issues to a PR level.

Gianni,José Luis Relevant Facts Relevant Facts Migration of land and X25 satelital links to TCP/IP. Expanding of Internet Bandwith (14 to 17 Mbps) Multiple agreements with universities, public and private organism and institutions, etc, preparing the ground to become a DCPC.. Strong authoritie’s support to WMO programms.
