WORLD METEOROLOGICAL ORGANIZATION _________________________ COMMISSION FOR BASIC SYSTEMS OPAG ON INFORMATION SYSTEMS & SERVICES JOINT IMPLEMENTATION-COORDINATION MEETING ON THE GTS-WIS MTN AND MEETING OF THE CBS EXPERT TEAM ON GTS_WIS OPERATIONS AND IMPLEMENTATION (ET-OI) GENEVA, 23 - 26 SEPTEMBER 2008 ISS/ICM-MTN&ET-OI 2008/Doc. 2.11 (--.IX.2006) ENGLISH only STATUS OF RTH MOSCOW (Submitted by Expert (Russian Federation)) ________________________________________________________________ Summary and Purpose of Document This document includes the report on the status of implementation of telecommunication centre and circuits at RTH Moscow ________________________________________________________________

2. Message Switching System in RTH Moscow was replaced in 2000. It consists of two sub-systems: operational and standby. MSS network software is based on TCP/IP procedures. In addition, there are a limited number of asynchronous connections. Russian broadcast system “Meteoinform” is also integrated to the system. TCP/IP Socket (Special) and FTP/WMO: are the basic data exchange protocol used. E-Mail: Messages can be received or transmitted via e-mail. WWW: A/N messages and FAX charts can be received via web-interface. Current status of RTH Moscow (1)

3. Links of RMDCN OBS/Equant (Exeter, Prague, Sofia, Norrkoping, Beijing, New-Delhi, Bucharest) were migrated from F/R to IPVPN MPLS network in June 2007 with success. Bandwidth of some links were extended during 2007-2008: - RTH Novosibirsk up to 128 Kbps - RTH Khabarovsk up to 256 Kbps - NMC Minsk up to 128 Kbps Current status of RTH Moscow (2)

4. Establish backup connection to RTH Melbourn and RTH Sofia through Internet VPN Upgrade the B/W of RMDCN access circuit up to 1 Mbps Migrate Moscow-Tbilisi, Moscow-Baku, Moscow-Erevan, Moscow-Kishinev, Moscow-Almaty links to RMDCN or establish digital lines with these NMCs. Upgrade next circuits: Moscow-Khabarovsk up to 512 Kbps Moscow-Novosibirsk up to 512 Kbps Moscow-Minsk up to 256 Kbps Moscow-Kiev up to 128 Kbps Future plans:

11. Russian broadcast system “Meteoinform” infrastructure The broadcasting is carried out in the C-band through 4 Russian satellites (Expres AM1, Expres AM3, Expres AM11 and Yamal-200) providing the coverage of the whole territory of the Russian Federation and a number of adjacent countries.

13. Internet infrastructure There are three connections to Internet via three different Internet Service Providers for exchanging the operational data and collecting NCEP products from RTH Washington.

14. GISC DCPC NC NC NC NC The general technical decisions on development of the Russian GISC/DCPC prototype In 2008 the tender for the research work including as one a problem, construction of the prototype Russian GISC is declared. The general architecture and interaction Picture 1 is presented the classical scheme of construction of interaction GISC - DCPC (in view of direct interaction GISC – NC). The general framework of the Russian segment of information system WMO (prototype GISC - Moscow – DCPC-Obninsk) is supposed to build on the basis of solutions of (End-to-end, E2E) technology and providing E2E development for maintenance of full standards and functionality according to WIS Technical specifications.

15. The general technical decisions on development of the Russian GISC/DCPC prototype (1) The architectural approach on the basis of client-server technology with «mediator/wrapper» mechanism is used: • mediator is a software which, on the one hand, cooperates with the users of integrating system, and, on the other hand, with the removed data sources; • wrapper (or the adapter) is the intermediary between mediator and local system of data. The wrapper carries out functions of a data source. With regard for the approach indicated the main components of the Russian GISC-DCPC prototype are the follows: • Portal – registration of the users, data/products search using the system metadata catalogue, data visualization or saving on user computer • Integration Server (mediator) – metadata management (accumulation, harvesting, synchronization, etc.), access/upload the DCPC (NC) metadata and data via Data Provider software • Data Provider (adapter) – local data registration, metadata generation, provision of access to data

16. The general technical decisions on development of the Russian GISC/DCPC prototype (2) And: It is planned to use: 1) Integration Server at GISC level for interaction with DCPC (NС) and others GISC, and at DCPC level for interaction with NC and GISC; 2) Data Provider at DCPC(NC) centers; Data Provider will have two version: “full” – connection with local data and generation of metadata automatically; “light” – remote registration data source and interaction with Integration Server. Under this version the DCPC(NC) generates the metadata by own software as proposed canonical WIS framework.

17. The general technical decisions on development of the Russian GISC/DCPC prototype (3) • The Data Provider (NC level) is intended for interaction with local data systems of NC, placed in the organizations – participants of Russian GISC. The Integration Server at GISC level is responsible for DCPC/NC metadata management and data acquisition from DCPC/NC and transfer to their external users (GISC Portal). The Integration Server at DCPC level carries out similar functions concerning NC’s of zone of the DCPC responsibility. The GISC Portal realizes a single-enter in the integrated system, search and data presentation. • Functionality of the prototype, as a whole, will meet the Technical Specifications of WIS (special actions for check are planned): • registration of users (the Portal + the Integration Server); • search of data through metadata base (the Portal + the Integration Serve); • accumulation and synchronization of metadata, realization of request/response, sample and delivery of data (the Integration Server + the Data Provider); • local metadata updating (the Data Provider).
