  1. Work-Package 5: MAMA-NET Objective: • To initiate a data and information exchange system (Net-MedGOOS) that will support: • Exchange of operational metadata / data between agencies • Access to operational products for MAMA partners Partners: • NCMR, ENEA, IFREMER, IOLR, ICM, IOC, IMBC + new providers • IMC, IOI-MOC, NIB, DFMR, IMS-METU, CNR-S2AM, IOR, ANPA (users) MAMA 3rd Progress meeting, Rome June 2003

  5. Task 5.1.1: Networking Requirements B3 Description of Networking capabilities of the Product Recipient. • B3.1 Type of connection to the Internet: Dial-up(33.6KB/56KB), ISDN (64KB or 128KB), ADSL, Leased line (please specify speed xx mBs.) • B3.2 Type of computer used to access Internet: PC, Mac, Unix Workstation (HP, IBM, SGI, Sun, DEC/Compaq, Others.)  • B3.3 Operating System: Windows (95/98/ME/NT/2000/XP), MacOs, Unix, Linux  • B3.4 Protocols mainly used to access data: HTTP, FTP, Other (please specify) • B3.5. Software used to access data: Internet Explorer (IE), Netscape, FTP client, Other (please specify) MAMA 3rd Progress meeting, Rome June 2003

  6. Task 5.1.1: Networking Requirements (cont) B.5 Description of Networking capabilities for Product Providers • B.5.1 Estimated product volume (xx Mbytes) • B.5.2 Update Frequency of products (event based; daily; weekly; monthly; yearly) • B.5.3 Location of the server hosting the products: Local server inside the area of the institute, Remote server outside institute • B.5.4 Access to the products: (Free access, licensed/dedicated enquiry, on-line/restricted access) • B.5.5 Protocols used in the server side for accessing the products: HTTP, FTP, Other (please specify) • B.5.6 Number of simultaneous user sessions: 0-50, 50-100, 100-500, over 500 • B.5.7 Type of server connection to the Internet: ISDN(64KB or 128KB), DSL, Leased line (please specify speed in MB/sec) • B.5.8 Networking responsible person and contact details MAMA 3rd Progress meeting, Rome June 2003

  7. ‘Product providers’ answers MAMA 3rd Progress meeting, Rome June 2003

  8. ‘Product providers’ : Summary of the answers Estimated product volume:Depends on the type of data/information and the relevant format used for their dissemination: 100-200 MB (4), 15-30 MB (2), 1,5 MB or less (5) Update frequency of products :Daily basis (6), Seasonal / yearly basis (4) , Non-periodic basis (2) Operating system used for product provision :UNIX/Linux (8), MSWindows (6), Both (2) MAMA 3rd Progress meeting, Rome June 2003

  9. ‘Product providers’ : Summary of the answers (cont) Location of server and protocol used:Local (10), Remote (2) - HTTP (7), FTP(1), Both (4) Access to the products :Free (7), Restricted (5) Number of simultaneous users:Up to 50 (8), Up to 100 (1), Up to 500 (1), Over 500 (1) Line capacity :64-128Kbps(2), ISDN-ADSL (3), 2Mbps(3), 10Mbps (3) MAMA 3rd Progress meeting, Rome June 2003

  10. ‘Product providers’ : Summary - Conclusions • In most cases the volume of data is quite small (max. 15 MB) and only four partners will provide data larger than 100 MB. This is also related to the data format used since in only six cases raw data are distributed. • The majority of partners have an open policy for their products, providing free access to everyone. Concerning the data update frequency, this is done in most cases on a regular basis (daily: six records, seasonally: three records) • The data exchange protocols are common to all partners and are based on HTTP/FTP. Eight institutes rely on UNIX/Linux platforms for their product dissemination while four partners use MS-Windows for this service. • According to their statements, the data providers can support the data flow along MAMA-Net, since in almost all cases (9 out of 12) the Internet connection line speeds are over 1Mbit/sec. Even for providers that use lower speeds, no problems are foreseen for the pilot operation of MAMA-Net either because the amount of data is small or because the update frequency is low.

  11. ‘Product recipients’ answers

  12. ‘Product recipients’ : Summary of the answers Connection to Internet: up to 56Kbps (7), 64-128 Kbps (2), ISDN-ADSL (6), 500Kbps (1), over 2Mbps (7) Type of computer used to access Internet : PCs (17), Unix Workstation (3) Operating System : MS Windows (20), Unix/Linux (6) Protocols used : HTTP (23), FTP(10) Software used : Internet Explorer (13), Netscape (1), FTP client (3) MAMA 3rd Progress meeting, Rome June 2003

  13. ‘Product recipients’ : Summary - Conclusions • There are cases (seven records) inside MAMA-Net where the type of connection to the Internet (standard dial up lines) cannot be considered as adequate for uninterrupted data flow, especially when access to model outputs is needed. • The standard Personal Computers (PCs) are mainly used for receiving data and the MS-Windows is the most popular operating system on user side. • The data exchange is based in all cases on HTTP (mainly) and FTP protocols and the MS-Internet Explorer is the software most commonly used.
