  1. Middleware activities in Brazil and Latin America Liane Tarouco RNP2

  2. Midleware in Brazil • Although there is no broad midleware effort underway in the academic community here, there are a number of promising activities in the areas of PKI and directories within Brazil

  3. Public key certification services • In the research and education community, several universities have begun to offer their own public key certification services, and a demand has already been expressed for integrating these separate initiatives. • Certification authorities • federal govern • universities

  4. ICP - Brasil • ICP-Brasil (Infra-estrutura de Chaves Públicas Brasileira) • E-gov effort in Brazil • All direct administration organizations(including universities) are suposed to use certification authority of ICP-Brasil • http://www.icpbrasil.gov.br/

  5. PKI at national level • On a wider scale, public key certification was the object of legislation here in 2001, and a formal PKI hierarchy was defined, with the root CA being run by the federal government. • The federal government has also largely limited the circulation of printed documents, having replaced these by their digital equivalents.

  6. Interoperation • Some initiatives are also being taken for interoperation of digital certification technology with neighboring countries.

  7. RNP

  8. RNP - Rede Nacional de Pesquisa • RNP has begun a development project to promote the use of directory technology within the academic community. • GT-Diretórios (directory work group) • Noemi Rodriguez • http://www.rnp.br/pd/gt-diretorios/

  9. RNP GT-Diretórios • Schemas being considered • eduPerson • LDAP Recipe • DoDHE- Directory of Directories for Higher Education • Multinstitutional • Identification, authentication and resources allocation

  10. server LDAP API's LDAP LDAP API aplication navegation: ldap_search() ldap_result() ldap_first_entry() ... Java C Perl

  11. DSML • Standard proposal for XML • Directory Services Markup Language • Oasis proposal • description • data • operations

  12. DSML server LDAP • Proposal: servers implement DSML interface DSML translator dsml-LDAP aplication LDAP DSML

  13. Motivation • Integrate & unify information management • Catalog service • Directory of users • Directory of Directories (DoDHE) • Others • information about equipment and network configuration • metadata

  14. RNP pilot experiments • Pilot applications include support for • video on demand • certification for grid computing.

  15. Certification authorities in universities • UFSC - Univ. Fed .Santa Catarina • http://ac.labsec.ufsc.br/ • UFRGS - Univ Fed. Rio Grande do Sul • authentication ADSL users • interconnection between Brasil Telecom and UFRGS backbones (ATM 155 MBPS)

  16. Certification authorities in universities • UFMG - Univ. Fed Minas Gerais • LDAP - 30.000 entries • academic/administrative community • integrated with Lotus Notes

  17. Middleware experiments • Study and implementation of directory service using LDAP for supporting collaboration in project METROPOA (Metropolitan Area Network of the Porto Alegre area)

  18. Other efforts • X.500 • ISODE (UFRGS) • Paradise Name Flow • Project DUNGA - Diretório Unificado Gerenciamento Aberto • Users & researchers of the academic network in state of Rio Grande do Sul

  19. Video applications • Integration with digital video digital work group (GT-VD) • http://www.rnp.br/pd/gt-vd/ • Guido Lemos • Usage on VoD service • Available titles (and localization) • User access control • Secondary servers • Equipment configuration

  20. Vídeo on demand • UFRGS • Sincronization video & slides • Sincronization video and legend • SMIL and Real • Directory for information about multimedia resources

  21. Directory for Learning Objects Metadata • IEEE P1484 – Leaning Objects Metadata

  22. Grid efforts in Brazil • Initial efforts starting in scope of CENAPAD (Centros Nacionais de Computação de Alto Desempenho) • SINAPAD - Sistema Nacional de PAD) • CESUP/UFRGS

  23. Grids and directory • Globus: toolkit for supporting grid applications • LDAP: • information about computational resources • static • dynamics

  24. QAME • QoS-Aware Management Environment • Network Management environment for QoS aware • QoS management • Maintenance • Monitoring • Analysis and inspection of QoS • Chairman: Lisandro Z. Granville

  25. QAME • LDAP schema adapted from IETF • MIB for policy transfer • Policy Decision Point (PDP) implemented on a Linux router for supporting POPs (Policy of Policies) • QoS monitoring using sniffers and Linux router • MIB for monitor control • MIB for scheduling of monitoring activity

  26. HTTP SNMP LDAP SNMP Pilot experiment MetroPoa 2

  27. Latin America • Human resources capacitating phase • seminaries • courses

  28. Midleware in Brazil and LA
