Rede Nacional de Ensino e Pesquisa - RNP • RNP is a “quasi non-governmental Rede Nacional de Ensino e Pesquisa - RNP • RNP is a “quasi non-governmental organisation” (quango), formally a non-profit company, maintained by the federal government through a mangaement contract • Offers production IP service to research and education community in Brazil, through a national backbone (one Po. P in each state) – Around 240 client institutions, normally connected to state networks (in the more populous states), or directly to the local Po. P • Good national and international connections to R&E and commodity networks • Responsible also for exploring new networking technologies and developing new networking techniques – IP/WDM, multicast, Qo. S, IPv 6 Rede Nacional de Ensino e Pesquisa Promovendo o uso inovador de redes avançadas no Brasil

What is the Isabel application? Isabel is a real time service creation environment launched What is the Isabel application? Isabel is a real time service creation environment launched in 1993 by UPM. Today, it is commercialised by Agora Systems S. A. • A free version is available, with limited functionality. The commercial version includes more features and supports collaboration services such as tele-teaching and teleconferencing. • The aim is the interconnection of a large number of users in multipoint conferences. • Rede Nacional de Ensino e Pesquisa Promovendo o uso inovador de redes avançadas no Brasil

What is the Isabel application? Isabel adapts collaboration sessions to users’ needs, by including What is the Isabel application? Isabel adapts collaboration sessions to users’ needs, by including predefined scenarios: Tele-meeting: links meeting rooms and allows a free mode of interacting, allowing each participant to react at any moment. • Tele-training: links classrooms and allows a strict floor control by the instructor of the interactions taking place. In this case, the instructir can bring any site into scene at any moment and students must request intervention. • Tele-conference: this is a distributed conferencing service and is based on centralised control which guarantees timely delivery of content. • Other new services can be configured by modifications to existing services. • Rede Nacional de Ensino e Pesquisa Promovendo o uso inovador de redes avançadas no Brasil

What is the Isabel application? System requirements: Based on Su. SE Linux 8. 1 What is the Isabel application? System requirements: Based on Su. SE Linux 8. 1 operating system. Both the operating system and the application can be installed and configured using an instalation CD. • • Requires at least a Pentium IV with 256 MB RAM.

Impressions about the use of Isabel • Different versions of Isabel cannot interoperate with Impressions about the use of Isabel • Different versions of Isabel cannot interoperate with each other The hardware requirements are very important to assure good quality during the conferences. • The use of an operating system different from Su. SE can make it difficult to configure Isabel. • The use of a chat software (IRC) was very important to prepare the endpoints and resolve the problems with audio and video. • Isabel doesn’t support the same quality that a endpoint specific equipment, such as a Polycom View. Station or Tandberg Station, but represents a very good solution for distance education or collaboration when there is a need for a large number of endpoints. • Rede Nacional de Ensino e Pesquisa Promovendo o uso inovador de redes avançadas no Brasil

Performance problems during the experiment • The quality of the link used is very Performance problems during the experiment • The quality of the link used is very important. A big problem found during the experiments was the packet loss at the connection between the RNP and Telefônica networks in São Paulo • probably due to inadequate RNP router capacity at the peering point – will be fixed for “next time” • Rede Nacional de Ensino e Pesquisa Promovendo o uso inovador de redes avançadas no Brasil

Conclusion • This was the first demonstration in Brazil of a non-trivial application over Conclusion • This was the first demonstration in Brazil of a non-trivial application over IPv 6 • Except for the performance problems, which are unrelated to the technology used, the experiment was considered to have been a success – Participants were very enthusiastic and contributed a lot of time and energy to the project • Most important lesson: IPv 6 will only really prosper when the users can see advantages in its use – this requires the availability of significant applications. • Many thanks to all partners and participants!
