Clean Slate Design - O Que é?

  1. 1. Clean-Slate Design Alberti
  2. 2. Tópicos  Definição  Competências e Foco de Pesquisa  Esforços Clean-Slate  Considerações Finais
  3. 3. Definição  Reiniciar do zero com o que já se sabe hoje o desenvolvimento de arquiteturas, protocolos e sistemas de comunicações visando resolver os problemas atuais e construir soluções mais inteligentes, adaptativas e que fazem melhor uso dos recursos de transmissão, energia, memória, etc., sem ter como limitante a manutenção da compatibilidade com os sistemas atuais.
  4. 4. Competências e Foco de Pesquisa  Tecnologias de Comunicação x Análise de Desempenho  Tecnologias de Comunicações:  ATM, VoIP, SDH, Gigabit Ethernet, WiMAX, VCat, GFP, LCAS, NGN, MEGACO, Parlay, SIP, NGN-GSI, IPTV-GSI, Ad-hoc Wireless, WPAN, Clean-Slate Design, Optical Networks  Análise de Desempenho:  Modelamento, Teoria de Filas, Simulação por Eventos Discretos (Tool3), C++, Inteligência Artificial 

  12. 12. Esforços Clean-Slate  Stanford  Flow-level Models for the Internet, Fast Dynamic Optical Light Paths, Rate Control Protocol, NetFPGA Platform, Enterprise Network Security, Virtual Worlds, Open Platform Switch. CPU Memory - Open source PCI - 4 portas de 1GbE - US$500 1GE FPGA 1GE 1GE Memory 1GE http://tiny-tera.stanford.edu/~nickm/talks/GEC%20March%202008%20McKeown.ppt
  13. 13. Esforços Clean-Slate  Stanford  Open Platform Switch A “pragmatic” compromise Allow researchers to run experiments in their network… …without requiring Standard User- Experimenter writes sw Network defined vendors to expose hw Processing Processing experimental code on switch/router Internal workings. Nick McKeown http://tiny-tera.stanford.edu/~nickm/talks/GEC%20March%202008%20McKeown.ppt
  14. 14. Esforços Clean-Slate  Clean Slate Design Project  O objetivo é levar 100 Mbps para 100 milhões de norte americanos.  Focado na arquitetura da rede.  “Que decisões de projeto faríamos se pudéssemos projetar tudo novamente?”  “With clean slate design, is it possible to simultaneously simplify network and protocols and increase network dependability, economic sustainability, and security?”  Documentação disponível bastante desatualizada... http://100x100network.org/presentations/100x100OverviewMay05.ppt
  15. 15. Esforços Clean-Slate  FP7  Dezenas de projetos em várias áreas. http://www.future-internet.eu/ http://www.itu.int/dms_pub/itu-t/oth/29/01/T29010010010001PDFE.pdf
  16. 16. Esforços Clean-Slate  FP7 – SENSEI  “In order to realise the vision of Ambient Intelligence in a future network and service environment, heterogeneous wireless sensor and actuator networks (WS&AN) have to be integrated into a common framework of global scale and made available to services and applications via universal service interfaces.” http://www.sensei-project.eu/
  17. 17. Esforços Clean-Slate  FP7 – 4WARD  “The need for structural changes in the Internet is becoming increasingly evident. 4WARD is combining a set of radical architectural approaches building on a strong mobile and wireless background to design inter-operable and complementary families of network architectures.”  “Until recently, the common vision of a future ubiquitous network was based on the continuing evolution of the IP family of protocols and networking techniques. Now, however, senior researchers accompanying the IP development from its beginning have started to ring the bells as the IP evolution seems, for several reasons, to be coming to a critical turning point.” http://www.4ward-project.eu/ http://www.4ward-project.eu/index.php?s=file_download&id=5
  18. 18. Esforços Clean-Slate  FP7 – EIFFEL  “Today’s Internet was never designed to be a critical part of the European economy infrastructure - but it has become exactly that. In the light of these developments, there are many questions today on how the Internet will develop in the future. It is apparent that the Internet must change and that the change is likely to be revolutionary. It is expected that today’s Internet will evolve into the “Future Networked Society”. http://www.fp7-eiffel.eu/ http://www.fp7-eiffel.eu/fileadmin/docs/EIFFEL-FINAL.pdf

  23. 23. Esforços Clean-Slate  FIND – Future Internet Design  “Invites the research community to consider what the requirements should be for a global network of 15 years from now, and how we could build such a network if we are not constrained by the current Internet -- if we could design it from scratch.” Researcher  Mantém outros projetos: Ambient Networks e Extreme Wirelessing: Prototyping a Future Global Network.  Pouca coisa na Internet. http://www.nets-find.net/ http://www.itu.int/dms_pub/itu-t/oth/29/01/T29010010010001PDFE.pdf
  24. 24. Considerações Finais  Grande diversidade de pontos de vista e propostas.  Certo consenso de que para avançar é preciso mudar de forma mais radical.  Para alguns somente a reestruturação completa permite certos ganhos hoje impossíveis de serem alcançados.  Formas de migração para as novas redes aparecem nas discussões.  Em algumas propostas o aspecto simplicidade é tido como relevante (continua valendo o paradigma KISS).
