  1. 1. Publish/Subscribe communication mechanisms over PSIRPAugusto Morales DominguezTechnical University of Madrid, Spain
  2. 2. OUTLINEMotivationBackgroundArchitectural ProposalImplementationSummary and Conclusions
  3. 3. MOTIVATION CURRENT INTERNET The Internets evolution has turned into a mixture of protocols, architectures… that bring an unnecessary complexity in the way MIGRATION MECHANISMS nodes access to information. Trends: - Incremental Internet design - Clean Slate Internet design FUTURE INTERNET
  4. 4. MOTIVATION The information centric approach: information consumers do not have to concern about the information source. This is a different approach from the current host- centric network which todays Internet is based on. The Publish/Subscribe communication mechanisms - Publishers - Subscribers - Rendezvous/Brokers
  5. 5. BACKGROUNDPSIRP(Publish/Subscribe InformationRouting Paradigm): a newarchitecture for the Internet Design a new information-centric internetworking architecture based on the publish-subscribe paradigm Clean Make “information” the center of attention Slate and remove the “location-identity split” that plagues current networks Implement and validate the new architecture under realistic operational scenarios.
  6. 6. BACKGROUNDPSIRP(Publish/SubscribeInformation RoutingParadigm Information from single piece of data, to large documents or video files are structured in hierarchical publications. This way of information organizing via flat and independent labeling (Sid,Rid)
  7. 7. BACKGROUNDPubSubHubbub protocol (PuSH)An open server-to-server protocol for distributed communication over the Internet using Atom and RSS as a source format.
  8. 8. ARCHITECTURAL PROPOSALBased on: PubSubProxyHub (PSPH)
  9. 9. ARCHITECTURAL PROPOSALPuSH/PSIRP Layer Topology
  10. 10. IMPLEMENTATION1. Validating ScenarioPubSubhubbub Scenario Ej: Href URL (topic) generated in Pubsubhubbub: http://psph.ericsson.com/atom/stream/alice http://psph.ericsson.com /atom/stream/alice Convertion Function sId rId (Scope Identifier) (Rendezvous Identifier) 256 bits 256 bits
  11. 11. IMPLEMENTATION1. PuSH Communication Diagram
  12. 12. IMPLEMENTATION2. Validating ScenarioChat Application for verifying bi-directional communication between Isolated TCP/IP Networks
  13. 13. SUMMARY AND CONCLUSIONS It is clear that even with a nearly perfect network, migration mechanisms are necessary. It is essential to define interoperable solutions with current Internet services and future Internet . The architecture proposed in this paper accomplishes interoperability between the future Internet architecture PSIRP, which is under active evolution (EU FP7 PURSUIT Project) Finally, other issues have been addressed such as: subscription mapping and conversion of different identifiers…
  14. 14. MOTIVATIONThe Internets evolution FUTURE INTERNET has turned into a mixture PATH of protocols, architectures… that bring an unnecessary complexity in the way nodes access to Clean Slate Incremental information.
  15. 15. MOTIVATION The information centric CURRENT INTERNET approach: information consumers do not have to concern about the information source. MIGRATION MECHANISMS The Publish/Subscribe communication mechanisms - Publishers - Subscribers FUTURE INTERNET - Rendezvous/Brokers
