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
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
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.
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)
BACKGROUNDPubSubHubbub protocol (PuSH)An open server-to-server protocol for distributed communication over the Internet using Atom and RSS as a source format.
ARCHITECTURAL PROPOSALBased on: PubSubProxyHub (PSPH)
IMPLEMENTATION2. Validating ScenarioChat Application for verifying bi-directional communication between Isolated TCP/IP Networks
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…
