Abstract EN:

We envision a decentralized middleware leveraging content-based networkingtechnology to mediate between information providers and informationconsumers at global scale, characterized by the scarcity of end-to-endbandwidth, the heterogenity of information consumer requirements andthe information overload. Content-based netwoking technology provides efficient disseminationchannels to information providers to reach information consumers in aloose coupled and decentralized manner, and has successfully contributedto the development of event-based applications supporting an exhaustivefiltering semantic i. E. Such that subscribers subscribe to all events matching a given predicate. We claim that the traditional exhaustive semantic is inadequate forglobal scale deployments and we have developped an original andscalable framework which defines an enhanced service model capturingthe quantitative and qualitative heterogeneity of informationconsumer requirements, and addressing the key design issues requiredto implement efficiently that service model. These design issuesinvolve efficient caching, forwarding and dissemination strategies.
