A mediation framework for multimedia delivery

We present a conceptual mediation framework that features three layers of mediators: presence, integration, and homogenization layers that work together in a peer-to-peer (p2p) manner to facilitate the delivery of multimedia data. On arrival of each request for data from a client1 , a global-mediator is elected from a group of integration layer mediators to service that request. Using distributed hash table (DHT), the globalmediator dispatches the request to other integrator mediators to track down the data sources. Upon receipt of the results, from the source(s), the global-mediator presents the data to the client via a presence-mediator. The presence-mediator may need to reformat the data to suit the execution context of the client. This mediation process is context-aware, adaptive and dynamically structured. Quality of service (QoS) factors are taken into consideration in the retrieval and presentation of data. Keywords Mediator, middleware, heterogeneous data sources, multimedia d...
