Welcome to DISEDAN project


The DISEDAN (service and user-based DIstributed SElection of content streaming source and Dual AdaptatioN) project proposes an evolutionary solution to enhance the content delivery via Internet. It focuses on research in the area of multi-criteria content source (server) selection and handover, considering user and server contexts.

Two main concept will be analyzed:

  • Two-step server selection mechanism which allows for cooperation between Service Provider (an entity offering the content distribution service, but owning or not a network infrastructure) and End User making use of innovative algorithms that consider context- and content-awareness.
  • Dual adaptation mechanism applicable during media session that combines the advantages of Media adaptation and content server handover in a single solution.

The proposed streaming system will be able to function as a standalone client application, without any modifications applied to the Service Provider (SP), as long as the SP is able to provide a list of available and appropriate servers to the client. If, additionally, the SP is able to provide to the client some other additional information helpful for the initial client decision, then an optimised server selection results. Consequently, the project outlines a set of optional Provider side modifications (w.r.t. useful information and metrics provided by SP to the client) that can further optimize server selection. The design of the system takes backwards-compatibility into consideration, ensuring that both client and Service Provider side modifications work well with the other side using existing content distribution solutions.

DISEDAN is a project of European Coordinated Research on Long-term Challenges in Information and Communication Sciences & Technologies ERA-Net.
