3. Research Overview - Application-driven resource provisioning for distributed contents delivery over optical network Challenges – How to guarantee diverse application QoS requirement in sparse-splitting optical network – How to support parallel streaming for real-time media delivery Possible solution – Hierarchical approach for MC- RWA based on virtual node Minimize the wavelength channel cost for multicast session QoS-driven multicast routing in optical network – Transport layer parallel streaming Rate coordinator: Dynamic rate control based on the network condition Content coordinator: Data segment assignment to multiple replicas.

4. Paper Roadmap Photonic Netw. Commu. WOC’08 IEEE/OSA JOCN International Conference (TBD) International Conference (TBD) Heuristic algorithm for interactive real- time media Focused on the hierarchy- based approach Suggest the ILP formulation for optimal solution Present the optimal MC- RWA for media streaming (using parallel connections) IwQoS’08 IEICE or other SCI journal Present the functionality for parallel TCP streaming Suggest the relationship between rate and contents coordinators Propose the basic conceptRefine/develop the concept Parallel streaming with consideration of optical network constraints ~ Aug. 2009~ Dec. 2009 ~ 2008 Present the combination solution of two topics
