Abstract: A managed multimedia delivery network (1) for providing a multimedia service with resilient service quality is disclosed. The network comprising a plurality of caching nodes (3) for caching multimedia data segments; an edge caching node (4) for colleting requested multimedia data segments from the caching nodes (3) and for serving a user equipment (2) with the collected multimedia data; and a service gateway (5) for providing cache information to the edge caching node (4) indicating how to obtain the requested multimedia data segments from the caching nodes (3). The edge caching node (4) comprises a service quality monitoring unit for monitoring the collection of the data segments from the caching nodes (3) and for requesting cache information from the service gateway (5) when the collection of data segments impacts the service quality.

Abstract: Methods and systems are provided for guaranteed quality multimedia service over managed peer-to-peer networks (also known as super peer-to-peer, sP2P, networks). A managed peer-to-peer network (1) for providing a guaranteed quality multimedia service is disclosed. The network comprises at least one caching node (3) for caching multimedia data segments; an edge caching node (4) for serving a user equipment (2) with multimedia data; and an admission logic (5) for checking whether a service request from the user equipment (2) is admitted for a required quality of service, wherein only service requests resulting in media sessions for which the required quality of service can be guaranteed are admitted.
