Cache (DANE) arranged along a transmission path between a client terminal and at least one server, said cache (DANE) being configured to receive, from the client terminal, a request for at least a first representation of a segment of a multimedia content available at several representations, which comprises:
- a bandwidth estimation module (7) configured to determine a first downstream bandwidth along a transmission path between said cache and a downstream network element, arranged between said cache and the client terminal;
- a communication module (2) configured to deliver, when the first representation is not cached by said cache (DANE), a response to the client terminal comprising an alternative representation of said segment, which is cached by said cache (DANE) and which associated bitrate is less than or equal to the sum of the first downstream bandwidth and a first threshold. |
