摘要： A method for providing chunked content to a device comprising a streaming client, preferably an HTTP adaptive streaming client, is described, wherein said chunked content is defined on the basis of a manifest file comprising one or more chunk identifiers and one or more associated chunk locators for locating one or more delivery nodes configured to deliver one or more chunks identified by said chunk identifiers, and wherein said method comprises: determining whether a chunk identified by a chunk identifier in a chunk request message originating from said client can be delivered by a first delivery node, said chunk request message comprising a first network address associated with said first delivery node, preferably said first network address comprising at least part of an IP address, an URL, or an equivalent thereof; if said first delivery node cannot deliver said chunk to said client, rewriting said first network address in said chunk request message into a second network address associated with a delivery node that is capable of delivering said chunk before sending said chunk request message to said second delivery node; and, before sending a chunk response message associated with said chunk request message to said streaming client, rewriting the second network address in said response message into said first network address.

摘要： The invention relates to a method, a system and various components of such a system for selecting a chunk identifier in a content delivery network. In said network a first and a second chunk are available, belonging to different quality representations of a content item. A client device transmits a first chunk retrieval request for retrieving a first chunk and a further request. In response to said first chunk retrieval request and/or said further request, delivery path information is transmitted. The delivery path information may comprise chunk identifiers and bandwidth indicators. On the basis of the delivery path information the client device determines a chunk identifier to be included in a second chunk retrieval request for retrieving a second chunk.
