Abstract

The invention refers to methods and devices for responding to a streaming request (S). In order to allow for efficient network layer access at locations within an access network (11) where network elements (21) are installed that operate on the data link layer, a method for responding to a streaming request (S) related to a content stream (CS) to be delivered by a content delivery network (27) to a node (23) connected to a private network (13) of a customer of an operator of a fixed access network (11) is provided, wherein the method (41) comprises receiving (45) the streaming request (S); determining (47) a source address (N) of the streaming request (S);deciding (49) on whether the request (S) shall be served by a content delivery network entity (33) belonging to the private network (13), wherein the deciding (49) is based on the determined source address (N); and returning (57) an address of the content delivery network entity (33) to the node (23) if a result of said deciding is that the request shall be served by the content delivery network entity (33).

Description

technical field [0001] The present invention relates to a method for responding to a streaming request and a server operable to perform such a method. Furthermore, the invention relates to access nodes and methods for operating access nodes as well as customer premise equipment and methods for operating customer premise equipment. Background technique [0002] Content Delivery Networks (CDNs) are well known in the prior art. When distributing content with a large size (such as video and / or audio streams or files) to a large number of devices over the Internet or any other Internet Protocol (IP)-based network, resulting in scalable sexual issues. Specifically, the server may be overloaded, or the connection used to connect the server to the IP-based network may become a bottleneck. [0003] A content delivery network has CDN nodes installed closer to certain groups of devices within the topology of the network. CDN nodes maintain their own copies of content, so they can d...
