Abstract: A method and request router (RR) are provided for dynamically pooling resources in a Content Delivery Network (CDN), for efficient delivery of live and on-demand content. The method comprises receiving, at the RR, a request for a content from a client, determining a content type associated with the request for the content, the content type being one of: live content and on-demand content. The method also comprises, based on the determined content type, dynamically electing, at the RR, delivery nodes at edge, region or core for content delivery and grouping the dynamically elected nodes into a resource pool, selecting a delivery node within the resource pool for delivering the content and sending a response to the client including an address of the delivery node selected within the resource pool to be used to get the requested content.

Abstract: A network node (20) operative to adjust chunk size is provided. The network node (20) includes processing circuitry (34) having a processor (36) and memory (38). The memory (38) includes executable instructions which, when executed by the processor (36), configure the processor (36) to: determine at least one measured 5 performance characteristic associated with the network, dynamically adjust a chunk size for caching each of a plurality of segments of at least a portion of content, cause transmission of a content request, according to the dynamic adjustment of the chunk size, for at least one segment of the plurality of segments of at least the portion of the content. The dynamic adjustment of the chunk size is based on the at least one 10 measured performance characteristic associated with the network.
