Content delivery by a network node is optimized. The network node is communicatively coupled between multiple end user devices and at least one content service provider. A request for a media streaming service available from the content service provider is intercepted from a first requestor device. It is determined if the media streaming service is registered for delivery optimization based on at least one service rule specific to the media streaming service. It is determined if a second requestor device is currently receiving the media streaming service from the content service provider. In response to the media streaming service being received by the second requestor device, delivery optimization of the media streaming service is performed by replicating the media streaming service for delivery to the first requestor device. The replicated media streaming service is sent to the first requestor device.
