Dynamically managing an operation of a content delivery network (CDN) to address excessive load upon an upload link for updating data thereto and/or upon particular portions of the CDN. A network optimizer may receive bit rate utilization data that identifies a current bit rate amount being utilized by the upload link and what digital video data is being uploaded to the CDN thereon. The network optimizer may also receive, from an analytic server, consumption information about the current load being experienced throughout different regions of the CDN. The network optimizer analyses the bit rate utilization data and the consumption information to dynamically render any changes necessary to the bit rate utilization of the upload link and to the representations of digital video propagated to some or all portions of the CDN to ensure the load remains below a predetermined threshold in both the upload link and throughout the CDN.

Dynamically adjusting load on an over-the-top (OTT) delivery network

A video server comprising an input port configured to receive from a user terminal requests to deliver video segments in a target representation. The server comprises an output port configured to deliver the requested video segments to the user terminal. The server comprises a data link configured to retrieve from storage capabilities, for each request from the user terminal, a video segment in at least one source representation in an Open GOP scheme. The server comprises an access to one or more video transcoding capabilities. The video server is configured to cause one or more video transcoding capabilities to transcode at least a part of the video segment in at least one source representation in an Open GOP scheme into the requested target representation in a Closed GOP scheme when the requested target representation is different from a representation previously provided to the user terminal.
