Abstract: A content delivery system for delivering an audio and/or video content to a mobile terminal is deployed on top of a mobile network and includes plural edge cache servers arranged using a star or hierarchical topology. The edge cache servers are connected to respective aggregation nodes of the mobile network such that a configurable breakout function of the nodes enables routing thereto packets addressed to an anycast addressing associated with the servers. When receiving a request, from the mobile terminal, for obtaining a manifest file of the audio and/or video content, an edge cache controller of the content delivery system creates a session identifier including a unicast addressing part pointing to the controller, and redirects the mobile terminal to the anycast addressing of the servers. The servers then obtain the session identifier from the mobile terminal and use the unicast addressing contained therein to receive context information from the controller.
