System and control protocol of layered local caching for adaptive bit rate services
A system for layered local caching of downstream shared media in a hierarchical tree network arrangement includes a first network node on a first distribution network having a first caching controller. The first network node configured to store a video segment transmitted on the first distribution network based on a first instruction received by the first caching controller from a central caching controller communicatively coupled to the first distribution network. The central caching controller is located upstream from the first network node. The system includes a second network node on a second distribution network having a second caching controller and communicatively coupled to the first network node. The second network node configured to store a video segment transmitted on the second distribution network based on a second instruction received by the second caching controller from the first caching controller.
