Abstract

A method and system for micro-cloud computing is described. An application serving node, which is a specifically configured piece of customer premises equipment such as a set-top box, is the server for a micro-cloud network. Various user devices that form part of the micro-cloud network, such as television sets and smart phones, communicate with the application serving node. The application serving node is configured with software that allows various heterogeneous types of data to be obtained and streamed to the user devices in multiple ways. The application serving node performs much of the processing necessary for such content streaming itself and thus represents an edge-based network architecture.
