system and method for joint source selection and traffic engineering optimization

摘要

method and system for routing data in a content distribution network (network) from a plurality of content sources that store the same data to a receiving device, including generating a network topology in which each of the sources of Content that stores data is represented as virtual routers that are each connected to a common virtual content server by their infinite capacity communication links; determining optimized routing through the network topology for data from the virtual content server to the receiving device; and determining, depending on optimized routing, a data allocation for each of the content sources to transmit data across the network to the receiving device.
