System and method for simultaneous optimization of source selection and traffic engineering

摘要

A 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 content sources that store the data are represented as virtual routers that are each connected to a common virtual content server by respective infinite capacity communication links; determining optimized routing through the network topology for the data from the virtual content server to the receiving device; and determining, in dependence on the optimized routing, a data allocation for each of the content sources to transmit data through the network to the receiving device.
