PRECISE GEOLOCATION FOR CONTENT CACHING IN EVOLVED PACKET CORE NETWORKS

摘要

A network element in a network is provided. The network element includes a receiver that receives a content request message. The received content request message indicates content to be transmitted to a device. The network element includes a processor in communication with the receiver. The processor generates a modified content request message by inserting identification data into the content request message. The identification data identifies at least one of a plurality of network nodes in the network. The network element includes a transmitter that transmits the modified content request message to a content distribution network server. The receiver further receives a redirect message that is based on the transmitted modified content request message. The redirect message identifies that a one of the plurality of network nodes is a cache location storing the indicated content.
