A method of processing information centric networking (ICN) interest messages in a delay tolerant networking (DTN) scenario, wherein ICN data mules receive interests for content from end-users and disseminate content to end-users based on the interests and/or during encounters with other ICN data mules, includes performing a popularity estimation of content; appending, by a first end-user when forwarding an interest for given content to a data mule, a nonce to the interest; and employing, by a first data mule, the appended nonce according to predefined rules to maintain and/or record a counter for interests for the given content. The counter functions as a popularity indicator for the given content.

A method delivers content in content delivery networks that include an upstream content delivery network and a downstream content delivery network comprising at least two content delivery entities. The upstream and downstream content delivery networks are connected to each other. A user equipment is connected to the downstream content delivery network. The method includes requesting a content stream by the user equipment, providing the content stream by the upstream content delivery network, redirecting the content stream to a content delivery entity, and providing the content stream to the user equipment. Network information of the downstream content delivery network and/or user equipment information are determined. Probabilities for the content delivery entities are determined for optimized content stream performance. The user equipment is connected to the content delivery entity having the highest probability. The content stream is redirected to the content delivery entity and delivered to the user equipment.
