Hierarchical Caching via Deep Reinforcement Learning

Wireless and wireline networks, such as Internet, cellular, and content delivery networks are to serve end-user file requests proactively. To this aim, by storing anticipated highly popular files during off-peak periods, and fetching them to end-users during on-peak instances, these networks smoothen out the load fluctuations on the back-haul links. In this context, several practical networks comprise a parent caching node connected to multiple...
