Caching is the most effective practice for reducing delays and congestion in networks aimed at content distribution. In this work we address the setup of multiple Internet service providers (ISPs) sharing a federated cache. When multiple ISPs with different demands share a cache, storage cost can be reduced when the cache is coded, that is, storing objects that are XORs of multiple content objects.
The talk will present our results on low-complexity methods for coded caching, where both computational complexity and communication cost are minimized. For the static-demand case we show how to lower the computational complexity to serve requests while guaranteeing optimal storage cost. For the dynamic-demand case (ISPs constantly changing their demands), we propose an architecture and algorithms to lower the communication cost required for updating the coded objects in the cache, while maintaining low storage cost.
