  We study a discrete-time wireless network that serves both cacheable and
non-cacheable traffic with assistance of a relay node with storage capabilities
for both types of traffic. We investigate how allocating the storage capacity
to cacheable and non-cacheable traffic affects the network throughput. Our
numerical results provide useful insights by varying not only the allocation of
cacheable to non-cacheable storage but also the rate by which non-cacheable
content is transmitted, the rate by which cacheable content is requested, as
well as different popularity distributions of the cached files.
