Coded caching is a technique to reduce network loads.
Recent works have discussed single-layer caching systems, but many networks consist of multiple layers of caches.
In this paper, we discuss coded caching problem for a hierarchical network that has a different number of layers.
The networks have users who connect to an origin server via mirror servers and users who directly connect to the origin server.
In our previous work, we have provided three basic schemes for this network setting and characterize these schemes.
In this paper, we provide lower bounds for our network setting and propose a novel scheme by combining these two basic schemes.
In addition, we provide achievable rates and show that proposed combination scheme demonstrates good performance by a numerical result. |
