In the recent years, Information-Centric Networking (ICN) that
mainly focuses on contents that are transmitted and received instead
on end hosts that transmit and receive contents has been under the
spotlight.
In the literature, there have been several studies on contents
caching, which is one of notable features in ICN.
Specifically, the effectiveness of contents caching, efficient
caching algorithms, and optimal cache allocations to ICN routers
have been actively studied.
Several solutions for the cache allocation problems, which are
formulated as combinatorial optimization problems have been
proposed. However, it is not well understood how the optimal cache
allocation is affected by several factors such as the network
topology and the total cache size.
In this study, by combining our performance analysis of ICN on an
arbitrary network topology and conventional heuristic for
optimization problems (i.e., genetic algorithm), we investigate the
optimal cache allocation to routers while changing the network
topology and the total cache size. |
