ABSTRACT = {Named Data Networking (NDN) is one of the most excellent future Internet 
architectures and every router in NDN has the capacity of caching contents passing by. It 
greatly reduces network traffic and improves the speed of content distribution and 
retrieval. In order to make full use of the limited caching space in routers, it is an urgent 
challenge to make an efficient cache replacement policy. However, the existing cache 
replacement policies only consider very few factors that affect the cache performance. In 
this paper, we present a cache replacement policy based on multi-factors for NDN 
(CRPM), in which the content with the least cache value is evicted from the caching 
space. CRPM fully analyzes multi-factors that affect the caching performance, puts 
forward the corresponding calculation methods, and utilize the multi-factors to measure 
the cache value of contents. Furthermore, a new cache value function is constructed, 
which makes the content with high value be stored in the router as long as possible, so as 
to ensure the efficient use of cache resources. The simulation results show that CPRM 
can effectively improve cache hit ratio, enhance cache resource utilization, reduce energy 
consumption and decrease hit distance of content acquisition.},
