Research on the Cache Replacement Algorithm of Universal Network based on Cooling Mechanism

摘要

Universal network is a kind of typical separation network on identity or position, and it is one of the important trends of the new generation of networks. In this paper, identity mapping query process of universal network was analyzed and a beforehand push scheme of universal network was put forward in view of the main problems about time delay occurring in the identity mapping query process. On this basis, the access route cache partition scheme was given, and the access router cache replacement algorithm based on cooling mechanism was proposed. In the end, a detailed simulation experiment scheme was presented to validate that the method of replacement between pre-fetching and cache partition cooling was effective. The experimental results showed that the pre-fetching scheme of universal network identity mapping could effectively shorten the communication time delay of the mobile terminals, which improved the mobile supportive ability of universal network; furthermore, the access router cache replacement algorithm based on cooling mechanism can improve the routing cache hit ratio, which can shorten the routing time delay.
