In-network caching, one of the characteristics of Content Centric Networking (CCN), allows the contents to be cached along the delivery path. This makes the subsequent request(s) to obtain the cached content copies without visiting the original sources. Thus an appropriate cache management scheme could enhance the CCN network performance tremendously. In this paper, two optimal cache replacement strategies Time to Hold (TTH) - LFU and TTH-LRU are proposed, which not only consider the features of video delivery on CCN but also take the future requested popularity into account. Our goal is to reduce the cache storage redundancy and to improve the network performance while costing quite limited overhead. In our simulation, we compared our scheme against two widely accepted cache replacement policies LRU and LFU on 4 different hybrid topologies with variable cache sizes. The result shows that for every scenario, our schemes significantly improve the cache hit ratio and shorten the total communication time as well as the average hop count, and lighten the burden imposed on the original sources. Furthermore, our proposal can decrease the excessive network traffic, which avoids the unnecessary data delivery among routers and reduces the transmission energy consumption 20% on average from LRU and LFU. Besides, we evaluated the impact of several factors to demonstrate that how other factors affect the performance of our proposed cache replacement schemes. |
