【摘要】：隨著網(wǎng)絡流量的急劇增長,現(xiàn)有的IP體系架構難以滿足用戶不斷增長的需求。CCN成為未來網(wǎng)絡研究的熱點,其最大的特點是網(wǎng)絡節(jié)點的處處緩存,所以為CCN設計一種高效的緩存機制顯得尤為重要。針對CCN中現(xiàn)有的緩存機制存在一些問題,提出了一種基于內容收益的內容流行度和節(jié)點重要度PBCS的緩存方案。在請求次數(shù)滿足收益標準的前提下,進行內容流行度與節(jié)點重要度的匹配,得到符合要求的緩存節(jié)點。仿真結果表明,該方案提高了內容的節(jié)點命中率,縮短了獲取內容的平均跳數(shù)。
[Abstract]:With the rapid growth of network traffic, the existing IP architecture is difficult to meet the growing needs of users. CCN has become a hot topic in the future network research. The biggest characteristic of CCN is the cache of network nodes everywhere. It is particularly important to design an efficient caching mechanism for CCN. Aiming at some problems in the existing caching mechanism in CCN, this paper proposes a caching scheme based on content revenue based on content popularity and node importance PBCS. On the premise that the number of requests meets the profit criteria, the content popularity and node importance are matched to obtain the cache nodes that meet the requirements. The simulation results show that the scheme improves the hit rate of content nodes and shortens the average hop number of content acquisition.
