命名数据网中基于流行度的网内缓存替换策略
Novel caching replacement strategy based on popularity in named data networking
摘要
Abstract
How to effectively solve the cache replacement problem in the NDN(Named Data Networking)nodes,this paper puts forward a strategy"Po-Rep"to predict the popularity of all every cache chunk stored in the node. When a cache chunk traverses from the hit nodes, the strategy determines the coming cache chunk which will be stored in the node replacing the one with the least value.According to the request frequency and request time interval of the cache chunk,this strategy accurately predicts the popularity of the content in the node.So that all of the contents in a node can maintain the maximum value,which can satisfy the following user requests.The simulation results show that this strategy can improve the hit rate in the stored nodes of the network,reduce the server load and improve the overall performance of the Named Data Networking.关键词
