An NDN Cache-Optimization Strategy Based on Dynamic Popularity and Replacement Value

چکیده
Aiming at examining the problems of low cache hit ratio and high-average routing hops in named data networking (NDN), this paper proposes a cache-optimization strategy based on dynamic popularity replacement value. When requested content arrives node, latest is calculated number requests current cycle previous cycle. We adjust node threshold according to occupation space with higher than threshold. complete, considers last request time, popularity, transmission cost cached calculate value content. move lowest out cache, keep high deploy proposed by using programmable language real network devices. The experimental results illustrate that can effectively improve reduce average for user responses compared other traditional NDN caching strategies.

An Adaptive Dynamic Replacement Approach for a Multicast based Popularity Aware Prefix Cache Memory System
In this paper we have proposed an adaptive dynamic cache replacement algorithm for a multimedia servers cache system. The goal is to achieve an effective utilization of the cache memory which stores the prefix of popular videos. A replacement policy is usually evaluated using hit ratio, the frequency with which any video is requested. Usually discarding the least recently used page is the polic...
متن کاملAn Efficient Data Replication Strategy in Large-Scale Data Grid Environments Based on Availability and Popularity
The data grid technology, which uses the scale of the Internet to solve storage limitation for the huge amount of data, has become one of the hot research topics. Recently, data replication strategies have been widely employed in distributed environment to copy frequently accessed data in suitable sites. The primary purposes are shortening distance of file transmission and achieving files from ...
متن کاملReduction in Cache Memory Power Consumption based on Replacement Quantity
Today power consumption is considered to be one of the important issues. Therefore, its reduction plays a considerable role in developing systems. Previous studies have shown that approximately 50% of total power consumption is used in cache memories. There is a direct relationship between power consumption and replacement quantity made in cache. The less the number of replacements is, the less...
متن کاملRule-Based Data Mining Cache Replacement Strategy
Caching in mobile environments is used for improving bandwidth usage and reducing query delays among resource constrained devices. It is used in multitudes of approaches. Some rely on the server occasionally broadcasting reports to inform clients of updated data while others permit clients to access data whenever they need it. Caching can be constrained by size and bandwidth; thus, coming up wi...
