一种基于网内缓存协助的缓存机制研究

Research on cache mechanism based on in-network cache assist

移动数据网络流量的大幅增长导致终端用户无法接受的延迟和移动运营商传输成本的大幅增长。为此,提出了基于网内缓存协助的eNodeB缓存机制,提高其缓存性能,以实现eNodeB在缓存中的高效应用的方法。通过网内缓存的信息优化eNodeB的本地缓存决策。通过从实际网络中采集到的真实流量数据,对所提出的缓存策略进行了实验验证。结果显示该机制能显著降低网络延迟和带宽消耗。

The significant increasing in traffic on mobile data networks results in unacceptable delays for end users and a signifi- cant increase in mobile carrier transmission costs. In order to solve this problem, an eNodeB caching mechanism based on intra- cache caching is proposed, its cache performance is improved to realize the efficient application of eNodeB in the cache. Optimizing local caching decisions of eNodeB through cached information within the network. Through the real traffic data collected from the actual network, the proposed cache strategy was experimentally verified. The results show that this mechanism can significantly re- duce the network delay and bandwidth consumption.
