摘要
针对安装缓存时的代价问题,从缓存的存储代价和未命中代价之间的平衡考虑,通过数据建模的方法,首先提出了分层缓存模型,分析了该模型可以确定缓存开销代价最小时的最佳容量,但也有自身的局限性,于是进一步提出了单缓存容量模型,通过模拟试验表明,该模型可以有效的确定一个最佳缓存容量,在保证较好命中率和字节命中率的前提下使缓存的代价最小。
I n this paper, according to the problem about the cost of deploying cache, consideration of the balance between the storage cost and the miss cost of the cache, using the method of data modeling, firstly, a hierarchical caching model is proposed, the model can determine the optimal capacity which has least cost, but this model also has its own limitations. Then, a single buffer capacity model is proposed, Simulation experiments show that the model can effectively determine an optimal buffer capacity, in the premise of ensuring better hit rate and byte hit rate, the cost of the cache is minimized.
