提出了一种新的网络共享Cache技术--分组Cache,通过把所有的共享Cache按其在网络中的位置进行分组,该方法能够有效地解决多Cache组织查询效率不高和I／O瓶颈等问题.该技术有以下特点:①采用分组技术能够有效地降低多Cache间的查询开销;②组内的Cache数据目录表能够很快确定请求的内容是否在某个Cache中;③根据网络访问日志确定的分配算法能够较好地平衡各Cache组的负载.模拟测试证明:分组Cache技术与其他已有的共享Cache技术相比有较高的效率.
This paper proposes a new network shared cache technology, packet cache. By dividing all shared caches according to their location in the network, this method can effectively solve the problem of inefficient query and I / O bottleneck in multi-cache organization The technology has the following characteristics: ① using packet technology can effectively reduce the query overhead between multiple Cache; ② Cache data directory within the group can quickly determine whether the requested content in a Cache; ③ According to the network access log The determined allocation algorithm can balance the load of each Cache group well.Modeling tests show that Packet Cache technology has higher efficiency than other existing shared Cache technologies.
