我们考虑位于边缘云中的数据/内容缓存系统，其由每个服务的多个代理共享（以降低成本），例如，一组数据驱动的物联网设备。每个代理在共享缓存中操作其自己的具有一定容量的LRU列表。同时出现在多个LRU列表中的对象的长度在它们之间相等地划分，即，在LRU之间共享对象。我们给我们的MemCacheD与对象共享（MCD-OS）原型的数值结果。此外，一个工作集近似的共享高速缓存的描述和如何减少涟漪驱逐进行了讨论。
We consider a data/content-caching system located in an edge-cloud that is shared (to reduce costs) by a number of proxies each serving, e.g., a group of data-driven IoT devices. Each proxy operates its own LRU-list of a certain capacity in the shared cache. The length of objects simultaneously appearing in plural LRU-lists is equally divided among them, i.e., object sharing among the LRUs. We give numerical results for our MemCacheD with Object Sharing (MCD-OS) prototype. Also, a working-set approximation for the shared cache is described and how to reduce ripple evictions is discussed.
