分布式对象缓存框架设计研究

对象缓存是一种通过在使用对象后不立即释放，而是存储在内存或硬盘中并被后来的客户端请求重用，避免重新建立对象的昂贵成本的机制。在考查了业界广泛使用的几种对象缓存框架后，提出了一种分布式对象缓存框架的设计方案LiteCS。该框架中服务器不需要负责对象更改消息的传递，即使缓存对象被频繁地修改，也不会大大增加系统的整体负载，可有效降低网络负荷．现所做的两组测试证明了LiteCS框架适用于多台服务器通过网络共享缓存对象。

Design of distributed object cache framework

Object cache is a mechanism of storing objects in memory or hard disk rather than releasing them immediately after their employment and the cached objects are accessible by the client side later on.This mechanism could account for saving on the vast cost of recreating objects.After digging into several object cache frameworks that had already gained much prevalence in the realm,a distributed object cache framework designing scheme named LiteCS is proposed.This framework liberates the server side from delivering object updating messages,even if the cached objects are frequently updated,there is no much heavier burden placed on the whole system.The experiments show liteCS offers a more efficient strategy to harness the net resources and can be well applied to the share service of cached objects in multi-servers structure.
