摘　　要：作为信息中心网络(information-centric networking,ICN)的特色之一,网络缓存在彰显ICN的优势方面扮演着重要的角色,但当前对网络缓存所扮演的具体角色没有一致的看法。指出网络缓存应具有三级缓存,解释这三级网络缓存可以在错误恢复、突发访问缓解、DDoS攻击防治、热点内容缓存及托管服务方面起一定的作用,并说明了实现这些角色需要解决的问题。The universal in-network caching, as a prominent feature of information centric networking （ICN）, plays important roles in the demonstration of ICN＇ s advantages over other architectures. But so far, many people still have different perception of it. The specific roles that in-network caching can play should be first explored before it can be taken full advantage were argued. Such exploration by pointing out three levels of in-network caching were argued, explained how the three-level in-network caching play roles in error-recovery, flash crowd relief, DDoS attack prevention, popular content hosting and commission service, and stating issues related to these roles.
