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。

Abstract:

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.

Key words: in-network caching, information-centric networking, error recovery, flash crowd relief, DDoS attack prevention, popular content hosting, commission service
