Hotspot content caching system and hotspot content caching method

The invention discloses a hotspot content caching system. IPv6 conversion is carried out on IPv4 network content with large access amount of the IPv6 terminal through the address conversion system bythe content aggregation pool; or IPv6 conversion is carried out on the IPv4 network content with large user access amount through the address conversion system; the content is automatically cached ina content aggregation pool, so the IPv6 terminal or the IPv4 terminal ,which need to access the same content can access the content, and the same hotspot content can be directly extracted from the content aggregation pool without being converted for multiple times when being accessed by a plurality of IPv6 terminals or IPv4 terminals, so that the hotspot content can be repeatedly utilized, the influence on the system performance is small, the burden of an address conversion system is reduced, and the operation cost of the system is further reduced. 本发明公开了一种热点内容缓存系统，通过内容聚合池将IPv6终端访问量大的IPv4网络内容通过地址转换系统进行IPv6转换，或者将用户访问量大的
