扩展资料：

CDN的全称是Content Delivery Network，即内容分发网络。CDN是构建在现有网络基础之上的智能虚拟网络，依靠部署在各地的边缘服务器，通过中心平台的负载均衡、内容分发、调度等功能模块，使用户就近获取所需内容，降低网络拥塞，提高用户访问响应速度和命中率。CDN的关键技术主要有内容存储和分发技术。

CDN具有以下主要功能：

(1)节省骨干网带宽，减少带宽需求量；

(2)提供服务器端加速，解决由于用户访问量大造成的服务器过载问题；

(3)服务商能使用Web Cache技术在本地缓存用户访问过的Web页面和对象，实现相同对象的访问无须占用主干的出口带宽，并提高用户访问因特网页面的相应时间的需求；

(4)能克服网站分布不均的问题，并且能降低网站自身建设和维护成本；

(5)降低“通信风暴”的影响，提高网络访问的稳定性。
