Description

—种CDN动态加速的系统及方法 - Species CDN system and method of dynamic acceleration

技术领域 FIELD

[0001] 本发明涉及一种系统及方法,尤其是一种CDN动态加速的系统及方法,属于CDN的技术领域。 [0001] The present invention relates to a system and method, in particular, a system and method of dynamic acceleration CDN, the CDN technical field.

背景技术 Background technique

[0002] Q)N的全称是Content Delivery Network,即内容分发网络。 [0002] Q) N stands for Content Delivery Network, i.e. the content distribution network. 其基本思路是通过在网络各处放置节点服务器,以通过节点服务器构成的在现有的互联网基础之上的一层智能虚拟网络,从而避开互联网上可能的速度瓶颈和不稳定的网络环节,使内容传输的更快、 The basic idea is that by placing a server node in the entire network, with a layer of intelligence on top of the existing Internet infrastructure composed by virtual network node server, thus avoiding possible speed bottlenecks and unstable Internet network link, the faster transmission of content,

更稳定。 more stable.

[0003] CDN系统能够实时地根据网络流量和各节点的连接、负载状况以及到用户的距离和响应时间等综合信息将用户的请求通过智能DNS重新导向离用户最近的服务节点上,目的是使用户可就近取得所需内容,解决Internet网络拥挤的状况,提高用户访问网站的响应速度,如图1所示。 [0003] CDN system can in real time based on the comprehensive information of network traffic and the respective nodes connected to the load conditions and the user's distance and response time to user requests re-directed through intelligent DNS from the user nearest service node, purpose is to make users can go to obtain the necessary content to address the Internet network congestion condition and improve the response speed of the user access to the site, as shown in Fig.

[0004] 在传统的⑶N系统中,用户通过智能DNS被解析到最近的⑶N服务节点上,用户发送请求给CDN节点,CDN服务节点先在缓存中查找是否有该请求的回复,如果有,则迅速将该回复反馈给用户;如果在缓存中没有该回复,则自动将请求转发给源站点,并将源站点的回复发送回用户,同时也将该回复保存在CDN节点内,这样对于后续用户的相同请求时就可直接从CDN缓存中提取回复内容。 [0004] In a conventional ⑶N system, the user is resolved by intelligent DNS to the nearest ⑶N service node, the user sends a request to the CDN node, CDN service nodes to find whether there is the request reply cache, if so, the quick to respond back to the user; if the reply does not in the cache, then automatically forwards the request to the source site, and the reply is sent back to the source user station, but also the reply stored in the CDN node, so the user for subsequent can be extracted from the reply buffer when the same CDN requests directly.

[0005] 传统的CDN结构可以非常有效地提高静态内容的访问速度,但对于动态内容却存在致命的缺陷,因为对于动态内容来说,CDN节点的缓存功能起不到任何作用,用户对于动态内容的获取只是通过⑶N节点做转发,最终都是从源站点获取,因此⑶N系统对动态内容几乎没有加速作用。 [0005] The traditional CDN architecture can very effectively increase the access speed of static content, but for dynamic content is fatally flawed, because for dynamic content, the cache function CDN nodes not have any effect, dynamic content for the user get just do forwarded through ⑶N nodes are ultimately obtained from the source site, so ⑶N system is almost no effect on accelerating dynamic content. 如图2所示,在传统CDN系统中,用户对静态内容获取时间仅等于用户到CDN节点的时间Tl,而对动态内容的获取时间为用户到CDN节点的时间Tl,同时还应加上⑶N节点到源站点的时间T2。 2, CDN in conventional systems, a user static user content acquisition only for the duration of the time CDN node Tl, while the acquisition time of dynamic content for the user to time Tl CDN node, but should be added ⑶N the source node to the site of the time T2.

[0006] 针对传统⑶N系统的这一缺陷,其主要原因在于:用户对于动态内容的请求必须从源站点获取,CDN节点只起到了转发的作用,虽然CDN系统中通过智能DNS可为用户选择最近的CDN节点,从而最大限度的缩短了Tl的时间;但对于动态内容,CDN节点到源站点的时间T2不可控,因此T2时间值就决定了动态内容的访问效率。 [0006] Due to this weakness of traditional ⑶N system, mainly due to: the user must obtain a request for dynamic content from the source site, CDN node forwards only played a role, although CDN intelligent DNS system by the user can select the nearest CDN node, thereby minimizing shortening the time Tl; but for dynamic content, the CDN node to the source site time T2 of uncontrollable, so the value of time T2 determines the efficiency of the dynamic content to access. 传统的CDN系统中缺少这样一种有效保障CDN节点到源站点之间的网络速度的方法。 Such a method to effectively protect the CDN node network between the source site CDN conventional systems lack.
