迅雷快鸟是迅雷快鸟与网络运营商合作推出的在线加速服务。其技术原理是大幅提高现有用户的物理宽带带宽,提高互联网速度,使用户可以在观看视频、游戏、购物、下载文件等场景时享受宽带宽带加速。

The principle of fast bird broadband acceleration is as follows:

迅雷快鸟加速的原理如下:

Table a: when "a network user" visits the CDN acceleration site, query the domain name from the local DNS, and finally obtain the IP address corresponding to the domain name in the global Intelligent DNS server, as shown in the figure: IP address of the a network cache server; then, the browser of the network user initiates an access request to the network cache server. Fortunately, the required default page file is only cached in network a. The cache server immediately returns data and completes an access request.

A:当“网络用户”访问CDN加速站点时,从本地DNS中查询域名,最终得到全局智能DNS服务器中域名对应的IP地址,A网络缓存服务器的IP地址;然后,网络用户的浏览器启动对网络缓存服务器的访问请求。幸运的是,所需的默认页文件仅缓存在网络A中。缓存服务器立即返回数据并完成访问请求。

Table B: when network B users visit CDN accelerated sites, query the domain name from the local DNS, and finally obtain the IP address corresponding to the domain name in the global Intelligent DNS server, as shown in Figure 7: IP address of network B cache server. Network B user browser initiates an access request to network B cache server, but the cache server does not cache the default page file, which requires obtaining this object from the source, caching and Return the content to B network user. The cache server of network B knows the location of the source station through the internal DNS.

B:当网络B用户访问CDN加速站点时,从本地DNS中查询域名,最终在全局智能DNS服务器中获得与域名对应的IP地址,Network B缓存服务器的IP地址所示。网络B用户浏览器启动对网络B缓存服务器的访问请求,但缓存服务器不缓存默认页文件,这需要从源获取此对象,缓存并将内容返回给B网络用户。网络b的缓存服务器通过内部dns知道源站的位置。

Simply put, when your resources are loaded on the CND server, and then each place views the resources, it is equivalent to visiting the nearest server resources, rather than directly visiting the original site resources of the website, which greatly reduces the pressure of visiting the original site.

简单地说,当你的资源加载到cnd服务器上,然后每个地方查看资源,就相当于访问最近的服务器资源,而不是直接访问网站的原始站点资源,这大大降低了访问原始站点的压力。

But how?

但是怎么做呢?

Compression? This is unlikely. If the advanced compression algorithm is adopted, the first step is to compress the information source and decompress the data locally. The same compression algorithm can not be applied to all kinds of protocols in the whole network.

压缩,如果采用先进的压缩算法,首先要对信息源进行压缩,并对数据进行局部解压缩。同一种压缩算法不能适用于整个网络中的各种协议。

Change course? After path tracking, it is found that the acceleration and non acceleration path information are unchanged, and the PPPoE mode is controlled by the PPPoE server. The final takeout is in the hands of operators, and it is impossible for a third party to bypass it by optimizing the route.

改变路线?路径跟踪后发现加速度和非加速度路径信息不变,pppoe模式由pppoe服务器控制。最终的网速掌握在运营商手中,第三方不可能通过优化路线绕过它。

Cooperate with operators to dynamically adjust PPPoE bandwidth, and share profits by quickly discovering birds. This may be the only possibility. This dynamic adjustment of bandwidth makes full use of bandwidth resources. Moreover, at present, Thunderbird adopts the way of paying users to speed up, avoiding some risks of operators themselves, using idle bandwidth to increase profits, and improving brand and product awareness. Although there is no breakthrough in technology, this way is really novel and all parties benefit from it. It's no problem.

与运营商合作,动态调整pppoe带宽,通过快速发现小鸟分享利润。这可能是唯一的可能。这种带宽的动态调整充分利用了带宽资源。而且,目前迅雷快鸟采取付费用户提速的方式,规避运营商自身的一些风险,利用闲置带宽增加利润,提高品牌和产品知名度。虽然在技术上没有突破,但这种方式确实很新颖,各方都从中受益
