Dynamic DNS server

Normally a server is not reachable from the Web at large without a static IP address, but a dynamic DNS service allows me to set up a temporary resolvable machine name under another top-level domain.

通常，如果一个服务器没有静态IP地址，那么来自Web上的访问流量就不可能太大，动态dns让我们可以在另外一个顶级域名之上临时建立一个可解析的机器名。

In order to ensure that its DS-integrated peer DNS servers are able to replicate with this server, an attempt was made to update them with the new records through dynamic update.

为了保证它的DS集成对等DNS服务器能与此服务器进行复制，尝试通过动态更新用新记录更新它们。

Then, an improved AR(1) model is proposed. Through this new model, the response time of a DNS server can be dynamic predicted using previous response time series.

同时，基于已有的AR（1）模型，提出了一种改进型AR（1）自回归模型，该模型能够利用历次服务器响应时间构成的时间序列，采用动态预测的方法来预测服务器响应时间。
