What is Traffic Director?

Do you want to give your users the best possible performance? The Traffic Director can help you to do that! With it, you can direct DNS queries through strategically placed nameservers, optimizing your query traffic with custom regionalization. Want to learn more? Let’s explore more details about how it functions and the benefits that it brings.

Explanation of Traffic Director 

Traffic director is a way to optimize and manage the traffic going to your domain by using geographical-based routing. Like this, your clients from Asia will get connected to your Asian servers; your European clients will connect to the closest servers they have in Europe and so on.
Traffic Director is a cloud-based implementation of Load Balancing (you can check our article on Load Balancing). It helps to improve the performance of your network. It can be incredibly useful for medium and large companies that need to deliver content to different parts of the world.

Some companies call this service traffic director, others Global Traffic Director (GTD) or GeoDNS director, but it is best known as GeoDNS, and that is why we use this term as the name of our service.

How does it perform?

Traffic Director gives you easy access to a powerful global load-balancing system by making configuration easy. All you need to do is set your own regional rules, and the Traffic Director will intelligently direct DNS queries through strategically-placed nameservers.

ClouDNS enables you to optimize your query traffic with custom regionalization, allowing you to divide traffic across six global regions:

  • Africa
  • Asia
  • Europe
  • North America
  • Oceania
  • South America

By leveraging Traffic Director, you can ensure your site visitors have a better experience. For example, through regionalized configurations, queries are redirected to the geographically closest nameservers, meaning Chicago visitors would be answered by a nameserver in the North American region rather than relying on a Asia or even overseas-based server.

Traffic Director

In addition, If you want to ensure users from France, for example, receive the best possible experience, the Traffic Director can help you achieve this. Its regionalized configurations enable you to specify that all DNS queries from the country-based region (France) should be answered by a server located in Paris. This means you can ensure users are connected to the closest, most efficient nameserver. 

DNS lookups are the first step in making any DNS request. In order to produce the best user experience, DNS traffic must be routed efficiently and with purpose. If it is not handled optimally, it can lead to poor performance and contribute to a degraded user experience. By using a Traffic Director, you can ensure users get the speedy, reliable performance they deserve.

Typical DNS vs. Anycast vs. GeoDNS

Typically, you will have few DNS servers. A visitor trying to connect will ask at random one of them for your web server’s IP address. The visitor will be lucky if the server is close and not so happy if it is far away, but he or she will get the same IP address.
If you are using just an Anycast, multiple servers will respond to the same IP. With it, the visitor will get a response from the topologically closest nameserver. The reaction is quick, but it still can take time to connect to the web server if it is far away.
Here comes the GeoDNS/Traffic Director and its advantages. By using it, a visitor will get a different IP address, depending on his/her location. It will result in fast DNS query response and consequently fast connection to the web server.
