Time is of the essence when it comes to loading websites or using applications on the web. Sluggish performance may result in losing potential clients. This is where advanced routing methods become extremely helpful.
The Anycast network is an innovative network addressing scheme that enables many different physical servers to possess one IP address. It allows directing web traffic not to one particular device but to the nearest server automatically.
To know what is anycast network, let us take a closer look at traditional traffic routing:
There are a number of important benefits that are brought by using Anycast networking.
Since Anycast redirects users’ requests to the closest server, there are fewer physical miles for data to travel. This ensures lower latency and thus improves DNS lookup speed.
In case of server unavailability caused by maintenance or hardware failure, Anycast handles this situation very efficiently – there is an automatic switch to the nearest available server.
Anycast provides efficient balancing of web traffic, since all user requests are distributed between numerous PoPs (points of presence) and therefore there is no risk that some particular node will get overloaded.
Distributed Denial of Service (DDoS) is one of the most common cyber-attacks directed at flooding the servers of websites. Anycast networks help explain how attack traffic is distributed across multiple servers.
The definition of an Anycast network reveals the importance of Anycast as an essential part of modern infrastructure. The usage of a single IP in different global nodes allows for top speed, DDoS protection, and high availability.
Ans: An Anycast network decreases latency as it routes traffic to the nearest server.
Ans: In case of server failure, traffic is routed to another server.
Ans: Yes, because Anycast spreads attack traffic across several servers.
