What is Anycast?
Anycast is a way to route network traffic that dramatically increases the speed and reliability of your data, application, and content delivery to your users. With anycast routing, one IP address becomes reachable at multiple geographic locations. The many benefits to using anycast routing include:
Anycast enables user requests to be directed to the location closest to them geographically, minimizing round-trip time (RTT), decreasing the number of hops, and reducing latency.
Anycast utilizes redundant servers, making your service becomes much more available. If one location is down for any reason, users are sent automatically to the next closest location.
Routing users to multiple locations effectively balances the load among the your servers, improving speed and performance.
Anycast reduces the impact of DDoS attacks (when a server is overloaded with requests and crashes). With anycast, requests are fulfilled by other locations during mitigation and recovery.
Anycast vs Unicast
One the the easiest ways to understand anycast routing is to compare it to the more commonly-used unicast routing.
Unicast to Multiple Locations
With unicast routing, all requests are directed to one point of presence, leaving your users frustrated when your servers at that location go down for any reason.
NetActuate Anycast Deployment
User requests are sent to the point of presence they are physically closest to. If one point fails, users are immediately sent to the next closest location.
