Anycast Routing: The Basics and Why You Should Use It
Anycast routing is a single destination point that uses multiple paths to reach its endpoint. It takes all incoming traffic into the nearest data center and routes it to the proper destination. It helps to reduce the impacts of traffic congestion and high volume.
The most popular type of anycast routing is the CDN. The CDN works with multiple geolocation database providers to ensure that all traffic is routed to the proper location across the internet.
Some of the more popular geolocation database users include sites like Amazon, Facebook, Instagram, Twitter, and Netflix.
The Four Benefits To Using Anycast Routing
1) The connections are going to be more efficient and faster. There are fewer hoops to jump through with anycast routing. The Round-Trip Time(RTT) has increased value. That means latency is reduced. The user experience is friendlier and more efficient. In other words, you get where you need to go in a timelier fashion.
2) You will only need one DNS server. That server works with multiple lines regardless of the number of users on the network. The older methods use multiple servers for one connection. That makes a big difference when it comes to business and branding.
3) There is something called a DDOS(denial-of-service attack). Anycast uses DDOS mitigation techniques that stop an attack before it starts. Say one node is taken offline and pinpointed for an attack. Sometimes an attack hits more targets when it is offline. That way users do not see it coming.
The DDOS mitigation works to protect the network from being exposed, even when you are offline.
4) Anycast provides a backup in case one of the networks shuts down. Sometimes the circuits become overloaded. They shut down for a bit. Every IP address has multiple nodes working. That way the routing can provide a backup in case something were to happen.
Four Methodologies Included With Anycast Routing
Four other components work with anycast routing to make sure users get the ultimate experience.
1) There is Unicast, which is referred to as “one-to-one.” That is when at least two networks need to communicate with one another. The endpoints keep each network under its single directive, but it does aid with communication.
2) There is Broadcast, which is referred to as “one talking with many.” One network broadcasts multiple points using one endpoint. The network will duplicate any points that are needed as time moves on.
3) There is multicast, which is when a sender sends out specific endpoints to multiple receivers. The difference between this and broadcast is that the notification is not sent to every line. It is only sent to the lines on the list.
4) There is something called “geocast”, which is when endpoints are delivered to specific locations. It is a more advanced form of the multicast. The sender communicates information depending on the location. The other difference between this and multicast is that it combines things like mobile geolocations and hoc networks.
