How Internet Exchange Points (IXPs) Power Global Connectivity?

Do you wonder why videos flow smoothly on your device or how websites instantly load for you? The internet of today seems magical to us because it has a very complex physical infrastructure that underpins its working. 

Among the many components of this infrastructure, there is one vital component that helps the whole system run efficiently: internet exchange points. Without these facilities, our online experience will be extremely slow and expensive.

What Are Internet Exchange Points?

In simple terms, Internet Exchange Point (IXP) is a physical location where several networks meet to exchange their traffic in a direct manner. In simple language, an IX facility is like the central station of the subway where all trains meet to change their paths. Instead of having to go through a long route via third party transit operators, the networks meet physically and transfer data.

The Magic of How Data Works

In order to illustrate how it works, visualize two local Internet Service Providers (ISP) within the same city. 

If there were no IXPs, any attempt by a person on network A to communicate with his friend on network B would require the data to travel all the way around the world just in order to end up in the next-door building.

• Shared Fabric

  The IXP consists of physical routers from ISPs, content delivery networks, and tech companies connected to a shared switching system.

• Smarter Routing

  With the help of standardized routing methods such as the Border Gateway Protocol, they automatically find the shortest possible routes to exchange data.

Major Advantages of IXPs

In reducing the distance the data has to travel, IXP plays a major role in improving the quality of our everyday online experience.

• Improved Response Time: Shortened distance will make for less delay, which means no buffering in video calls or movies.
• Savings: Since there is no need to pay any extra money via third-party brokers, your home internet costs will go down.
• Increased Reliability: Should anything happen to your external link connection, all local traffic will be left untouched since the networks will be connected directly anyway.

Conclusion

In conclusion, the internet performs optimally when it runs locally. Internet exchange facilities are what make it possible for data to flow optimally across the world. They connect content owners and local networks in one facility, ensuring that the entire internet network is fast and efficient enough to take us into the future. While IXPs strengthen the internet’s backbone, users can also optimize their home network for better performance.

Moreover, as the bandwidth needs of the world continue to increase due to technologies such as smart cities and artificial intelligence, these facilities are going to become more important than ever before.
