Understanding the Internet Ecosystem: From Your ISP to the Global Network

When you pay your Internet Service Provider (ISP) for your internet services, your payment covers a multitude of costs. This includes infrastructure, peering and transit agreements, and even content delivery. Let's delve deeper into these aspects and understand who provides internet to the ISPs and who owns the internet.

What Your ISP Pays for

Your ISP's payment covers:

Infrastructure Costs: ISPs invest in and maintain their own infrastructure, including cables, routers, and data centers. Peering and Transit Agreements: These agreements allow ISPs to exchange network traffic with other networks. Some ISPs pay for transit services, while others have peering agreements where they exchange traffic for free. Content Providers: Some ISPs pay content delivery networks (CDNs) or large content providers like Netflix, Google, etc. for better access to content.

Who Provides Internet to the ISPs?

ISPs obtain their internet connectivity through various means:

Upstream Providers: These are the larger ISPs or backbone providers that offer internet transit services to smaller ISPs. They have extensive networks and connections to the global internet. Peering Arrangements: ISPs may establish direct connections with other networks to exchange traffic. This can be more cost-effective and improve performance. Data Centers and Cloud Providers: ISPs also connect to data centers that host content and applications, providing access to services hosted there.

Who Owns the Internet?

The internet is not owned by any single entity. It is a decentralized network consisting of:

Internet Service Providers (ISPs): These provide the last-mile connection for homes and businesses to the internet. Content Providers: Companies like Google, Amazon, and others host websites and services and maintain their own infrastructure. Organizations and Standards Bodies: Groups like the Internet Corporation for Assigned Names and Numbers (ICANN) and the Internet Engineering Task Force (IETF) help manage and develop standards for the internet.

The Role of Your ISP: Like a Post Office

Your ISP acts much like a post office. They get paid for delivering websites to you. The data you access, such as Facebook, YouTube, and Quora, sit in data centers like those operated by Oracle, AWS, and Azure. An ISP’s job is to connect you to those data centers, providing you with websites and services you need.

Conclusion

In summary, the internet is a collaborative network of many different entities, each contributing to its infrastructure and governance. Understanding the layers of this complex system can help us appreciate the value of the internet and the role of each player in it.
