CDN stands for content delivery network, of which there are many types, shapes and sizes. A CDN is a geographically distributed network of servers designed to deliver web content quickly and reliably around the world. Each CDN is strategically placed to be closer to end users, which helps reduce latency, alleviate origin server load, reduce the chance of buffering events and improve page load speeds. The lower the latency and the higher the quality of experience (QoE) for each user, the more effective a CDN is considered to be. However, while CDNs have become a standard in digital infrastructure, they do have their limitations. Traditional CDN models still rely heavily on centralized architecture, struggle with real-time adaptability, and often incur high operational costs. As content consumption patterns change and audiences grow more globally dispersed and mobile, content producers must ensure these conventional content delivery systems are successfully meeting user demand and expectations. 

In this article, we’ll explore how CDNs work, where they can fall short in meeting modern content delivery demands, and how next-generation solutions, such as our Data Logistics Platform, are helping to meet modern consumer expectations.

How do CDNs work?

Traditional CDNs work by caching content across a globally distributed network of servers, often referred to as edge nodes. When a user requests content, such as a video stream or website content, the CDN attempts to deliver it from the nearest available server, reducing the physical distance the data must travel. This approach helps lower latency and offloads traffic from origin servers, providing faster and more reliable content delivery under typical conditions. But today, proximity alone often isn't enough.

Most traditional CDNs operate blindly. They lack real-time insights into network congestion and the actual state of the open internet. As a result, they default to what’s often referred to as a “spray and pray” approach, meaning that content is sent through predefined routes without knowing whether those paths are optimal. This inefficiency becomes particularly problematic during traffic spikes, when lots of viewers are asking to watch the same event, or in regions with limited infrastructure. System73’s approach however is based on real-time visibility, data and peer-to-peer networks to make more informed decisions about where and how content is delivered.

Meeting modern content delivery demand

Meeting modern content delivery demand, particularly for video and live streaming, requires an in-depth understanding of how consumers today behave and what they expect from streaming services. The proliferation of mobile devices and the widespread availability of high-speed internet have transformed how audiences consume content. For instance, U.S. residents now spend an average of over three hours daily watching video content on mobile phones alone, which underscores the need for content delivery networks to optimize content and bitrates for mobile devices, ensuring smoother viewing. 

Live sports streaming has emerged as a noteworthy trend that has begun to influence how content providers set up their delivery architecture. Its growing popularity has driven an increasing demand for real-time, low-latency content delivery, as fans expect high-quality streams without delays or buffering. Traditional CDNs, while effective in certain scenarios, can struggle to meet these expectations due to their reliance on static infrastructure, meaning viewers in more rural locations can suffer from subpar streaming quality.

System73’s Data Logistics Platform helps meet consumer expectations through peer-to-peer content delivery

System73’s Data Logistics Platform takes a different approach to content delivery. Instead of relying on physical CDN infrastructure to deliver video content around the world, we integrate AI-driven logistics with a peer-to-peer (P2P) network architecture. Fueled by our proprietary analytics and content delivery solutions, the Platform scans the open internet in real-time to find the most optimal pathways with the least congestion. It then dynamically constructs centrally orchestrated broadcast trees, enabling real-time scalability and efficient content distribution, as well as offloading of up to 80% of streaming traffic from traditional CDNs, thereby reducing operational costs. 

By leveraging end-user devices as part of the delivery network, the Data Logistics Platform maintains high-quality streams even in regions with limited infrastructure. This method not only improves content delivery efficiency but also provides a sustainable alternative by minimizing reliance on centralized data centers. Security is also maintained through the use of the WebRTC protocol, which encrypts all data transfers using DTLS, ensuring secure peer-to-peer connections. Our SDK also includes authentication mechanisms to verify client identities and control access, further safeguarding content and viewer safety.
