Performance

CDN providers are adopting AI-driven traffic routing to optimize performance, particularly for video streaming and gaming. Machine-learning algorithms reduce egress costs by 20-30% for hyperscalers, improving throughput during traffic spikes. This enhances user experiences by minimizing latency. AI analyzes real-time data to route traffic through optimal PoP locations, bypassing congested paths. This improves TTFB and reduces p99 latency, critical for real-time applications. The cost savings benefit providers and customers alike. The technology is especially impactful for Multi-CDN setups, where AI coordinates traffic across multiple providers. However, implementation requires robust data pipelines, increasing complexity. Adoption is growing among large-scale platforms. ...

CDN providers like Akamai and Edgio are enhancing live streaming capabilities to support low-latency delivery for cloud gaming and AR/VR. These advancements reduce buffering and improve user experiences, critical for interactive media. CDNs are pivotal for large-scale events. Features like adaptive bitrate streaming and real-time analytics optimize delivery from origin to edge. By leveraging HTTP/3 and QUIC, CDNs achieve faster TTFB, lowering p95 latency for dynamic content. This ensures smooth playback under variable network conditions. Multi-CDN setups amplify reliability for live events, distributing traffic across providers. However, ultra-low-latency requirements challenge existing PoP infrastructure. Providers are scaling edge nodes to meet demand. ...

CDN providers are increasingly integrating edge computing to support real-time applications like video streaming and cloud gaming. By processing data closer to users, CDNs reduce latency, critical for delivering seamless experiences. The rise of 5G networks amplifies this trend, enabling faster content delivery. Edge computing shifts workloads from centralized origin servers to distributed PoP locations. This minimizes round-trip times, improving TTFB for dynamic content. For example, gaming platforms benefit from lower p95 latency, ensuring smoother gameplay during traffic spikes. ...

Indian Railways has upgraded its e-ticketing platform with CDN enhancements, achieving a record 31,800 tickets booked per minute on May 22, 2025. This boost improves access for millions of users, reducing latency during peak booking periods. The upgrade underscores CDNs’ role in high-traffic public services. The system leverages CDN caching and AI-driven traffic management to handle surges at PoP locations. Enhanced origin shielding protects against unauthorized access, ensuring stable performance. The 31,800 tickets-per-minute figure reflects a significant capacity increase, critical for user satisfaction. ...
