What is a CDN
Content delivery networks (CDNs) are the transparent backbone of the Internet in charge of content delivery. Whether we know it or not, every one of us interacts with CDNs on a daily basis; when reading articles on news sites, shopping online, watching YouTube videos or perusing social media feeds.
CDN consists of THREE Major Components:
- Caching – Thousands of proxy-cache servers spread over the world
- Routing – Helps a user to make its request to the nearest caching server
- Network – Reserved bandwidth capacity on multiple Carriers and ISPs to ensure high speed between a caching server and the user
How Typical CDNs Work
User request sent to a CDN or origin server
Traffic transits the entire telco-core / gateway network infrastructure
Multiple users for the same content will consume the backhaul / transit bandwidth
Request Latency typically measured in 100’s of Milliseconds
Challenges with handling high bandwidth cases such as Live Streaming, Live Events and Online Gaming
How it works with picoCDN
- Traditional CDN models majorly comprise three points of distribution, such as Cloud Data Center, Internet Exchanges, and Internet Service Provider NOC. This only provides limited performance.
- With picoCDN additional layer of PoP’s at the edge, we are only ONE hop away from the user, thereby enhancing performance to a whole new level.

Breakout can be Native
(5G-NGC/UPF), CUPS
(4G-R14+) or Bump-in-the-Wire (3GPP Pre R14)
Edge served requests skips the entire Telco core / gateway network infrastructure
Request Latency typically measured in 10’s of Milliseconds
Supports large scale Live Events and other High Bandwidth use cases
Multiple users for the same content will not stress Backhaul/Transit Bandwidth
