The project investigates two traffic distribution strategies: BGP-based anycast versus DNS-based distribution, with initial experiments measuring latency differences between the two approaches. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What are the two main approaches to directing traffic in a CDN? The two main approaches are BGP-based anycast and DNS-based distribution. BGP anycast advertises the same IP prefix from multiple locations so routing infrastructure directs users to the nearest node, while DNS-based distribution uses geographic or latency-aware DNS responses to steer users. Both have different latency characteristics that can be measured experimentally. _Engineers weighing CDN routing strategies find real-world comparisons like this on daily.dev._ ## Similar posts on daily.dev - [500 Tbps of capacity: 16 years of scaling our global network](https://daily.dev/posts/500-tbps-of-capacity-16-years-of-scaling-our-global-network-epwhxsyeu) · Cloudflare · 0 upvotes · 0 comments - [Self-Hosting Behind CGNAT](https://daily.dev/posts/self-hosting-behind-cgnat-lrdls1bcr) · Lobsters · 1 upvotes · 0 comments - [What Is a CDN and Does Your Website Need One?](https://daily.dev/posts/what-is-a-cdn-and-does-your-website-need-one--fhqqqhfnh) · Telerik · 0 upvotes · 0 comments - [UDP Broadcasting And The Brave New World Of IPv6](https://daily.dev/posts/udp-broadcasting-and-the-brave-new-world-of-ipv6-kbr2qsudb) · Hackaday · 0 upvotes · 0 comments - [Improving NAT traversal, pt. 3: looking ahead](https://daily.dev/posts/improving-nat-traversal-pt-3-looking-ahead-sd7jm9lvd) · Tailscale · 0 upvotes · 0 comments --- Tags: [#dns](https://daily.dev/tags/dns), [#bgp](https://daily.dev/tags/bgp) [View this post on daily.dev](https://daily.dev/posts/starting-my-content-delivery-network-mqufa0xed) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Starting my Content Delivery Network","url":"https://daily.dev/posts/starting-my-content-delivery-network-mqufa0xed","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/starting-my-content-delivery-network-mqufa0xed"},"datePublished":"2026-08-11T08:56:26.177Z","dateModified":"2026-08-11T09:35:13.891Z","description":"A personal project exploring how to build a small-scale content delivery network using a self-owned Autonomous System Number (ASN).
